Cant get DTMF tones to work?

[seanbts]

Hi All,

Using Yealink T28's with 3CXmini and Blueface in Ireland as our Voip Provider, I cant get dtmf tones to work, the handsets are set to RFC2833 and so is our account with the provider. If i connect a yealink directly to our provider it works but not through 3cx, any one any ideas?

Here's the log:

14:59:16.953 [MS211000] C:24.1: 192.168.1.40:11780 is delivering DTMF using RTP payload (RFC2833). In-Band DTMF tone detection is disabled for this call segment.

Which end is not responding, places/numbers you are calling from a 3CX extension, or, incoming calls to your voicemail or automated attendant? If it is on outgoing calls...I would try changing the DTMF settings in the set, there are usually a number of different combinations that can be set. I assume that your codec is G711u/a ?
