Hi there, But there is a problem if one client uses STUN to detect the outbound IP of the NAT-Box and changes the IP-Address of his SDP body to the outbound IP-address of the NAT-Box. The original local IP-Address ist lost. This value must be recovered by SER - otherwise the RTP-stream of this local connection is relayed over the public internet. I managed

By using STUN and the public IP address, the call does not goes into the public internet - only to the NAT-box and back into the LAN. btw: this works only if the NAT box supports "hairpin of media". If not, you also have to use an RTP proxy.
