#87244 - Caller ID and DTMF are Different Responding to: ???'s previous message |
Caller ID is normally bell202 tones as 1200baud fsk (if my memory serves me correctly) and DTMF is totally different.
If the problem is that you cannot receive DTMF tones from another caller, then I would suggest you check the signal levels with an oscilloscope. |
