the scenario is similar to this: [1]kamailio+rtpproxy (private IP) -> Router public IP > [2]kamailio+rtpproxy (PRIVATE IP listening on public IP)
when the caller is registered on [1] and callee on [2], rtpproxy [1] is correctly engaged but rtpproxy [2] shows an error : "incorrect port 0 on reply" and there is no video/audio if caller and callee ( in 3G/4G mobile network) the call is handled correctly both audio and video I'm running out of ideas, I hope someone can help me... thanks 2016-06-27 17:37 GMT+02:00 Filippo Graziola <filippo.grazi...@gmail.com>: > Sorry my thoughts weren't correct.
