Failed to Create Session

[Stanislav Karavaev]

Hello, I going to create a IVR in couple with the GSR plugin, but I got a problem

Asterisk saying that happened error:

I guess, I've configured connection with MRCP server incorrect, but I'm not seeing where exactly

8060 and 8062 ports are opened:

I launching MRCP server via CLI and I don't see any received SIP event there

What can be wrong?

Hello Stanislav,

You may need to enable debug output in mrcp.conf and logger.conf, located in the Asterisk config directory, to identify the problem.

BTW, also check for any warnings on loading of modules res_speech_unimrcp and app_unimrcp.
