Syntax Description

hookflash

Sends persistent hookflash events to the call agent.

offhook

Sends persistent off-hook events to the call agent.

onhook

Sends persistent on-hook events to the call agent.

Command Default

The hookflash keyword is disabled for persistence. The offhook keyword is enabled for persistence. The onhook keyword is disabled for persistence.

12.2(4)T

This command was integrated into Cisco IOS Release 12.2(4)T.

12.2(11)T

This command was implemented on the Cisco AS5300 and Cisco AS5850.

Usage Guidelines

Persistent events are those events that, once they are detected, are defined as reportable to the call agent whether or not the call agent has explicitly requested to be notified of their occurrence; that is, even if they are not included in the list of RequestedEvents that the gateway is asked to detect and report. Such events can include fax tones, continuity tones, and on-hook transition. Each event has an associated action for the gateway to take.

Use this command for each type of persistent event that should override the default behavior.

Examples

The following example configures the gateway to send persistent on-hook events to the call agent: 


Router(config)# mgcp persistent onhook

12.2(11)T

This command was implemented on the Cisco AS5300 and Cisco AS5850.

Usage Guidelines

If the network gateway cannot handle piggyback messages, us e the no form of this command to disable the piggyback messages and to enable Media Gateway Control Protocol (MGCP) 1.0, Network-based Call Signaling (NCS), and Trunking Gateway Control Protocol (TGCP). Piggyback messaging is not available to Simple Gateway Control Protocol (SGCP) and MGCP 0.1.

The term piggyback message refers to a situation in which a gateway or a call agent sends more than one MGCP message in the same User Datagram Protocol (UDP) packets. The recipient processes the messages individually, in the order received. However, if a message must be retransmitted, the entire datagram is resent. The recipient must be capable of sorting out the messages and keeping track of which messages have been handled or acknowledged.

Piggybacking is used during retransmission of a message to send previously unacknowledged messages to the call agent. This maintains the order of events the call agent receives and makes sure that RestartInProgress (RSIP) messages are always received first by a call agent.

Examples

The following example disables piggyback messages: 


Router(config)# no 
mgcp piggyback message

12.4(24)T3

The maximum number of MGCP profiles that can be configured was increased from 13 (12 plus 1 default) to 29 (28 plus 1 default).

Usage Guidelines

An MGCP profile is a subset of endpoints on a media gateway. More than one MGCP profile can be configured on a gateway at the same time. Prior to Cisco IOS Release 12.2(24)T3, the maximum number of MGCP profiles was 13 (12 plus 1 default). Beginning in Cisco IOS Release 12.2(24)T3, the maximum number of MGCP profiles is 29 (28 plus 1 default). The voice-port command in MGCP profile configuration mode associates endpoints with the profile.

There are two types of MGCP parameters: global and profile-related. The parameters that are configured in MGCP profile configuration mode are the profile-related parameters. However, endpoints do not need to belong to an MGCP profile. When endpoints are not associated with any MGCP profile, values for the profile-related MGCP parameters are provided by a default profile . Although all of the parameters for the default profile have default values, they can also be configured in the same way that an MGCP profile is configured by simply using the default keyword instead of a profile name. The main difference between a default profile and a user-defined profile is that there is no voice-port or call-agent association in the default profile, but they are required in user-defined profiles. When configuring the default profile, do not use the call-agent command or the voice-port command.

This command initiates MGCP profile configuration mode, in which you create an MGCP profile for an endpoint or a set of endpoints on a media gateway, and you set parameters for that profile or for the default profile.

Examples

The following example shows the definition of the MGCP profile named newyork: 


Router(config)# mgcp profile newyork

This command was integrated into Cisco IOS Release 12.2(2)T.

12.2(11)T

Usage Guidelines

The following impact the quality of voice calls:

  • Cell loss (the number of ATM cells lost during transmission)

  • Jitter buffer (storage area containing active call voice packets that have been received from the network and are waiting to be decoded and played)

  • Latency (network delay in sending and receiving packets)

  • Packet loss (number of packets lost per 100,000 packets for a given call)

For good voice quality, the system should perform below the low water mark values. As the values go higher, voice quality degrades. The system generates a report when the values go above the high water marks levels. Set the high water marks and low water marks values sufficiently apart so that you receive reports on poor performance, but not so close together that you receive too much feedback.

Enter each parameter as a separate command.

