Hi,

I was wondering if someone could please cast their eyes over the register sent from one of my phones behind a nat and the 200 OK sent back from SER.

There has been an issue with no audio between a natted client and a public client. I looked at the invite and noticed the private address was being used in the Contact header field and the c field in the sdp so obviously the headers are not being rewritten properly....I then checked the register messages to see if the phone was registering correctly - The message sequence is below. I notice the private header is shown but that would probably be correct seeing fix_nated_register doesnt actually change the header, it simply adds fields, is that right? i.e. thats why it replaced fix_nated-contact to be more RFC compliant

Anyway its the contact header fields sent back in the 200OK that I would like verified - Should the private address be listed as one of the options here?

I have gone back to the onsip feature callfwd script using mediaproxy to eliminate any errors due to changes I may have made The ONLY difference between the scripts is that I have

if(uri != myself) { route(4); route(1); break; };

instead of

#if (!is_uri_host_local()) { # if (is_from_local() || allow_trusted()) { # route(4); # route(1); # } else { # sl_send_reply("403", "Forbidden"); # }; # break; # };

as otherwise the phones wouldn't register.

Many thanks, Aisling.
