No DTMF on new install

just installed a new freepbx appliance with the latest Freepbx and a sangoma gateway 50 with 5 analog lines in.

problem is, when I dial out I get no DTMF. Can’t interact with any IVR’s etc.

if I make a call from one internal extension to another, then start recordeing (*1) and dial any of the keypads I hear the tones on the earpiece of the phone I’m on but not on the receiving end. Also the recording does not record any tones at all.

the extensions are set for rfc2833.

I’ve never had this issue before, any ideas?

Issue fixed. Because the sangoma gateway is dumping to analog lines I needed to add “dtmfmode=inband” to the trunk peer and user settings.
