Hi, I'll just answer this in general rather than specificly to your problem. There are two things to solve when it comes to NAT. First is the problem with getting the signaling (i.e. SIP) going through NAT between peers, and the second is with getting the media (i.e. RTP/RTCP) going through NAT. ICE only solves the second part, i.e. media. Before it gets to ICE negotiation, you first need to make sure that SIP can get through from caller to callee. One way to do it is to have both caller and callee register to SIP proxy, and configure the proxy to record route so that all SIP messages between the clients always go through the proxy. *Only after* you solve the SIP signaling issue you can get to solve the next issue, i.e. the media.
