Assume two SIP endpoints, no NAT involved. > That will only happen when the call is natively bridged: Non-native bridge: Packets can get translated or Asterisk has an interest in the packet for things like DTMF or call recording. Native bridge doing packet-to-packet (Local bridging): Packets come in on one channel and go out the other channel with nothing else done to them. Native bridge doing direct media (Remote bridging): Packets go directly between endpoints so Asterisk never sees them. Richard
