[Freeswitch-users] session timer - enable/disable per call

AFAIK it's negotiated session timers before hitting the dialplan so you
couldn't do that without significant changes to FS.

Can you run two sofia profiles on different ports with and without timers?
You could get the vendor to use the profile with timers disabled. If they
follow it you might be able to redirect them in dialplan from one profile
to the other on a call-by-call basis.
