SIP connection between two Avaya CM

[Davicat]

Hello,

I'm trying to connect two avaya CM by SIP trunking, the calls work when calling from CM "A" to CM "B" but when CM "B" send the invite to CM "A" the invite does not progress.

This is the trace of the not working call:

10:01:44 TRACE STARTED 10/19/2020 CM Release String cold-03.0.124.0-21754

10:02:29 idle trunk-group 30 member 10 cid 0x18d4
10:02:32 idle station 0998 cid 0x18d4

Anyone has a idea on what could be happening?

Thanks

There could be a couple of reasons why the call from CM B to CM A is failing. Is there any incoming call handling necessary? is the trunk set for private numbering but the route set for public-unknown? You can do the standard "stare-and-compare" between the two CMs to try to spot the difference.

This looks like a trace on CM B when calling to CM A. What does a trace on CM A look like when the call fails? Try list trace tac ### for the trunk group to capture the incoming call. That should point you in the right direction.

Any reason you don't make your life easier with a QSIG H323 trunk?