Examples

The following example sets various keywords to new values: 


Router(config)# mgcp quality-threshold hwm-jitter-buffer 100
Router(config)# mgcp quality-threshold hwm-latency 250

loop

Enables loop mode for quarantined events instead of stepping. After receiving a request from the call agent, the gateway reports the observed events to the call agent in multiples without waiting for subsequent requests.

process

Enables processing of quarantined events instead of discarding. Observed events are reported to the call agent when the call agent is ready to receive them.

step

Enables step mode for quarantined events instead of looping. After receiving a request from the call agent, the gateway reports observed events individually to the call agent, one for each request.

Command Default

If no event is specified the default is step .

This command was integrated into Cisco IOS Release 12.2(4)T.

12.2(11)T

This command was implemented on the Cisco AS5300 and Cisco AS5850.

Usage Guidelines

Quarantine events are defined as events that have been detected by the gateway before the arrival of the MGCP NotificationRequest command but that have not yet been notified to the call agent. They are held in the quarantine buffer until receipt of the MGCP NotificationRequest command, when the gateway is expected to generate either one notification (step by step) or multiple notifications (loop) in response to this request (the default is exactly one), based on the configuration of the mgcp quarantine mode command.

This command supports backward compatibility with SGCP implementations running under the MGCP application. SGCP does not have a way to allow the call agent to control the quarantine mode. MGCP has this functionality.

When the gateway is in the notification state, the interdigit timer (Tcrit) is not started.

When the gateway receives an unsuccessful NotificationRequest, the current RequestEventList and SignalEventList are emptied. The ObservedEventList and quarantine buffer are also emptied.

Changes to the quarantine mode only take effect when the gateway is rebooted or the MGCP application is restarted.

Examples

The following example starts the MGCP application: 


Router(config)# mgcp

The following example stops the MGCP application: 


Router(config)# no mgcp

The following example turns on processing of quarantined events and sends observed events to the call agent: 


Router(config)# mgcp quarantine mode process

The following example turns off processing of quarantined events: 


Router(config)# no mgcp quarantine mode discard

The following example sends observed events to the call agent in loop mode: 


Router(config)# mgcp quarantine mode process loop

12.2(11)T

Usage Guidelines

This command enables the reporting of persistent events immediately to the call agent rather than holding the events in quarantine. Persistent events are events defined as reportable whether or not the call agent explicitly has requested to be notified of their occurrence. Quarantining means that the gateway observes events but does not report them to the call agent until the call agent indicates readiness to receive notifications. By default, all events, including persistent events, are quarantined when they are detected, even when the gateway is in a notification state. When the mgcp quarantine persistent -event disable command is configured, however, persistent events are reported to the call agent immediately by an MGCP Notify command.

Examples

The following example disables quarantine buffer handling of persistent events: 


Router(config)# mgcp quarantine persistent-event disable

The cisco-codec-fax-ack and cisco-codec-fax-ind keywords were added.

Usage Guidelines

Cisco IOS Release 12.2(11)T introduced an RTP payload type negotiation for MGCP VoIP calls different from previous Cisco IOS images. To ensure interoperability between gateways using different Cisco IOS images, follow these guidelines:

  • For fax and modem codecs--If either the originating or terminating MGCP gateway is running Cisco IOS Release 12.2(11)T or a later release and the other gateway is running a release earlier than Cisco IOS Release 12.2(11)T, use the mgcp rtp payload-type command on the gateway with the later release.

  • For voice codecs--If you are using a Clear Channel, G.726R16, or G.726R24 codec, and either the originating or terminating MGCP gateway is running Cisco IOS Release 12.2(11)T or a later release and the other gateway is running a release earlier than Cisco IOS Release 12.2(11)T, use the mgcp rtp payload-type command on the gateway with the later release.

If both the originating and terminating gateways are using Cisco IOS Release 12.2(11)T or a later release, this command is not required.

The cisco-codec-fax-ack and cisco-codec-fax-ind keywords are used to change the default dynamic payload type for the Cisco fax relay feature to a different dynamic payload type.


Note

NSE and NTE cannot be configured to use the same value. An error message will be generated by the command parser if the same value is entered.

