Hi,

I am facing an issue while setting up Azure SR using the res-speech-unimrcp flow.

I do see 2 "Failed" messages in the asterisk logs. But I am unable to understand what I am missing here.

I've followed the docs as per this link: https://www.unimrcp.org/manuals/pdf/AsteriskBingUsageManual.pdf

If I run the command run bsr1, it does give the expected output as per this doc.

If someone can redirect me to what step I am missing, that would be really great!

extensions.conf

Hi Jatin,

The above statement would indicate no intersection (or no codec translation path) is available between codecs used in the incoming SIP leg and the ones configured to be used in the MRCP leg.

Hey Arsen,

Sorry for the delay in reply here.

In an attempt to get it working, I had changed a lot of config files without understanding what they did.

I re-deployed all of it (asterisk, unimrcp, AzureSR and Azure SS plugins) from scratch as per the documentation and it started working as expected.
It was clearly some config issue, but I am not really sure which change broke it.
