That's not really a dtmf mic. It's a mic with 15 switch closures and a 10 a pin connector to plug into a CDM mobile so that the mobile knows which dtmf tone to generate.

It's a standard Moto 8 wire pinout for Maxtrac, M1225, etc for pins 2-9. Pins 1 and 10 were added for the keypad functions in the CDM series. We found jacks, plugs, and crimping tool at Graybar (if I recall correctly) so we could fab extension cables.
The obscure 10 pin jack has been
discussed in the past here.