Examples

The following example specifies use of dynamic RTP payload type for fax and modem calls for mu-law pulse code modulation (PCM) calls in an MGCP network in which the other gateway is running a release of Cisco IOS software that is earlier than Release 12.2(11)T: 


Router# mgcp rtp payload-type cisco-pcm-switch-over-ulaw 126

The following example specifies use of a static RTP payload type for a G.726R16 codec in an MGCP network in which the other gateway is running a release of Cisco IOS software that is earlier than Release 12.2(11)T: 


Router# mgcp rtp payload-type g726r16 static

The following examples configure the gateway to use RTP payload 104 for NSE events and payload 108 for NTE events. These payload types are used when the gateway is advertising capabilities via the Session Definition Protocol (SDP). If the gateway is recieving the SDP, the payload types configured in the remote SDP will be used instead. 


Router# mgcp rtp payload-type nse 104

Router# mgcp rtp payload-type nte 108

12.2(2)T

This command was introduced.

12.2(11)T

This command was implemented on the Cisco AS5300 and Cisco AS5850.

Usage Guidelines


Note

This command replaces the previously hidden mgcp rtp icmp timeout command .

This command is useful for preventing calls from remaining open when the remote endpoint is no longer available.

For example, suppose an IP phone makes a call through a gateway to another IP phone. During the call, the call agent goes down and the remote IP phone hangs up. Normally, the call agent would tell the gateway to tear down the call. In this case, the gateway continues to treat the call as active and sends more voice packets to the remote IP phone. The remote IP phone returns Internet Control Message Protocol (ICMP) port unreachable messages to the gateway. If the mgcp rtp unreachable timeout command is enabled, the gateway tears down the call. If the command is disabled, the call is left open.

The timer-value argument tells the gateway how long to wait before tearing down the call. After receiving the ICMP the unreachable message, the gateway starts a timer. If the gateway does not receive any voice packets by the end of the timer-value period, the gateway tears down the call. If some voice packets arrive before the end of the timer-value period, the gateway resets the timer and leaves the call in active state.

Examples

The following example sets the Real-Time Transport Protocol (RTP) unreachable timer to 1500 ms: 


Router(config)# mgcp rtp unreachable timeout 1500

12.2(4)T

This command was integrated into Cisco IOS Release 12.2(4)T.

12.2(11)T

This command was implemented on the Cisco AS5300 and Cisco AS5850.

Usage Guidelines

This command allows you to configure SDP fields to meet the requirements of your call agent.

The notation undotted keyword is for the G.726-16 and G.729 codecs. The codec strings G.726-16 and G.729 are dotted notation. The codec notation format is selected dynamically in the following order of preference:

  1. The notation used in SDP for MGCP packets from the call agent.

  2. The notation used in the a: parameter of the Local connection option for MGCP packets from the call agent.

  3. The notation set by the mgcp sdp notation undotted command.

The simple keyword, w hen enabled, causes the gateway not to generate the following SDP fields: o (origin and session identifier), s (session name), and t (session start time and stop time). Certain call agents require this modified SDP to send data through the network.

The xpc -codec keyword, in TGCP and NCS, defines a new field (X-pc-codec) in the SDP for codec negotiation. To be backward compatible with nonpacket-cable SDPs, the initial generation of the X-pc-codec field is suppressed by default. However, if a received SDP contains this field, the X-pc-codec field is read and generated in response to continue with the codec negotiation.

Examples

The following example configures simple mode for SDP: 


Router(config)# mgcp sdp simple

Modification

12.2(11)T

This command was introduced.

Usage Guidelines

This command is used with SGCP version 1.5 to provide enhanced messaging capability for an endpoint that undergoes the disconnected procedure. It does not apply to gateways that run Media Control Gateway Protocol (MGCP) or other versions of SGCP.

An SGCP endpoint may lose communication with its call agent because the call agent is temporarily off line or because of faults in the network. When a gateway recognizes that an endpoint has lost its communication with the call agent (has become disconnected), it attempts to restore contact. If contact is not established before the disconnected timer expires, the disconnected procedure is initiated.

The disconnected procedure consists of the endpoint sending a Restart In Progress (RSIP) message to the call agent, stating that the endpoint was disconnected and is now trying to reestablish connectivity. If the mgcp sgcp disconnect notify command has been configured on the gateway, a special disconnected RSIP message is sent. When contact is reestablished, the call agent may decide to audit the endpoint using an Audit Endpoint (AUEP) command with additional I, ES, and RM parameters, which are defined as follows:

  • I--List of connection identifiers for current connections on the endpoint

  • ES--Event state of the endpoint (off-hook or on-hook)

  • RM--Restart method reason for the last RSIP (graceful, forced, restart, or disconnected)

Endpoint synchronization with the call agent is achieved by the exchange of the disconnected RSIP message and the endpoint audit.

