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.
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.
Hi everyone. Apologies for late reply...have been busy on priojects.
Many thnaks to everyone's replies adn sorry i did not get to read all, but I have found the resolution to this issue. FYI, please see a snapshot of relevant config on SIP Gateway as beliow:-
!voice service voip clid network-provided qsig decode address-hiding allow-connections sip to sip fax protocol pass-through g711alaw sip bind control source-interface Loopback0 bind media source-interface Loopback0 header-passing asserted-id pai!interface Serial0/1/0:15 no ip address encapsulation hdlc isdn switch-type primary-qsig isdn timer T310 120000 isdn overlap-receiving isdn protocol-emulate network isdn incoming-voice voice isdn supp-service name calling profile Network-Extension operation-value-tag local isdn send-alerting isdn sending-complete isdn outgoing ie facility isdn outgoing ie extended-facility isdn outgoing display-ie isdn outgoing ie caller-number isdn outgoing ie called-number trunk-group TG-2nd-QSIG-PAIR 1 no cdp enable!
Theimportnat information in this case to make name passing work are the lines mentioning ie. Hope this helps others with same issues.
Many thnaks again.
