Configuring MGCP CAS MD Package

This chapter provides information on configuring the MGCP channel-associated signaling (CAS) MD Package feature. This feature introduces support for Feature Group D (FGD) Exchange Access North American (EANA) protocol signaling. The CAS MD package adds support for the reporting of automatic number identification (ANI) and dialed number identification service (DNIS) digits to enable the MGCP call agent to better handle customer billing.

For more information about this and related Cisco IOS voice features, see the following:

Information About MGCP CAS MD Package

MD Package

The MD package supports the FGD EANA protocol for T1 CAS interfaces as defined in RFC 3064. It includes support for ANI and DNIS reporting that enables the MGCP call agent to improve its handling of customer billing. The MD package is enabled automatically when a T1 interface is configured using the ds0-group command with the fgd-eana keyword. The order in which the voice gateway sends the ANI and DNIS digits can be controlled by using the notify command in the MGCP profile.

How to Configure the MGCP CAS MD Package


Note

You do not have to enable the CAS MD package with the mgcp package-capability command. The CAS MD package is enabled automatically when a T1 controller is configured for FGD EANA signaling using the ds0-group command.

Configuring the Incoming Called Number in the MGCP Dial Peer

Perform this procedure to specify the dial string to use for matching incoming calls to the MGCP dial peer.

SUMMARY STEPS

  1. enable
  2. configure terminal
  3. dial-peer voice tag pots
  4. service mgcpapp
  5. incoming called number string
  6. port port
  7. end

DETAILED STEPS

  Command or Action Purpose
Step 1

enable

Example:


Router> enable

Enables privileged EXEC mode.

  • Enter your password if prompted.

Step 2

configure terminal

Example:


Router# configure terminal

Enters global configuration mode.

Step 3

dial-peer voice tag pots

Example:


Router(config)# dial-peer voice 1003 pots

Defines a dial peer as a POTS device and enters dial-peer configuration mode.

Step 4

service mgcpapp

Example:


Router(config-dial-peer)# service mgcpapp

Enables MGCP on the dial peer.

Note 

Do not use this command in dial peers that support PRI backhaul or BRI backhaul.

Step 5

incoming called number string

Example:


Router(config-dial-peer)# incoming called number .

Specifies the digit string that is used to match incoming calls to the dial peer.

Step 6

port port

Example:


Router(config-dial-peer)# port 0/0:3:0

Binds the MGCP application to the specified voice port.

Step 7

end

Example:


Router(config-dial-peer)# end

Exits to privileged EXEC mode.

Modifying ANI and DNIS Order when Using CAS MD Package

Perform this procedure to specify the order in which ANI and DNIS digits are sent in notify messages to the call agent when using the CAS MD package.

SUMMARY STEPS

  1. enable
  2. configure terminal
  3. mgcp profile {profile-name | default }
  4. notify {ani-dnis | dnis-ani }
  5. end
  6. show mgcp profile [profile-name ]

DETAILED STEPS

  Command or Action Purpose
Step 1

enable

Example:


Router> enable

Enables privileged EXEC mode.

  • Enter your password if prompted.

Step 2

configure terminal

Example:


Router# configure terminal

Enters global configuration mode.

Step 3

mgcp profile {profile-name | default }

Example:


Router(config)# mgcp profile default

Defines an MGCP profile to be associated with one or more MGCP endpoints.

Step 4

notify {ani-dnis | dnis-ani }

Example:


Router(config-mgcp-profile)# notify dnis-ani

Specifies the order in which ANI and DNIS digits are reported to the MGCP call agent.

  • ani-dnis --ANI digits are sent in the first notify message. This is the default order.

  • dnis-ani --DNIS digits are sent in the first notify message.

Step 5

end

Example:


Router(config-mgcp-profile)# end

Exits to privileged EXEC mode.

Step 6

show mgcp profile [profile-name ]

Example:


Router# show mgcp profile default

Displays configuration information for MGCP profiles including the setting of the notify command.