Examples

The following example enables disconnected RSIP messaging between SGCP endpoints and a call agent: 


Router(config)# mgcp sgcp disconnect notify

12.3(10)T

This command was modified. The toh-time keyword was added to adjust the duration of silence between the 3 beep groupings used for tone on hold.

Usage Guidelines

Use this command to specify the RTP Control Protocol (RTCP) transmission interval for VoIP calls and the continuity-test timeout interval for VoIP and VoATM adaptation layer 2 (VoAAL2) calls.

The receive-rtcp keyword is the timer used by a gateway to disconnect a VoIP call when IP connectivity is lost with the remote gateway. After receiving each RTP or RTCP packet from the remote gateway, the receiving gateway starts a timer. The period of the timer is determined by multiplying the value configured using the mgcp timer receive-rtcp command with the value configured using ip rtcp report interval command. If the timer expires before the next packet is received from the remote gateway, the receiving gateway disconnects the call and notifies the call agent.

The net -cont -test keyword uses the terminating gateway to verify the network connectivity with the originating gateway before ringing the called party. To do this, the terminating gateway sends a command packet to the originating gateway and starts a timed for the timer period. If the timer expires before any acknowledgement from the originating gateway is received, the terminating gateway does not ring the called party, but instead disconnects the call and alerts the call agent.

The nse-response t38 option sets the timer for awaiting T.38 NSE responses. This timer is configured to tell the terminating gateway how long to wait for an NSE from a peer gateway. The NSE from the peer gateway can either acknowledge the switch and its readiness to accept packets or indicate that it cannot accept T.38 packets.

The toh-time timer option sets the duration of silence between the 3 beep groupings used for tone on hold.

Examples

The following example sets the multiplication factor to 10 (or x*10, where x is the interval that is set with the ip rtcp report interval command): 


Router(config)# mgcp timer receive-rtcp 10

The following example sets the net-cont-test timer to 1500 ms (1.5 seconds): 


Router(config)# 
mgcp timer net-cont-test 1500

The following example enables MGCP fax relay and sets the gateway wait time to 300 ms for an NSE from a peer gateway: 


Router(config)# mgcp timer nse-response t38 300

The following example enables tone on hold timer and set the duration of silence between the 3 beep groupings to 200 ms: 


Router(config)# mgcp timer toh-time 200

Usage Guidelines

The mgcp validate domain-name command enables validation of a hostname and domain (or specific IP address) received as part of the endpoint name sent from the call agent (CA) or Cisco CallManager against those configured on the gateway. If the hostname or domain (or IP address) is not valid, the system returns a 500 error with appropriate comment.

Use the mgcp validate domain-name command before configuring MGCP globally in a VoIP network. (See the Cisco Unified CallManager and Cisco IOS Interoperability Guide for global MGCP configuration information.)


Note

Only MGCP messages received from the CA or Cisco CallManager are validated .

You can display the current setting for MGCP domain name validation using the show running-config command. To show only MGCP information, limit the display output to the section on MGCP (see the "Examples" section).


Note

When MGCP domain name validation is disabled, the output of the show running-config command does not include this command--it displays only when domain name validation is enabled. However, if your system is running a software image released before the default for this feature was changed, MGCP domain name validation is turned on by default and will appear in the show running-config command output only if validation is disabled.

Once you enable the MGCP validate domain name feature, you should verify that the appropriate endpoint name is included as part of incoming MGCP messages. Performing this verification helps to ensure that incoming messages with invalid hostnames, domain names, and IP addresses are rejected while valid incoming messages are still allowed to reach their target endpoint (host). Enabling this validation feature without verifying this information can cause all incoming messages, even those using valid names or addresses, to be rejected (see the "Examples" section).

Examples

The following examples show how to enable MGCP domain name validation, how to verify that validation is enabled in the running configuration, and how to verify and match the hostname, domain name, or IP address specified in incoming MGCP messages to the gateway configuration.

