Hi Răzvan,
Any further directions on this please?
I did get it to the point that it will fork the media for one or two calls but thereafter it requires the opensips to be restarted before it works again. Is this a bug in the module or is it because of the way I'm using it?
Thank you.
Eugene Christensen.

Thanks Răzvan.
What I'm exploring is the ability to fork all the media of a call to another SIP entity. When I do this, it could be at any time during the call.
I did look into SIPREC and played with that a bit too but since I wish to be able to do this at any time during a call, SIPREC doesn't seem like the best solution since it appears to want to get negotiated at the beginning of a call.
Ideally, I would like to do the following:
Identify a call that I would like to be able to receive both the caller's and calle's media. Once identified, send the appropriate commands to fork the media (A/V/T) from both endpoints in the point to point call to another SIP entity. I do not wish to have the receiving device send any media back in return.
If I am understanding things correctly, I should be able to create a dialog and engage RTPProxy (or RTPEngine) in the original call to anchor the media so that if/when I wish to fork the media, the media and dialog are already established where needed.
I am able to get the receiving device called now but I do not see media being sent to it.
Does this help explain my intentions and needs?
Thanks,
Eugene Christensen.

Hi, Eugene!
The idea is simple: a socket/listener represents an
interface+protocol+port OpenSIPS listens on and is able to use.
In your initial tests, you were trying to send the call to a UDP endpoint, but you were only defining a TCP listener - hence the failure.
Please let us know *what* you are trying to achieve so we can guide you to the right documentation.
Best regards,

The unaltered address is a public reachable address where I have a SIP device listening for an incoming SIP call, presumably from the OpenSIPS server when I run the media_fork_to_uri command.
