Hi, to solve the problem of being behind a NAT there are two "schemes" known to me:
First one does two igroups of STUN requests. First request to retrieve informations about the kind of NAT and being kept informed about changes of the dynamic public IP and the second request is done to determine the portmapping for SDP/RTP. Second one does only use STUN to get informations about the kind of NAT being used. In the SDP there are used local ip-addresses in combination with "rport". Resolving of the public IP-address and port becomes therefore a job of the SIP-/VoIP-provider. Question is: Is it reliable and working to use "rport" and to rely on the "STUNning" capabilities of the providers SIP-server? Any comments are welcome.