Use the following command to enable MGCP domain name validation: 


Router(config)# mgcp validate domain-name

Use the following command to verify that MGCP domain name validation is enabled: 


Router(config)# show running-config | section mgcp

or 


Router(config)# show running-config | include mgcp validate
mgcp validate domain-name
Router(config)#

Use the following commands and processes to verify that hostname and domain name are configured so that all and only valid incoming messages are accepted by the gateway.

After enabling domain name validation, enable debug tracing for MGCP packets: 


Router# debug mgcp packets
Media Gateway Control Protocol packets debugging for all endpoints is on
Router#

Generate a call to the gateway from a CA or Cisco CallManager. That call will generate debug messages on the gateway so that you can view the endpoint information included in the incoming MGCP message and the response from the gateway to the CA (or Cisco CallManager): 


Router#
*Mar 14 02:29:11.512: MGCP Packet received from 192.0.2.135:2427--->

*Mar 14 02:29:11.512: MGCP Packet sent to 192.0.2.135:2427--->
500 3 Endpoint name contains an invalid host or domain
<---

Because the hostname in the incoming message (aaln/S2/SU0/0@Router2821.example.com) does not match the hostname of the gateway (Router), the message was rejected (replied to with a NACK). To resolve this, change the hostname of the gateway: 


Router# config terminal
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)# hostname Router2821
Router2821(config)# end
Router2821#

Generate another call to the gateway from the CA or Cisco CallManager. That call will generate more debug messages so that you can view the endpoint information included in the incoming MGCP message and the response from the gateway to the CA (or Cisco CallManager): 


*Mar 14 03:01:12.480: MGCP Packet received from 192.0.2.135:2427--->

*Mar 14 03:01:12.480: MGCP Packet sent to 192.0.2.135:2427--->
200 3 OK
<---

The validation is successful and an ACK (positive response) is sent back to the CA or Cisco CallManager because the hostname now matches. This same process also applies to validation for the domain name. Use the following commands to set the domain name for the gateway and to view current configuration for domain name and hostname: 


Router2821# config terminal
Enter configuration commands, one per line.  End with CNTL/Z.
Router2821(config)# ip domain-name example.com

Use the following commands and processes to verify that the IP address for the gateway is configured so that all and only valid incoming messages are accepted by the gateway: 


Router2821# show ip interface brief
Interface                  IP-Address       OK?    Method    Status    Protocol

Generate a call to the gateway from the CA or Cisco CallManager. That call will generate debug messages so that you can view the endpoint information included in the incoming MGCP message and the response from the gateway to the CA (or Cisco CallManager). If the MGCP message is directed to a specific IP address instead of a domain or hostname, you will see debug messages similar to the following: 


*Mar 14 03:16:52.356: MGCP Packet received from 192.0.2.135:2427--->

Because the IP address specified in the incoming message (aaln/S2/SU0/0@192.0.2.190) does not match the IP address of the GigE 0/0 interface (192.0.2.189), the message was rejected (replied to with a NACK). To resolve this, change the IP address specified by the CA or Cisco CallManager for this gateway and generate another call to this gateway. If the IP addresses match, you will see debug messages similar to the following:

Modification

12.3(3)

This command was introduced.

12.4(4)T

The priority and all keywords were introduced.

Usage Guidelines

  • The request for digital signal processor (DSP) statistics is controlled by the RTP Control Protocol (RTCP) statistics polling interval. The polling interval is configurable by entering the ip rtcp report interval command. Statistics are polled every 5 seconds by default.


Note

The Cisco PGW 2200 must have a patch the supports DSP statistics in order to collect data in the call detail records (CDRs).

  • This command does not generate any output on the console; it adds additional quality statistics parameters in the MGCP Delete Connection (DLCX) ACK message that is sent to the call agent.

Cisco IOS Release 12.4(4)T supports only priority levels 1 and 2.

  • The keyword priority uses a value of 1 or 2 to indicate the priority of the parameters.


Note

Choosing priority 2 is similar to using the keyword all where all the paramters are selected.

The corresponding set of VQ parameters are sent in the MGCP DLCX message based on the priority selected.

Examples

The following example enables voice-quality statistics reporting for MGCP: 


Router> enable
Router# configure terminal
Router(config)# mgcp voice-quality-stats 
Router(config)# end

The following example shows the VQ parameters selected for priority 1:

Syntax Description

passthru media-change

Passes SIP messages that involve media-change from one IP leg to another IP leg.

block

Blocks all SIP messages during mid-call.

preserve-codec

Preserves codec that is negotiated during call initialization. Mid-call codec change is disabled.

