Hi,

I am observing a STUN related issue with PJSIP for last few days. Many times, the PJSIP stack does not get initialized as it does get a response from configured STUN server. I am using PJSIP through the wrapper written for Sipekphone project.

On checking the logs, I found that it is destroying itself after throwing following error:-

Error contacting STUN server: Received no response from STUN server (PJLIB_UTIL_ESTUNNOTRESPOND) [status=320010]

Lately, there has been slightly more network activity in my setup which may be resulting in more delay & packet loss on WiFi router. Can it result in failure of this NAT check?

Log file indicates that timeout occurred within 5 seconds of transmit of first Stun request message. Is there any setting which can increase this timeout value so that NAT check can work in more congested and lossy network?

Please help. I am attaching the Log file also for your reference.

Regards
Girish
