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.
