[OpenSIPS-Users] OpenSips as simple frontend to Asterisk to deal with NAT

[Nick Cameo]

You will need RTPProxy to manage the media and proxy that over to
asterisk in order not to get `retransmission timeouts`. RTP Proxy is
very versatile, perfect for far-end NAT setups. We use it in our
deployment. You can hit me up  if you require a working config.

OpenSIPS does not manage media (ie, RTP Stream)

Kind Regards,

Nick.
