Can you send the complete trace from the SIP window to support at ag-projects.com

Everything works from the web interface (Flash-based) but I found it almost impossible to configure a client to work with it from behind a NAT. The provider offers stun.clicknet.ro (18.104.22.168) as a STUN server.

Clicking "Accept" does indeed send some messages to the server (as seen in the Logs), but the PSTN number keeps inking in the mobile phone.

The audio state changes to IDLE after I accept the call in Blink and nothing happens for several seconds (meanwhile the call keeps ringing on the initiator's side). I have also looked in "Blink Logs > SIP" with "Everything" selected. There is no mention of "STUN", "stun", "22.214.171.124" or "stun.clicknet.ro", making me believe that STUN isn't really active. The Log snippet below shows that NAT was indeed detected.
> Also, on a side note, Blink must be approved on each start, if the Mac OS X firewall is turned on. This is a bit weird, considering that it is added the first time to the list of applications which can accept incoming connections. Everything above was found both with the firewall turned on and with it turned off.
