Hi Franz, Sorry for the misunderstanding, none of the nodes are "local only". Its a private address that they're listening to.
As for the issue, source UE sends correct ACK with the right RURI (containing the correct IP and port of the destination UE). But P-CSCF strips that alias parameter off such that the ACK ends up going to the *wrong port* of destination UE. It seems that the proxy is not honouring the alias that was added. (same is the case with PRACK). Has anyone else experienced the same issue? I am using the default examples of kamailio pcscf git master version. -- View this message in context: http://sip-router.1086192.n5.nabble.com/Kamailio-ims-nat-issue-PRACK-ACK-ruri-changing-in-p-cscf-tp152072p152139.html Sent from the Users mailing list archive at Nabble.com. _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users@lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users
