[OpenSIPS-Users] Strange retrasmission of bye messages

[Giuseppe Roberti]

Hi,
maybe its my misconfiguration (or misunderstood), it resend the BYE for
every 200 Ok reply from the gateway.
I have tried to send again 200 Ok from the gateway for every received
BYE so it look like:

1) UAC => BYE => OPENSIPS
2) OPENSIPS => BYE => GW
3) GW => 200 => OPENSIPS
4) OPENSIPS => BYE => GW
5) GW => 200 => OPENSIPS
6) OPENSIPS => BYE => GW
7) GW => 200 => OPENSIPS
.. and so on ..

The full log can be found on http://rafb.net/p/ltV7wd57.html

Thanks.
