Hi,
We have recently configured Qsig on 2951 router and CUCM to interface between CUCM 9.1 to Tetra system using MTIG (Motorola Telephone Interconnect Gateway).
Seems the connection establish but we unable to see any Layer 2 frame exchanged Such as TEI and SPID are 0. Can anyone suggest what could be issue?
Layer 2 Status:
TEI = 0, Ces = 1, SAPI = 0, State = MULTIPLE_FRAME_ESTABLISHED
Below is the Configuration and output for review.

Hi Raj
Your configuration , and output is very well. The most important thing that MULTIPLE_FRAME_ESTABLISHED appear under L2 . A SAPI is a Service Application endPoint ID. So the fact that you show two SAPIs (0 and 1) under TEI would be driven by your equipment/configuration. Several of these probles exist on the telco switch side of things, so it's a safe start to blame them. But in the future the "debug isdn q921" will help a lot with that. For more information kindly check the below link:-

Hi Kamal,
Thank you for reply
Yes, I did debug as well but i could not any frames. Other side (Tetra MTIG) can work with other Vendor Pabx.

Hi,
Am integrating Cisco CUCM 12.5 with Radio from Motorola over MGCP gateway and I am getting the below error message for incoming calls [from Radio to Cisco IP phones] whereas the outgoing call from Cisco IP phone to Radio is working fine.
