I am currently running opensips 1.8.1 no tls. It is multi-homed with a public and private address. I have a asterisk 1.8.19 in the lan that is connected to opensips via lan address. A caller calls in and then I place an outbound call and finally join the two. This works as expected except when the outbound caller hangs up first the BYE never gets back to Asterisk. I can see the BYE reach OpenSips but a '404 not here' is returned to the ISP.

thanks for your time.
