[Freeswitch-users] Moving RTP relay to another FS BOX? (FS+MediaProxy?)

[Fabio Pietrosanti (naif)]

I find no documentation on OpenSIPS to Media-Dispatcher communication
protocol.

All i just see is from logical point of view is that:
- OpenSIPS talk to MediaDispatcher trough a UnixSocket
- then Media-Dispatcher send a request to Media-Relay via TLS
- Media-Relay answer to Media Dispatcher the allocated IP/UDP ports for
RTP relay
- Media Dispatcher provide the IP/UDP port allocated to OpenSIPS
- OpenSIPS mangle SDP attribute to tell the SIP clients where to send RTP

Now, i am not finding details on OpenSIPS<->MediaDispatcher protocol,
but maybe it's something incredibly easy so that few lines of python
could make it working.

Any idea?
