It could be a port issue, but then you would have one way, or no audio, not just no DTMF. I would suspect that it is an incompatible DTMF Method setting, on the set(s) you are using. Have you tried more than one set, or type of set? 3CX App? Have you checked to see what is supported by your provider?

If you call other numbers, like your mobile, or home phone, are you able to hear the DTMF tones sent from the PBX end?

yeah tried dialing to my mobile, i can hear the keypress dial tones from my mobile.

Ill have to check the DTMF Method setting with regards to sets.

Are you finding that you are unable to use any external service that requires DTMF, or is it just some? I'm assuming that access to 3CX voicemail options (internal DTMF services) is working correctly.
