example/proxysip - rtpproxy

Hi,

This is really a nice project and good to see how powerfull go is for voip solutions as well ;-)
One question remains however on the proxy part, the primary focus is now on the SIP handling, what would be needed to intregrate and RTP proxy as well?

Thanks. Yes I think the same.
I not sure do you think integrating some already existing rtpproxy project or writing lib for handling?
It will need some SDP handling in both cases I think.

There is rtpproxy, which is available. but it is not written in Go unfortunately.
Indeed the SDP handling is mandatory, since it needs to sit in between a sip client and a sip server, both the client and the server should not know about they are communicating to a proxy

I guess you mean something like kamailio use which probably has some comunication protocol between. It is something for future + features to run SBC.
SDP parsing already has some libs in GO, but maybe we see own lib here for SDP as well.
