Hi all

I do have a problem with getting a propper interconnection to our new carrier..

Situation as following

User à Class5 switch à Kamailio à carrier

I always get the ip of the class5 switch in the contact.

But my carrier needs the kamailios contact ip – because of the ack handling.

I replaced in the pstn routing parte the contact by

                remove_hf("Contact");

                append_hf("Contact: <sip:xyz@a.b.c.d>\r\n");

This worked – but the bye did not work any more.

Please help me on that topic … I am searching for a solution for more than 8 weeks now …

KR,

Oli
