Good quality DTMF converter.

I bought a couple of these boards to add Touch-Tone capability to a 1978 OKI Electric AC125A Crossbar PBX. They work great. Documentation can be found online with a little searching.

Pros
  • DTMF from phone or hand held radio work very good
Cons
  • The 8CH DTMF Relay Phone Voice Signal Decoder Module comes with a complex wiring system that may seem daunting for inexperienced professionals
