Hello,

are you proxying the media stream all the time now? Or just when the one 
of the party is behind the nat? I have in mynd the sceanrio when the 
initial callee is behind nat, it sends back redirect, and the new 
destination is public...

Cheers,
Daniel

  Hello,

 as i see in your failure route you close mediaproxy nat handling -- try
 to keep it on. ALso, the contacts in redirect message might be natted
 even when initial destination wasn't -- you have to deal with this case
 as well (start nat handling).

 Cheers,
 Daniel

  Hi Daniel,

 by using the following code in the failure_route block, i am able to
 have a better accounting record for billing. However, i am having one
 way audio problem which i believe it is related to NAT. I have tested
 forward a call on a UA which is on public ip, which works prefectly.
 However, when i tested it with UA which is behind NAT, one way audio
 happen when the UA send 302 reply to forward a call..

 failure_route[1]
 {
       end_media_session();
       # Handle 302 Redirects
       if (t_check_status("302")) {
               get_redirects("*");
               t_relay();
       };
 }

 Anyone has an idea on how i can fix this?

 Regards,
 Howard
