Caller Name display - CUCM->SIP Gateway<->Nortel CS1000M PBX

Hi there. We have the following configured:-

- CUCM version 7.1

- Cisco IP Endpoint

- Cisco SIP Gateway

- Nortel CS1000M PBX

- Nortel Endpoint

- QSIG between Cisco SIP Gateway and Nortel CS1000M

when making calls betweent the Nortel endpoint and the Cisco Endpoints we don't get name displayed between the devices. Anyone know what is required for this to take place?

All help is hugely appreciated. :-)

On the VG, take "debug isdn q931" with "term mon".

Do not take any other debug for now. Do not use file attachments, just paste the output here.

Mark,

It typically best to use MGCP to integrate between a Nortel PBX, connected via QSIG ISDN T1, to a CUCM. This may be a limitation of tunneling QSIG over SIP to CUCM.

Is there a particular reason to that is causing you to use SIP?

Can you attach the running configuration and collect the following debugs.

debug ccsip message

debug voip ccapi inout

debug isdn q931

Please note the calling and called party numbers as well as the CLID name that should have been sent.
