Hey everyone,
When I'm doing sequential forking I'm seeing that for each gateway that doesn't answer and I move forward
in the list of available gateways to forward the INVITE to, openser adds an "a=nortpproxy:yes" into the SDP
so what happens is that the final gateway which is alive receives the sip header with multiple lines
of "a=nortpproxy:yes" repeating themselves in the SDP and throws away the packet.
From my browsing in nathelper's code I see the only place that writes a "a=nortpproxy:yes" string to
the SDP is the fix_nated_sdp function, and I'm actually not using it in my cfg but rather using
fix_nated_register and fix_nated_contact which from what the README says are not handling
the SDP part.
And so I'm asking, where could it be coming from?
And also, it would be easier if I can insert a piece of code that can do some regular expression
miracles with the SIP header and remove any duplicate lines of the "nortpproxy" string.
I'm running on openser 1.1.1
Thanks,
Lir.
