Dial numbers with the call established (IVR)

Good morning, I have a problem, when I call a number that has an ivr with options, it does not take any of the digits I dial to choose the internal. What am I missing to configure?

Does this happen with every IVR that you dial into ? Or only some IVRs ?

What is your current “DTMF Mode” inside Connectivity → Trunks → YOUR_TRUNK → pjsip Settings → Advanced ? Should be one of:

The DTMF signaling mode used by this trunk, usually RFC for most trunks
    Auto [Asterisk 13] - DTMF is sent as RFC 4733 if the other side supports it or as INBAND if not.
    rfc4733 - DTMF is sent out of band of the main audio stream.This supercedes the older RFC-2833 used within the older chan_sip.
    inband - DTMF is sent as part of audio stream.
    info - DTMF is sent as SIP INFO packets.

You might consider trying different options and seeing what works for you.
