outbound dtmf, button press not passing to called party menu system

[wpanagotopulos]

Anyone having issues with outbound dtmf ?

we suddenly are unable to navigate any outbound calls into menus with any button presses. eg. 1 for sale, 2 for support, etc. pressing any key results in nothing heard on the other end.

Thought it was an issue with our sip provider, but have tried two more now and no success.
So I think it is in the 3cx box itself after an update.
We are on v18 update 9 build 31... so I'm at a loss.

The easiest way to see if the PBX is receiving and sending the DTMF tones is via a wireshark capture on the PBX.

Place a call with a capture running and see in the capture if you see the DTMF events

Have you looked at the 3CX Activity log (Verbose) to see what DTMF Method your devices are sending? Are all phones/devices the same make/model?
