Dear All, We are currently investigating the possibility to forego STUN checks on the client and to avoid using RTP relays. By not using these we simplify the client call code, reduce the number of components to maintain and avoid the relay latency. Ideally, the client does not send any transport information as part of the call setup. Instead, we'd like call to be established without FreeSwitch knowing the IP address or media ports for the client. Once a call is answered, FreeSwitch tells the client what IP and port it should use for the media stream. The client sends the RTP stream to the specified IP address and UDP port on FreeSwitch. FreeSwitch uses the incoming stream to determine the IP address and UDP port of the client and sends its RTP stream there. 1) Is this possible? 2) What do I have to do to do this. -- Kees Jan http://java-monitor.com/ kjkoster@kjkoster.org +31651838192 The secret of success lies in the stability of the goal. -- Benjamin Disraeli
