Hello,
using ser 0.9.6
The following dialog is a re-invite, the re-invite is initiated by the
callee after putting the call on hold.
Problem is that SER answer with a 407 on the wrong port, Invite is
coming from port 62907 and SER answer to port 5060.
Problem doesn't occurs for the initial invite.
We have tried with other Uas without problems, just having problems with
this Ua (Avaya).
Any idea?
Best regards,
Olivier

Hello,
I think that you can solve the problem, by putting the NAT traversal check
before the 'authentication block' where you handle the RE-INVITEs.
I use 'nathelper's module functions' :
if (nat_uac_test("27")) {
# Check flags: (1,2,8,16)
setflag(7);
force_rport();
fix_nated_contact();
fix_nated_sdp("3");
};
if (!radius_proxy_authorize("yourdomain.com")) {
proxy_challenge("yourdomain.com", "0");
break;
};
Hope this helps.
