Help.
When an incoming isdn call is answered I need to send dtmf tones (digits)to the remote machine to operate various options this does not work, I called in from my mobile phone and tried to send tones (dialled digits from the keypad on the ipecs phone) and it doesn't send any.
Is this feature available?
Where would I find the setup in programming to turn it on?
