[OpenSIPS-Users] Continously ringing

[Liviu Chircu]

Make a SIP trace with *sngrep *program and check the routing of the 486 
Busy / 603 Decline message sent by phone B.  If A is still in ringing, 
it most likely means the reply isn't reaching it.

It is possible phone A is behind a NAT and its /Via/ SIP header needs a 
small adjustment for the replies to be properly routed back, using this 
useful /opensips.cfg/ function call:

force_rport()
