Saving UniMRCP Channel-Identifier to FreeSWITCH CDR

[Sean DiSanti]

Is there a way to access the channel-identifier value from FreeSWITCH, so that we can add it to our calldata record? I'm able to see it in the console, but have not had much luck in trying to access it programatically.

Hi Sean,

I do not think such an option is available, but it should not be hard to extended mod_unimrcp.c in FS to pass the channel-identifier along with results. The function recog_channel_set_result_headers() appears to me the right place to look at.

With your advice we've successfully captured the channel identifier to add to our calldata. Now we are looking to see if it's possible to pass a piece of information like the uuid into unimrcp and have it make it into the log, so that we can do the same look up from either direction.

The same channel-identifier that you added to your call data in FS is available in the server logs too.

BTW, the MRCP header field Logging-Tag can possibly serve the purpose to pass additional information from the client to the server. However, this header field is not processed by UniMRCP server as of now.
