Configuring the SIP Registrar

How to Configure the SIP Registrar

Cisco Unified SIP SRST 4.0 System Administrator Guide

DETAILED STEPS

Step 1 debug voice register errors

Use this command to debug errors that happen during registration, for example:

Router# debug voice register errors

*Apr 22 11:52:54.523 PDT: VOICE_REG_POOL: Contact doesn't match any pools

*Apr 22 11:52:54.539 PDT: VOICE_REG_POOL: Register request for (33015) from (10.2.152.39)

*Apr 22 11:52:54.539 PDT: VOICE_REG_POOL: Contact doesn't match any pools.

*Apr 22 11:52:54.559 PDT: VOICE_REG_POOL: Register request for (33017) from (10.2.152.39)

*Apr 22 11:53:04.559 PDT: VOICE_REG_POOL: Maximum registration threshold for pool(3) hit

If there are no voice register pools configured for a particular registration request, the message “Contact

doesn’t match any pools” is displayed.

Step 2 debug voice register events

Using the debug voice register events command should suffice to display registration activity.

Registration activity includes matching of pools, registration creation, and automatic creation of dial

peers. For more details and error conditions, you can use the debug voice register errors command.

Router# debug voice register events

Apr 22 10:50:21.731 PDT: VOICE_REG_POOL: Contact matches pool 1

Apr 22 10:50:21.731 PDT: VOICE_REG_POOL: key(91011) contact(192.168.0.2) add to contact

table

Apr 22 10:50:21.731 PDT: VOICE_REG_POOL: key(91011) exists in contact table

Apr 22 10:50:21.731 PDT: VOICE_REG_POOL: contact(192.168.0.2) exists in contact table, ref

updated

Apr 22 10:50:21.731 PDT: VOICE_REG_POOL: Created dial-peer entry of type 1

Apr 22 10:50:21.731 PDT: VOICE_REG_POOL: Registration successful for 91011, registration

id is 257

The phone number 91011 registered successfully, and type 1 is reported in the debug, which means there

is a preexisting VoIP dial peer.

Step 3 show sip-ua status registrar

Use this command to display all the SIP endpoints currently registered with the contact address.

Router# show sip-ua status registrar

Line destination expires(sec) contact

============ =============== ============ ===============

91021 192.168.0.3 227 192.168.0.3

91011 192.168.0.2 176 192.168.0.2

95021 10.2.161.50 419 10.2.161.50

95012 10.2.161.50 419 10.2.161.50

95011 10.2.161.50 420 10.2.161.50

95500 10.2.161.50 420 10.2.161.50

94011 10.2.161.40 128 10.2.161.40

94500 10.2.161.40 129 10.2.161.40

Verifying Proxy Dial-Peer Configuration

To use the icmp-ping keyword with the proxy command to assist in troubleshooting proxy dial peers,

perform the following steps.
