[reSIProcate] Why is my 606 RESPONSE discarded as stray message?


Hi!

I don't know why my message is being rejected by the stack.

I searched the mailing list and there is one message stating that In one particular case It was because the via branch parameters did not match.

However I have checked my packet capture and the only difference between the outgoing INVITE and the incoming 606 is as follows:

outgoing INVITE
Via: SIP/2.0/UDP xxx.yyy.154.36:12010;branch=z9hG4bk-d87543-b40623120ac0d246-1--d87543-;rport

incoming 606
Via: SIP/2.0/UDP xxx.yyy.154.36:12010;branch=z9hG4bk-d87543-b40623120ac0d246-1--d87543-;rport=12010

Is the small diference with rport not having a value enough to get the message discarded?

Please tell me if there are any other possible reasons for this behaviour.

Sincerely
<victor>
