RTC behind NAT non-UPNP
Saulo Machado posted at Monday, January 28, 2008 12:48 PM
Hello all, I'm developing a SIP softphone using RTC API 1.3. When I'm behind NAT non-UPNP, I can't register to SIP Server. In RTC 1.5 for Windows CE, there seems to be a solution for this via the interface IProfilePortManagement, but in RTC 1.3 for WindowsXP, there isn't a simple straight solution such as that. How can I register the IRTCProfile in SIP Server (Asterisk, OpenSER, etc) when using NAT non-UPNP ? Or ... how can I use STUN for registering profiles under RTC 1.3? Thanks for anyone who can help!!!
