So you have two UA's using Sofia-SIP, one (A) registers from NATted network and another one (B) calls outside through the registrar/proxy. When B sends an INVITE to A, the proxy uses correctly the connection incoming from UA A for outbound INVITE. However, the ACK and BYE requests sent by UA B within dialog are routed directly to the Contact address given by A? > Is there any known solution to this problem?

(A copies Record-Route to the response, and B uses the Record-Route URI when sending the ACK and BYE.) The proxy should also map the incoming ACK/BYE to the A's connection somehow (it can use methods described in draft-ietf-sip-outbound, for instance). -- Pekka.Pessi mail at nokia.com ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
