Has anyone seen any weird signalling behaviour of Freeswitch when
interworking with MS Teams server?
We have seen a few weird things where freeswitch is apparently not passing
the signaling messages from one leg to the other in B2BUA mode.
In one of the weird cases, freeswitch decides to not relay the SIP Bye
message from the called party to the caller and just consumes it (resulting
in the call to stay up from the caller's side).
This has happened randomly as well as in one particular call scenario when
a feature is activated on ms teams side. However SIP signaling wise we
cannot see any difference between a good call (where SIP bye is relayed to
caller by freeswitch and the one where it decides to stomp on it).
Our freeswitch version is "FreeSWITCH (Version 1.10.5
I am not including any PCAPS or detailed configuration of freeswitch in
the post yet and can provide it if required.
Any ideas or link to some useful resources please?
