Hello SER users!
I am really struggling to get T.38 fax working when the UA (Sipura SPA 2000) is behind a firewall. My normal methods of employing nathelper and rtpproxy have proven fruitless.
I think one of the issues is that the receiving gateway sends a reinvite back to SER; two in fact. I'm not sure I'm handling them properly.
Has anyone have a sample config that is working for this dilemna? I'd sure appreciate a visual pointer or two.
Thanks, Jac
