What is the difference between inband and out-of-band DTMF?
Can you please clarify the distinction between inband and out-of-band DTMF? In simple terms, how do these two methods of transmitting dual-tone multi-frequency signals differ from each other? I'm interested in understanding the key differences and when one might be preferred over the other in terms of performance, efficiency, or other factors.
