[SR-Users] SL local ACK found -> dropping it! error ...

Wed Jan 19 19:14:35 CET 2011

Efectively it was an issue with FW. I've setup my kamailio to listen on 5060
and 5062.
Now I can call media server and my extensions can receive / make local calls
respectively.
The issue now is that I've got my SIP PSTN gateway that try to reach our
server on port 5060 and this gateway listen on 5060 too.
It shouldn't be a problem because Kamailio listen over 5060 and 5062 but
unfortunately doesn't work and send me back a 404 error code.

I use the same configuration as before just add two "listen" line

Best regards
