????: Re: [pjsip] Wrong NAT detection results
I write windows open source SIP client. And have problem.
PJSIP API give me NAT detected as Symmetric.
As result when I call from first PC to second - all right, when
from second to first - (ICE negotiation failed and no sound).
I have NAT on Gentoo Linux machine.
All other software (NetDetect, client.exe) detect NAT type as
"Port Restricted Nat, preserve ports, no hairpin".
Is something wrong in pjsip STUN algorithm?
Second small question. Why, when ICE negotiation failed, PJSIP do
not send voice over SIP media proxy server and as result - no
sound?
