Connecting AirLink FXT Series To legacy DTMF Phone


#1

Hi there,

I would like to know if Is there anyway to connect a dtmf phone to the airlink fxt, i’ve tried to use the mic input to decode dtmf signals, but in that case there’s no signal source.

What, exactly, do you mean by that?

Do you mean a phone designed for connection to the PSTN? If so, the answer is, “No”.

Ok , So I’ll use the head set for the mic and speakers and use GPIO or RS232 for keyboard. Just trying to save some money… Any recommendations for the keyboard? Tks awneil!