Cisco IOS XE Cupertino 17.7.1a

Introduced support for YANG models.

Usage Guidelines

The midcall-signaling command distinguishes between the way Cisco Unified Communications Express and Cisco Unified Border Element handle signaling messages. Most SIP-to-SIP video and SIP-to-SIP reinvite based supplementary services require the midcall-signaling command to be configured before configuring other supplementary services. Supplementary service features that are functional without configuring midcall-signaling include: session refresh, fax, and refer-based supplementary services. The midcall-signaling command is for SIP-to-SIP calls only. All other calls (H323-to-SIP, and H323-to-H323) do not require the midcall-signaling command be configured. The allow-connections sip-to-sip command must be configured before the midcall-signaling command.

Configuring the Session Refresh with Reinvites feature on a dial-peer basis is not supported.

Examples

The following example shows SIP messages that are configured to passthrough from one IP leg to another IP leg: 


Router(config)#voice service voip
Router(conf-voi-serv)# sip
Router(conf-serv-sip)# midcall-signaling passthru

The following example shows SIP messages that are configured to media passthru from one IP leg to another IP leg: 


Router(config)#voice service voip
Router(conf-voi-serv)# sip
Router(conf-serv-sip)# midcall-signaling passthru media-change

The following example shows how to block SIP messages. 


Router(config)#voice service voip
Router(conf-voi-serv)# sip
Router(conf-serv-sip)# midcall-signaling block

The following example shows how to disable codec negotiation in the middle of a call and retains the codec that is negotiated at the start of the call. 


Router(config)#voice service voip
Router(conf-voi-serv)# sip
Router(conf-serv-sip)# midcall-signaling preserve-codec

The following example shows SIP messages that are configured to pass thru from one IP leg to another IP leg in the voice class tenant configuration mode:

15.1(2)T

This command was modified. The session-expires keyword was added.

Cisco IOS XE Cupertino 17.7.1a

Introduced support for YANG models.

Usage Guidelines

A proxy, user-agent client, and user-agent server can all have a configured minimum value indicating the smallest session interval that they accept. If they all happen to have a different configured minimum value, the highest minimum value is used. This command sets the minimum timer that is conveyed in the Min-SE header in the initial INVITE request.

The recommended value for this command is 1800 seconds (30 minutes), which is the default value. The value cannot be set below 90 seconds because excessive INVITEs create problems for routers. Once set, the value affects all calls that are originated by the router.

If you do not configure the session expires interval and configure only the min-se value, then the session expires interval takes the value that is configured for the min-se.

Examples

The following example sets the expiration timer to 90 seconds: 


Router(config)# voice service voip
Router(conf-voi-serv)# sip
Router(conf-serv-sip)# min-se 90 session-expires 1800

12.2(8)T

This command was implemented on the following platforms: Cisco 1751, Cisco 2600 series, Cisco 3600 series, Cisco 3725, and Cisco 3745.

Usage Guidelines

Normally, when AAA is being used for simple user authentication, AAA uses the username information defined in the user profile for authentication. With store-and-forward fax, you can specify that the ANI, DNIS, gateway ID, redialer ID, or redialer DNIS be used to identify the user for authentication. This command defines what AAA uses for the primary identifier for inbound or on-ramp user authentication with store-and-forward fax.

Store-and-forward fax allows you to define either a primary or a secondary identifier. You configure the secondary identifier using the mmoip aaa receive -id secondary command.

AAA does not use these methods sequentially. If the primary identifier is defined and AAA cannot authenticate the primary identifier information, it does not use the secondary identifier for authentication. Authentication simply fails.

Defining only the secondary identifier enables you to service two different scenarios simultaneously--for example, if you are offering fax services to two different companies, one of which uses redialers and the other does not. In this case, configure the mmoip aaa receive -id primary command to use the redialer DNIS, and configure the mmoip aaa receive -id secondary command to use ANI. With this configuration, when a user dials in and the redialer DNIS is not null, the redialer DNIS is used as the authentication identifier. If a user dials in and the redialer DNIS is null, ANI is used as the authentication identifier.

This command applies to on-ramp store-and-forward fax functions.

