[OpenSIPS-Users] Media Exchange API media_fork_to_uri

[Eugene Christensen]

Hi Răzvan. 

Thank you for looking at this with me.

Attached is my opensips.cfg file.

In addition to starting OpenSIPS, the only other thing I am doing is starting RTPProxy using the following command.  If there is more that I should be doing to configure listeners, I am unaware.

	rtpproxy -u admin -s udp:127.0.0.1 12345 -l 172.31.6.99 -A 52.24.166.239


I don't expect that rtpproxy and the configured addresses for it are having any bearing on this but I could be wrong.  I'll explain the addresses here and in the config file.
172.31.6.99 and 52.24.166.239 are the private and public addresses on the server running OpenSIPS and the rtpproxy (both on the same machine).  

The 123.123.123.123 address in the config file in the media_fork_to_uri command has been altered for this thread.  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.

Does this answer the question about the listeners or am I missing something that I need to do for listeners (or other)?

Please advise.

Thank you.

Eugene Christensen.

Hi, Eugene!

Could you give us a bit more information about the listeners (sockets) you are using?
