I have an integration between a Cisco Router 2900 and a Nortel PBX CS1000M. They are both connected with an E1 R2 CAS. When we configure the E1 with no ANI request, we are able to dial from cisco to nortel and viceversa. If I enable ANI on Cisco Router and enable caller ID on Nortel call completes from Cisco to Nortel (with no caller ID on Nortel), and it does not work from Nortel to Cisco (on Nortel you just hear a beep, and channel stays on seize status). I would like Nortel extensions and Cisco extensions to ID correctly.
Cisco router is running IOS 15.1(2)T1 with UC license. Nortel PBX I know it runs firmware version 4.0. I'm attaching the output from debug voip ccapi inout, debug voip vtsp all and debug vpm signal
Extension on Cisco is 4707 and Extension on Nortel PBX is 4280
Has any of you jumped into something similar?. I'm not experienced on Nortel, and tech guy I'm working with does not understand about signaling.
Configuration on Cisco side:
controller E1 0/3/0
ds0-group 1 timeslots 1-15,17-30 type r2-digital r2-compelled ani
country telmex use-defaults
answer-signal group-b 1

The Cisco Interoperability Portal will get you where you need to go. Just a side-note with my recent experience with the Nortel CS1000M running V3 software the Nortel PBX cannot do NI2 as a Tie Line for OnNet calling. You can however do a DMS100 as a Tie Line for OnNet calling which will give you better Caller ID services. If you can I would suggest a QSIG PRI but that requires an MGCP gateway so if you are running any integrations that do not support MGCP you'll want to go the DMS100 route. Also, I would recommend integrating with SIP into CUCM if you are on a release higher than 6.1.
Any possibility you set the PBX for PRI ?
That will make everythign work easy and smooth.
Troubleshooting E1 R2 is always an arduous task. It requires a lot of skills, time, equipment. It should really be avoided if possible at all.
