MGCP Registration issue..unable to configure isdn bind-l3 ccm-manaer

Unanswered Question

Guys,

I am having an issue with mgcp registration.

On the serial port..I am unable to configure the isdn bind-l3 ccm-manager command. The iso version is

c3845-spservicesk9-mz.124-15.T5.bin.

All that is available is isdn bind-l3 q931/q921.

When I issue a sh ccm-manager, the gateway shows evrything as registered.

The output of sh ccm-manager is below

OCVG01#sh ccm-manager

Also a debug mgcp packet gives me a response code of 200..which shows evrything is fine...

However On callmanager the status shows as unregistered.

The setup is as follows

CCM--3845VG--qsig--PBX.

When I used h.323 on the gateway evrything works.

Here is a the mgcp config

ccm-manager redundant-host 10.34.161.161

ccm-manager mgcp

ccm-manager music-on-hold

ccm-manager config server 10.34.161.161

!

mgcp

mgcp call-agent 10.128.250.128 service-type mgcp version 0.1

mgcp dtmf-relay voip codec all mode out-of-band

mgcp bind control source-interface Loopback0

mgcp bind media source-interface Loopback0

!

mgcp profile default

interface Serial0/0/0:15

no ip address

encapsulation hdlc

isdn switch-type primary-qsig

isdn overlap-receiving

isdn incoming-voice voice

isdn contiguous-bchan

no cdp enable

I have this problem too.
