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.
