Hi

Thanks in advanced if anyone can help me on this.

I have kamailio -4.2.3-1.1 running in front of asterisk  13.13.1. I’m using Path support with asterisk so that I can forward Sip requests via kamailio to the asterisk server running on a LAN IP. Kamailio is configured with a WAN and LAN IP.

All works well I can register a sip endpoint to the asterisk server via kamailio and make an receive calls, SIP OPTIONs from the asterisk server are received and relayed by kamailio to endpoints.  But I’m having issues when a call is hung up asterisk appears to be trying to send the BYE via its own IP address rather that the IP of the LAN interface on the kamailio server.

Should I be looking at the issue being on asterisk as it is not sending the BYE via correct IP?

Y.Y.Y.Y = WAN IP of client endpoint

192.10.10.216 = LAN IP of asterisk
