[Freeswitch-users] Re-invite Glare issue - FS ending call

[Jason Bedward]

My provider is sending the reinvite on the A leg FS the sends this on to
the B leg. At same time the B leg provider sends a reinvite.

I dont believe FS is sending the reinvite on its own accord. Its only
because of the A leg and that we are using bypass media. So I dont think
session timers will make a difference.

FYI A leg and B leg provider are the same company although different
servers.
