Re: [SR-Users] BYE not forwarded

I misunderstood the reason for the domain module. I thought it was used to store (remote) domains the proxy should handle and allow. And by domains I mean remote addresses. For instance, when providing customers with a SIP trunk and the Kamailio being the proxy for those trunks and their domains. Currently the addresses contained in the table are all remote addresses. The client (10.0.0.40) was just to simulate a remote sip server sending calls. This logic is perhaps more suited for the permissions and group module am I correct?

Eventually you can add local ip addresses, but they are redundant if you just want to compare with 'myself'. You must not add in the domain table the ip addresses of client devices (phones). By adding an ip address to domain table you tell kamailio to consider the uri that has that IP as for itself. So, practically instead of forwarding to IP 10.0.0.40, you tell to kamailio to handle locally the requests with uri including 10.0.0.40. You should just remove 10.0.0.40 from domain table, I see no reason to have it there, given it is one used by a client device.

The BYE is sent back to the UAC. modparam("domain", "register_myself", 0) Not sure as to why this changes the behavior?

It looks like kamailio considers it to be a local domain.

Upon authentication the INVITE is sent to Freeswitch for further handling. Kamailio stays in the path using record-route. At this point, the authentication and calling FS works fine. For now, FS just answers, plays a file and hangsup the call. Answering the call and playing a file works fine. When FS hangs up the call, the BYE message is sent back to Kamailio. The problem is the BYE message from FS contains a Route header which points to Kamailio again. Which causes Kamailio to send the BYE message back to itself. Kamailio then replies with a 404. The BYE is never sent to the UAC. When I remove the record_route() for INVITEs, the call works fine, but Kamailio isn't kept in the signaling path. The BYE is sent directly to the UAC.
