Re [Serusers] Contact Header and SDP not rewritten

Greger, Since fix_nated_register does not exist with 0.8.14, will fix_nated_contact do instead? Also if I am leaving out the has_totag() at the start of the script, will this greatly effect its functionality? Thank you, Vivienne "Greger V.

Try using fix_nated_sdp("1"). It should make the INVITE correct. You have not posted the OK, so I don't know what is happening there. If you have followed the rtpproxy ONsip.org example in your onreply_route, you should be fine.