Command

Description

aaa authentication

Enables AAA accounting of requested services for billing or security purposes when you use RADIUS or TACACS+.

mmoip aaa method fax authentication

Defines the name of the method list to be used for AAA authentication with store-and-forward fax.

mmoip aaa send-id primary

To specify the primary location where the authentication, authorization, and accounting (AAA) protocol retrieves its account identification information for off-ramp faxing, use the mmoip aaa send -id primary command in global configuration mode. To remove the definition of the account identification source, use the no form of this command.

mmoip aaa send-id primary {account-id | envelope-from | envelope-to | gateway}

no mmoip aaa send-id primary {account-id | envelope-from | envelope-to | gateway}

Syntax Description

account -id

AAA uses the account username from the originating fax-mail system as the AAA account identifier. This means that the off-ramp gateway uses the account identifier in the X-account ID field of the e-mail header. Using this attribute offers end-to-end authentication and accounting tracking.

envelope -from

AAA uses the account username from the fax-mail header as the AAA account identifier.

envelope -to

AAA uses the recipient derived from the fax-mail header as the AAA account identifier.

gateway

AAA uses the router-specific name derived from the host name and domain name as the AAA account identifier, displayed in the following format: router-name.domain-name .

Command Default

No account identification source is defined

12.1(1)T

This command was integrated into Cisco IOS Release 12.1(1)T.

12.2(4)T

This command was implemented on the Cisco 1750.

Usage Guidelines

Normally, when AAA is being used for simple user authentication, AAA uses the username information defined in the user profile for authentication. With store-and-forward fax, you can specify that the account ID, username, or recipient name from the e-mail header information be used to identify the user for authentication. This command defines what AAA uses for the primary identifier for outbound or off-ramp user authentication with store-and-forward fax.

Store-and-forward fax allows you to define either a primary or a secondary identifier. You configure the secondary identifier using the mmoip aaa send -id secondary command. AAA extracts the authentication identifier information from the defined sources. If the field is blank (meaning undefined), AAA uses the secondary identifier source if configured. The secondary identifier is used only when the primary identifier is null. In this case, when AAA sees that the primary identifier is null, it checks to see if a secondary identifier has been defined and use that value for user authentication.

AAA does not use these methods sequentially--meaning that if the primary identifier is defined and AAA cannot authenticate the primary identifier information, it does not use the secondary identifier for authentication. Authentication simply fails.

When you enable authentication, the on-ramp gateway inserts whatever value you configure for the mmoip aaa receive -id primary command in the X-account ID field of the e-mail header. This X-account ID field contains the value that is used for authentication and accounting by the on-ramp gateway. For example, if the mmoip aaa receive -id primary command is set to gateway , the on-ramp gateway name (for example, hostname.domain-name) is inserted in the X-account ID field of the e-mail header of the fax-mail message.

If you want to use this configured gateway value in the X-account ID field, you must configure the mmoip aaa send -id primary command with the account -id keyword. This particular keyword enables store-and-forward fax to generate end-to-end authentication and accounting tracking records. If you do not enable authentication on the on-ramp gateway, the X-account ID field is left blank.

This command applies to off-ramp store-and-forward fax functions.

Examples

The following example specifies the recipient name as defined in the envelope-to field of the e-mail header to be used as the AAA authentication identifier for store-and-forward fax: 


aaa new-model
mmoip aaa send-id primary envelope-to

AAA does not use these methods sequentially--meaning that if the primary identifier is defined and AAA cannot match the primary identifier information, it does not use the secondary identifier for authentication. Authentication simply fails.

When you enable authentication, the on-ramp gateway inserts whatever value you configure for the mmoip aaa receive -id secondary command in the X-account ID field of the e-mail header (if store-and-forward fax uses the defined secondary identifier). This X-account ID field contains the value that is used for authentication and accounting by the on-ramp gateway. For example, if the mmoip aaa receive -id secondary command is set to gateway , the on-ramp gateway name (for example, hostname.domain-name) is inserted in the X-account ID field of the e-mail header of the fax-mail message.

If you want to use this configured gateway value in the X-account ID field, you must configure the mmoip aaa send -id secondary command with the account -id keyword. This particular keyword enables store-and-forward fax to generate end-to-end authentication and accounting tracking records. If you do not enable authentication on the on-ramp gateway, the X-account ID field is left blank.

This command applies to off-ramp store-and-forward fax functions.

Examples

The following example specifies the recipient name as defined in the envelope-to field of the e-mail header to be used as the AAA authentication identifier for store-and-forward fax:
