Prerequisites for LPCOR

  • Cisco IOS Release 15.0(1)XA or a later release.

  • Cisco Unified CME 8.0 or a later version.

Information About LPCOR

LPCOR Overview

The Telecom Regulatory Authority of India (TRAI) has regulations that restrict the mixing of voice traffic between the PSTN and VoIP networks. Previously, this required a user to have two phones to handle both PSTN and VoIP calls; an IP phone connected to the Electronic Private Automatic Branch Exchange (EPABX) for intra-office and inter-office VoIP calls and a separate phone connected to a PABX for PSTN calls, as shown in Separate PBX and EPABX Systems.

New regulations allow for a single network infrastructure and single EPABX to connect to both the PSTN and VoIP networks by using a logical partitioning between the PSTN and IP leased lines.

The logical partitioning class of restriction (LPCOR) feature enables a single directory number on an IP phone or analog phone registered to Cisco Unified CME to connect to both PSTN and VoIP calls according to the connection restrictions specified by TRAI regulations. Cisco Unified CME can support both VoIP and PSTN calls while restricting the mixing of voice traffic between the PSTN and VoIP networks and preventing PSTN calls from connecting to remote locations over an IP trunk, as shown in Single EPAPX System with PSTN and VoIP Calls Partitioning.

LPCOR Policy and Resource Groups

Cisco Unified CME supports a high-level class of restriction by allowing you to logically partition its resources (PSTN trunks, IP trunks, IP phones, and analog phones) into different groups. The resources of each group are scalable based on the voice interface, trunk group, or IP address subnet. In general, you should not have to modify your existing dial plan to support LPCOR functionality. The dial peer class of restriction (COR) feature remains unchanged when the LPCOR feature is added to Cisco Unified CME.

LPCOR control is based on the location of resources, where calls are originating and terminating. You must partition the resources of the Cisco Unified CME router into different resource groups and then create a LPCOR policy for each group to which you want to apply call restrictions.

You create a LPCOR policy matrix for individual resource groups by defining its LPCOR policy to either accept or reject calls that originate from any of the other resource groups. You can define one LPCOR policy for each resource group.

The same LPCOR policy is applied to multiple directory numbers from the same resource. For example, if multiple directory numbers are defined for a SCCP phone, the same LPCOR policy is enforced for all calls to the different directory numbers on the SCCP phone.

In the following example, PSTN trunks, IP trunks (H.323 and SIP), analog FXS phones, and IP phones for a Cisco Unified CME router are partitioned into five different resource groups (RG1 to RG5).

LPCOR validation is done at the target destination based on the configured LPCOR policy matrix. For example:

  • Call from RG1 to target RG1 is allowed

  • Call from RG2 to target RG3 is not allowed

  • Call from RG3 to target RG2 is allowed

  • Call from RG5 to target RG5 is not allowed

Default LPCOR Policy

The default LPCOR policy means that there are no restrictions between the call source and its target destination. When a call is presented to a target destination, Cisco Unified CME bypasses LPCOR validation if either the incoming call is not associated with a LPCOR policy or the LPCOR policy is not defined for the target destination.

TRAI regulations allow the same directory number on a local IP phone or SCCP analog Foreign Exchange Station (FXS) phone in Cisco Unified CME to handle both PSTN and VoIP calls. Locally connected phones do not have to be associated with any resource group.

How LPCOR Policies are Associated with Resource Groups

Call restrictions are applied to LPCOR resource groups based on the location of the resources. You create LPCOR policies that define the call restrictions to apply to calls that originate or terminate at the following types of resources.

Analog Phones

TRAI regulations allow an analog FXS phone to accept both PSTN and VoIP calls if the phone is locally registered to Cisco Unified CME. Locally connected phones do not have to be associated with any resource group; the default LPCOR policy is applied to this phone type.

A specific LPCOR policy can be defined through the voice port or trunk group. For configuration information, see Associate a LPCOR Policy with Analog Phone or PSTN Trunk Calls.

IP Phones

LPCOR supports both SCCP and SIP IP phones. TRAI regulations allow an IP phone to accept both PSTN and VoIP calls if the IP phone is registered locally to Cisco Unified CME through the LAN. If the IP phone is registered to Cisco Unified CME through the WAN, PSTN calls must be blocked from the remote IP phones.

If an IP phone always registers to Cisco Unified CME from the same local or remote region, the phone is provisioned with a static LPCOR policy. For configuration information, see Associate a LPCOR Policy with IP Phone or SCCP FXS Phone Calls.

If the phone is a mobile-type IP phone and moves between the local and remote regions, such as an Extension Mobility phone, Cisco IP Communicator softphone, or a remote teleworker phone, the LPCOR policy is provisioned dynamically based on the IP phone’s currently registered IP address. For configuration information, see Associate LPCOR with Mobile Phone Calls.

PSTN Trunks

An incoming LPCOR resource group is associated with a PSTN trunk (digital or analog) through the voice port or trunk group.

When a call is routed to the PSTN network, the LPCOR policy of the target PSTN trunk can block calls from any resource group it is not explicitly configured to accept. Outgoing calls from a PSTN trunk are associated with a LPCOR policy based on either the voice port or trunk group, whichever is configured in the outbound POTS dial-peer.

For configuration information, see Associate a LPCOR Policy with Analog Phone or PSTN Trunk Calls.

VoIP Trunks

An incoming VoIP trunk call (H.323 or SIP) is associated with a LPCOR policy based on the remote IP address as follows:

Incoming H.323 trunk call

  • IP address of the previous hub or originating gateway

Incoming SIP trunk call

  • IP address of the originating gateway

  • Hostname from the earliest Via header of an incoming INVITE message. If the hostname is in domain name format, a DNS query is performed to resolve the name into an IP address.

Cisco Unified CME uses the resolved hostname or resolved IP address to determine the LPCOR policy based on the entries in the IP-trunk subnet table. If the LPCOR policy cannot be found through the IP address or hostname, the incoming H.323 or SIP trunk call is associated with the incoming LPCOR policy configured in voice service configuration mode.

The LPCOR policy of the VoIP target is determined through the configuration of the outbound VoIP dial-peer. The default LPCOR policy is applied to the VoIP target if an outgoing LPCOR policy is not defined in the target VoIP dial-peer.

For configuration information, see Associate a LPCOR Policy with VoIP Trunk Calls.

LPCOR Support for Supplementary Services

Table 1 describes LPCOR support for calls using supplementary services.

Feature

Description

SCCP Phone

SIP Phone

Basic Call

Cisco Unified CME invokes the LPCOR policy validation if both the incoming call and target destination are associated with a LPCOR policy.

If the LPCOR policy validation fails, cause-code 63 (no service available) or the user-defined cause-code is returned to the remote switch. The call can hunt to the next destination.

Yes

Yes

Call Forward

When a call is forwarded to a new destination, Cisco Unified CME invokes the LPCOR policy validation between the source and the forwarding target. The call is not forwarded to the target if the LPCOR policy is restricted.

Yes

Yes

Call Transfer

Blind and Consultative Call Transfer is restricted if the LPCOR policy validation fails between the transferee and transfer-to parties.

For consultative call transfers, the reorder tone plays and an error message displays on the transferor phone. The call is not disconnected between the transferee and transferor.

Yes

Yes

Ad Hoc Conference (software-based, 3-party)

Cisco Unified CME invokes the LPCOR policy validation for each call joined to a conference. A call is blocked from joining the conference if the LPCOR policy validation fails.

The reorder tone plays and the conference cannot complete message displays on the IP phone that initiated the conference. The call is resumed by the transferor who initiated the conference.

Note

 

If the LPCOR policy validation fails during a blind transfer setup to a conference bridge, the call is released.

Note

 

LPCOR validation is not supported for additional call transfer or conference operations from a 3-party software conference call.

Yes

No

Ad Hoc Conference (hardware-based)

Yes

Yes

Meet-Me Conference

LPCOR policy of each conference party is validated when a new call is joined to a conference. The call is blocked from joining the conference if the LPCOR policy validation fails.

The reorder tone plays and the conference cannot complete message displays on the IP phone that initiated the Meet-Me conference.

Yes

Yes (join only)

Call Pickup/Group Pickup (Cisco Unified CME 7.1 and later versions)

Call Pickup and Pickup Groups enable phone users to answer a call that is ringing on a different extension. The pickup is blocked if the LPCOR policy validation between the call and the pickup phone fails.

The reorder tone plays and the unknown number message displays on the IP phone that attempts the call pickup.

Yes

Yes

Call Park (Cisco Unified CME 7.1 and later versions)

Phone users can place a call on hold at a special extension so it can be retrieved by other phones.

A phone is not allowed to retrieve a parked call if the LPCOR policy validation fails. The reorder tone plays and the unknown number message displays on the IP phone that attempts to retrieve the parked call. The call remains parked at the call-park slot.

Yes

Yes

Call Park Retrieval

Yes

Yes

Hunt Group Pilot (ephone hunt group)

Supported for sequential and longest idle hunt groups. The LPCOR policy validation is performed when a call is directed to a SCCP endpoint through the ephone hunt-group.

Yes

No

Hunt Group Pilot (voice hunt group)

Supported for parallel hunt groups only. A hunt target can be a SCCP phone, SIP phone, VoIP trunk, or PSTN trunk. The LPCOR policy validation is performed between the call and the pilot hunt target. A call is blocked from a target if the LPCOR policy is restricted.

Yes

Yes

Shared Line

Phones with a shared directory number must have the same LPCOR policy.

Yes

Yes

CBarge

Phone users who share a directory number can join an active call on the shared line. Phones must have the same LPCOR policy.

Examples

The following example shows a LPCOR configuration where resources are partitioned into five groups. Three of the resource groups have LPCOR policies that limit the calls they can accept. The other two groups, ipphone_local and analog_phone, can accept calls from any of the other resource groups because they do not have a LPCOR policy defined. 


voice lpcor enable
voice lpcor call-block cause invalid-number
voice lpcor custom
 group 1 pstn_trunk
 group 2 analog_phone

Associate a LPCOR Policy with Analog Phone or PSTN Trunk Calls

To associate a LPCOR policy with calls that originate or terminate at an analog phone or PSTN trunk, perform the following task. You can apply a specific LPCOR policy through the voice port or trunk group to remote analog phones or to local analog phones that you do not want to associate with the default LPCOR policy.


Note

For an analog FXS phone that is locally registered to Cisco Unified CME through the LAN, see Associate a LPCOR Policy with IP Phone or SCCP FXS Phone Calls.

Incoming calls from an analog phone or PSTN trunk are associated with a LPCOR resource group based on the following configurations, in the order listed:

  1. Voice port

  2. Trunk group

Outgoing calls from an analog phone or PSTN trunk are associated with a LPCOR policy based on the voice port or trunk group configuration in the outbound POTS dial-peer:

  • If the outbound dial peer is configured with the port command, an outgoing call uses the LPCOR policy specified in the voice port.

  • If the outbound dial-peer is configured with the trunkgroup command, the call uses the LPCOR policy specified in the trunk group.

Before you begin

The LPCOR policy must be defined. See Define a LPCOR Policy.

Examples for Configuring LPCOR for a PSTN Trunk and Analog Phones

The following example shows a configuration for a PSTN trunk. Outbound calls from dial peer 201 use LPCOR policy isdn_group1 because dial peer 201 is configured with trunk group isdn1. Outbound calls from dial peer 202 use LPCOR policy vp_group3 because dial peer 202 is configured with voice port 3/1:15. A dial peer can be configured with either a voice port or trunk group; it cannot use both.

Associate a LPCOR Policy with VoIP Trunk Calls

To associate a LPCOR policy with calls that originate or terminate at a VoIP trunk (H.323 or SIP), perform the following task.

Incoming VoIP trunk calls are associated with a LPCOR policy based on the following configurations, in the order listed:

  1. IP-trunk subnet table

  2. Voice service voip configuration

Outgoing VoIP trunk calls are associated with a LPCOR policy based on the following configurations, in the order listed:

  1. Outbound VoIP dial peer

  2. Default LPCOR policy (no LPCOR policy is applied)


Restriction

  • The LPCOR IP-trunk subnet table is not supported for calls with an IPv6 address. The LPCOR policy specified with the lpcor incoming command in voice service configuration mode is supported for IPv6 trunk calls.

  • Only a single LPCOR policy is applied to outgoing IP trunk calls if the outbound VoIP dial-peer is configured with the session target command using the sip-server or ras keyword.

  • If a dial peer COR and LPCOR are both defined in a dial peer, the dial peer COR configuration has priority over LPCOR. For example, if the dial peer COR restricts the call and LPCOR allows the call, the call fails because of the dial peer COR before ever considering LPCOR.

Before you begin

The LPCOR policy must be defined. See Define a LPCOR Policy.

Associate a LPCOR Policy with IP Phone or SCCP FXS Phone Calls

To associate a LPCOR policy with calls that originate or terminate at a local or remote IP phone or local SCCP analog (FXS) phone, perform the following task.

According to TRAI requirements, an IP phone or a SCCP FXS phone can accept both PSTN and VoIP calls if it is locally registered to Cisco Unified CME through the LAN. If a phone is registered to Cisco Unified CME through the WAN, then PSTN calls must be blocked from that remote phone.


Restriction

  • Phones that share a directory number must be configured with the same LPCOR policy. A warning message displays if you try to configure a different LPCOR policy between IP phones that share the same directory number.

  • Local and remote IP phones cannot use the same LPCOR policy.

  • Software-based three-party ad hoc conferencing is not supported on SIP phones.

  • Hardware-based ad hoc conferening is not supported on SIP phones.

  • LPCOR feature is not supported on voice gateways such as the Cisco VG224 or Cisco integrated service router if the voice gateway is registered to Cisco Unified Communications Manager. Cisco Unified Communications Manager does not support LPCOR.

  • If a third-party call-control application makes two separate calls to Cisco Unified CME and performs a media bridging between the two calls, LPCOR validation is not supported because Cisco Unified CME is not aware of the bridging.

Before you begin

  • The LPCOR policy must be defined. See Define a LPCOR Policy.

  • SCCP FXS phones are configured with the type anl command.

Figure 3. SCCP FXS Phones Managed by Cisco Unified CME

Associate LPCOR with Mobile Phone Calls

To associate a LPCOR policy with calls that originate or terminate at a mobile-type phone, perform the following task.

A mobile-type phone can register to Cisco Unified CME through either the LAN or WAN. For example an Extension Mobility phone, Cisco IP Communicator softphone, or a remote teleworker phone.

Incoming and outgoing calls to and from a mobile-type phone are associated with a LPCOR policy based on the following configurations, in the order listed:

  1. IP-phone subnet table

  2. Default LPCOR policy for mobile-type phones


Restriction

The LPCOR IP-phone subnet table is not supported for calls with an IPv6 address.

Before you begin

The LPCOR policy must be defined. See Define a LPCOR Policy.

SUMMARY STEPS

  1. enable
  2. configure terminal
  3. ephone phone-tag or voice register pool phone-tag
  4. lpcor type mobile
  5. exit
  6. voice lpcor ip-phone subnet{ incoming | outgoing}
  7. index index-number lpcor-group{ ipv4-address network-mask [ vrfvrf-name] | dhcp-pool pool-name}
  8. exit
  9. voice lpcor ip-phone mobility{ incoming | outgoing} lpcor-group
  10. exit

The following example shows a LPCOR IP-phone subnet configuration with a single shared IP address pool. Any mobile-type IP phones with a shared IP address from DHCP pool1 are considered local IP phones and are associated with the local_group1 LPCOR policy. Other mobile-type IP phones without a shared IP address are considered remote IP phones and are associated with remote_group1, the default LPCOR policy for mobile-type phones. 


ip dhcp pool pool1

Configuration Examples for LPCOR

Example for Configuring LPCOR for Cisco Unified CME

LPCOR Resource Grouping in Cisco Unified CME Network shows an example of a Cisco Unified CME network using LPCOR. This network is organized into the following four LPCOR resource groups:

  • local_group—Analog and IP phones, including a mobile-type phone, connected locally to Cisco Unified CME.

  • pstn_group—Trunks between the PSTN and Cisco Unified CME.

  • remote_group—IP phones, including a mobile-type phone, and a SIP proxy server connected remotely to Cisco Unified CME through the WAN.

  • voice_mail_group—Cisco Unity Express voice-mail system connected remotely to Cisco Unified CME through the WAN.

Figure 4. LPCOR Resource Grouping in Cisco Unified CME Network
LPCOR Policy Logic illustrates the access policy between resource groups that provides the following call requirements:

  • Blocks calls between remote_group and pstn_group

  • Blocks calls from voice_mail_group to pstn_group and remote_group

  • Allows calls between local_group and remote_group

  • Allows calls between local_group and pstn_group

  • Allows all calls to voice_mail_group

Figure 5. LPCOR Policy Logic

The following output shows the LPCOR configuration for this example and describes the steps. Comments describing the configuration are included in the output.

  1. Enable LPCOR functionality in Cisco Unified CME and define custom LPCOR group. 

    
voice lpcor enable 
!
voice lpcor custom 
	group 1 pstn_group 
	group 2 local_group 
	group 3 remote_group 
	group 4 voice_mail_group 
	! 
	#Allow calls only from local group to PSTN group 
	voice lpcor policy pstn_group 
	 accept local_group 
	! 
	# Allow calls from PSTN, remote, and voice_mail groups to local group 
	voice lpcor policy local_group 
		accept pstn_group 
		accept remote_group 
		accept voice_mail_group 
	! 
	# Allow calls only from local group to remote group 
	voice lpcor policy remote_group 
		accept local_group 
	! 
	# Allow calls from PSTN, remote, and local groups to voice_mail group 
	voice lpcor voice_mail_group 
	 accept pstn_group
	 accept local_group 
	 accept remote_group 
	!
