asterisk users - Dec 2022 - Receive DTMF and record audio at the same time

Hi Everyone,

I am trying to find a way to build an AGI script or dialplan that can handle a
“please just say OR enter the post code (zip code) you want” voice IVR. I
already have a speech to text solution working with the AGI Record command and
this works. Of course a standard DTMF menu is easily done, but I don’t know how
to do both at the same time. I need a non-blocking way to also receive the DTMF
digits while listening for a voice at the same time. Or I suppose a non-blocking
way to record audio might work, and keep the DTMF Read() as blocking?

My big limitation right now is that we are still on Asterisk 11. I am planning a
move to Asterisk 18 but even this doesn’t seem like it would support StoreDTMF
which would have probably been a solution. I would appreciate any ideas on how
to do this.

Thanks.

StoreDTMF is part of Asterisk 18[1].
