[Freeswitch-users] Require Timer on re-invite from FS to A-LEG

It's Wong to not accept it. IIRC...there is a better case for why it should
be there than for it not being there.  It's a rather dumb thing for some of
these commercial switches to even care about....I don't want to set a
precedence here that I will perpetually change our sip stack and chase
after every interop case... Make sure the param is set, I believe it
disables it completely going against the rfc but I can't check till
Monday.  This is part of Sofia not FS itself.
