[Asterisk-Users] sip reply sent to wrong port

[John Todd]

Juha -
   Experiment with the "insecure=1" setting under the settings for 
that SIP peer.  That setting was added recently to change the 
behavior of Asterisk in replies to SIP requests. (makes Asterisk 
reply to source port of requestor, instead of port 5060 all the time)

   However, I will note that I have seen similar problems with certain 
SIP clients in the past, especially on "BYE" requests, so your 
problem will probably not be solved with "insecure=1"  -  I'll dig 
around a little bit and experiment to see if I can produce similar 
results.
