I just read the "ser status update" from jiri and he wrote in the "new features" section:

- 3261-alignment: support for TCP and loose-routing

So I think this will be fixed in the next release?

Hello!

I've installed ser (sip:obelix.ict.tuwien.ac.at) und want'ed to use it with linphone, so I configured linphone to use ser as outbound proxy and registrar. The registration works fine but not the INVITEs. ser answers to an INVITE from linphone with a 404 Not Found and I found out that the problem is the "Route" header in the INVITE from linphone.

Route: sip:obelix.ict.tuwien.ac.at;lr

When I remove the header from the invite and send it manually (sipsak) the ser proxy accepts the invite and forwards it. I think ser reacts wrong because if an RFC3261 proxy gets an request with a route header which points to itself it should remove the header and forward the request.

Than I tried the same with an different proxy in the route header:

Route: sip:iptel.org;lr

Now, my ser proxy (sip:obelix.ict.tuwien.ac.at) accepts the request and forwards it to iptel.org, but it rewrites the invite to: INVITE sip:iptel.org;lr SIP/2.0

Thats what an RFC2543 proxy would do, but not an RFC3261 proxy, which only is allowed to do that if the route header has no "lr" parameter or if he is responsible for the domain in the request URI. If there is an "lr" parameter the proxy must not change the request URI.

If I'm wrong please let me know.

I use ser 0.8.10 with the standard config file and linphone 0.9.1 & 0.10.0
