Hi ,
i am facing the same problem, can advice where you add the t_on_reply("1")
to make the PSTN have audio.
I have another problem I want to send public address instead of NAT address
in the c=IP4 function in the SDP message, anyone done this before, i am a
newbie I am problem in trying to code it. Please help. Thanks in
advance.....
Regards,
nicky
