Get fax transfer mode in dialplan

I’m using asterisk 16 and spandsp to receive faxes.
Is there any way that I can get the information if a fax was received in G.711 or T.38 within the dialplan?
Maybe a channel variable that I’m missing?

Many Thanks!

The FAXOPT dialplan function[1] has all the information available, looking at it I don’t see anything that stands out but you could experiment and see.


Thanks for your reply.
Unfortunately none of the FAXOPT vars give an indication if the fax was received in T38 or G711.

On the CLI - if you issue “FAX SHOW STATS” it will give you the stats per transaction mode. I want to write the info into the DB on a per call basis for analytics.
