Hello.
Have a problem with some uplinks. They sometimes respond "100 Trying" on
initial INVITE and... that's all. A caller waits for about 30 seconds
and cancel a call deciding there's something wrong with our network. How
to use failure route when 180/183 answers don't arrive in 5 or 10
seconds after INVITE?
