FYI,
I've been examining the protocol going back and forth Between proxy and remote sip gateway. Always I see 2 INVITE messages before the first response. I increased timeouts...
modparam("tm","retr_timer1p1", 2) # increase retry timeout modparam("tm","retr_timer1p2", 3) # increase retry timeout modparam("tm","retr_timer1p3", 6) # increase retry timeout
And I don't see the 'bounce' any more.
