QUESTION Incoming call to extension with Confirm Calls - DMTF not working

[Rrrr]

Mobile user cannot confirm the call with DTMF when calls go via trunk A (anveo, dtmfmode=rfc2833).
Mobile user can confirm the call with DTMF when calls go via trunk B (difference provider, dtmfmode=info).

I would like to know what to do to have DMTF working over trunk A.

My system ( Asterisk 11.18.0 Incredible GUI 12.0.30 ).
The calls are incoming (from DID or from another extension) directly to an extension, which has confirm calls enabled and forwards calls to a SIP device and to two mobile phones:

303
003xxxxxxxxxxx#
001xxxxxxxxxxx#

I have tried to vary the dmtfmode setting in the outgoing trunk A (inband, auto), but no success.
How can I get DTMF working on trunk A?

A DID is forwarding calls using SIP URI to my system ( Asterisk 11.18.0 Incredible GUI 12.0.30 ).

Can it be related to a system setting on the inbound SIP URI?

I know it might seem silly, but have you tried holding down the key for a longer time? I have had trouble in the past where in order to get the pbx to recognize the tone, I had to press and hold the key. Sometimes I have the tendency to just quickly tap the key which a cell will recognize but dtmf in audio will not because it is to short. I usually use rfc2823, btw.

Trunk A does not allow me DTMF and I would like to know what to do about it.

On the trunk group that does not work, set DTMF=inband and see if that works. Also, if you are running G.729 on the trunk in question, DTMF=inband won't work either. Depending on the provider, rfc2833 is not always reliable.

Try looking in the /etc/asterisk directory
There are various logger* files existing
Or from console

root@raspberrypi3:~ $ ls -al /etc/asterisk/logger*
