<p>Ok understood. The signaling wont be a problem, but not the same with rtp as it uses randomly ports. The idea is to have an intermediary who could delivers both ports and ping them to both sides to keep nating open on routers, this is what i do with rtp proxy within opensips.</p>
<p>But in this case no OpenSIPS. The router are Comtrend and linksys.</p>
<p>Are you sure that works for you with the same environment as mine? Its just that im trying to understand it technically (sdp headers + sip headers) and i do not understand how the rtp will reach both phones on different nat sides</p>
<p>The routers does not have ALG.</p>
