I have been working on getting 2 GS BudgeTone 100 to work both behind NATs. Am I suposed to be able to do it using only a STUN server?
Right now i need to use the STUN server and also open ports on the NATs for the audio to go through. When the ports are closed and I use the STUN, the phone status says Restricted Cone and the audio is blocked. If i open the RTP port the status says full cone and it works. But shouldn t it be working only by using the STUN server and leaving the ports closed?
