Hi,
We have a Cisco Call Manager (3.3) integrated with a Nortel Meridian PABX. The users from the Cisco Call Manager can call extensions in the Nortel PABX using the access code 2.
The call is established and the Nortel phones ring, but the issue no voice is recieved on both sides.
Im not very experienced with Voice and not sure where to start troubleshooting.
I have collected the debugging for: debug h245 asn1 (attached)
The integration was done through a Voice Gateway (Cisco 3745)
You can also find output for show isdn status below while the call is estabilshed:
Vsat-Router#sho isdn sta
Vsat-Router#sho isdn status
Global ISDN Switchtype = primary-qsig
ISDN Serial4/0:15 interface
dsl 0, interface ISDN Switchtype = primary-qsig
**** Slave side configuration ****
Layer 1 Status:
ACTIVE
Layer 2 Status:
TEI = 0, Ces = 1, SAPI = 0, State = MULTIPLE_FRAME_ESTABLISHED
Layer 3 Status:
1 Active Layer 3 Call(s)
CCB:callid=8089, sapi=0, ces=0, B-chan=31, calltype=VOICE
Active dsl 0 CCBs = 1
The Free Channel Mask: 0xBFFF7FFF
Number of L2 Discards = 0, L2 Session ID = 10
Thanks

HI,
We have document which shows CUCM and Nortel Meridian using E1 QSIG.
http://www.cisco.com/en/US/docs/voice_ip_comm/cucme/pbx/interop/notes/431470nt.pdf
Compare your configuration with the document and see if you have missed anything.
