DTMF with ASR not working

I have integrated ASR on my Asterisk and trying to deduct Customer Voice after hold and than Transfer Call to Available Agent which is logged in to Asterisk Dialer.

In this scenario, all works fine without passing DTMF Input but when initiating call with DTMF input (using MRCP to connect Asterisk) the ASR is not accepting or working.

Also, DTMF is working without ASR, it is interpreted and accepted at Customer End (IVR)

but together with ASR, the DTMF is not interpreted at other end (Customer End IVR)


You might try changing DTMF mode to inband audio.
