Hi Flavio,

Can you please give me the output of the command "rtpproxy -v"?

The word "session" specifies RTPProxy to search for the codec list in the initial Update command (when OpenSIPS calls rtpproxy_offer), so there is nothing wrong with it.

This is how RTPProxy works when it receives a Play command:
Assuming your initial codec list is "3,8,101", your command is interpreted like this: it checks in the '/var/rtpproxy/prompts/' folder for the 'dmcaller.3' file (which should be a GSM encoded file). If found, it starts to play it to the uac/uas. Otherwise it checks further for the 'dmcaller.8' file, and so on until it finds a suitable media file. If it doesn't, it should log an error. I guess your problem is that RTPProxy is unable to find a suitable file to open.

Regards,
Razvan

Hi,

Is there anyone with experience using rtpproxy_stream2uac command. I'm trying to use with OpenSIPS 1.6.4 with rtpproxy-1.2.1. I'm getting the following error:

ERROR:nathelper:rtpproxy_stream: required functionality is not supported by the version of the RTPproxy running on the selected node. Please upgrade the RTPproxy and try again.

1. I tried to upgrade the RTPPROXY with the on in GIT, but it crashes as soon as I start OpenSIPS.

2. I tried to disabe the check in the rtpproxy_stream2uac, I don't get the error but still don't work. In this case:

OpenSIPS is sending to the RTPPROXY

DBUG:handle_command: received command "23907_6 P10 [email protected] <mailto:[email protected]> /var/rtpproxy/prompts/dmcaller session 5cc2dfbec1d32747o2;1 as1dc4b372;1"

The RTPPROXY is expecting according to the RTPPROXY protocol

P[args] callid play_name codecs from_tag to_tag

The mismatch seems to be in the word "session" in this place rtpproxy is expecting the codecs.

I tried everything I could.
