Avaya Session Manager 6.3, Avaya CM 6.3, SpectraLink 8440, and an FX type Paging Trunk

[MylZhI]

Having an odd issue here with a paging trunk and some 8400's. Basically the 8400 is able to dial the TAC and we hear over head the paging tone play. On the Spectralink side however we only hear continuous ring back? Curious if someone has some insight. Trunk configs below

Post a Session Manager trace. If you can, do an MST trace in CM on your SIP trunk as well if you can - but SM might be enough for now.

To me, it seems like whatever SIP message CM is sending back to your 8400 set once you dial the TAC is not being processed properly by the 8400.

Maybe compare 8400 calling that paging trunk and 8400 calling another phone that answers, look at the last 200OK SM sends that 8400 in each scenario and you might just find there's a tweak on the sig/trunk to make the paging work for you properly.
