Re: STUN Server vs. NAT Configuration with Kamailio + RTPengine Setup

Hello,

usually, a STUN server is not needed if your clients behave appropriate. Microsip should be fine, if you don't configured something strange.

Regarding test cfg, the default Kamailio configuration should usually work with the appropriate #!defines set.

Cheers,

Henning
