Hi Alex,

No, there is no dedicated var. But "looking" into SDP is the correct 
approach. And you will see there ONLY what the device sent you (it may 
be a private IP, if the device is natted). But the real src ip where the 
RTP is coming from may be "visible" only to a rtp relay, not to OpenSIPS 
(it is not reflected in the SIP/SDP part).
