Hi, I'm setup the Asterisk 1.4.33 and try test it with the PortSIP SDK(<a href="http://www.portsip.com">www.portsip.com</a>), but seems the video does not works.<div>When I make the call from PortSIP SDK Demo to GrandStream GXV3140, it's working fine if no video codec selected.</div>
<div><br></div><div>If make call with H.264 codec, the PortSIP got "503 service unavailable" response from Asterisk, why?</div><div><br></div><div>Thanks</div><div><br></div>
