I am wondering if anyone of guys have come up with a solution using DTMF and voice reply to a certain set of keystrokes. What I mean is - I need to play a recording e.g that the alarm is on when the customer calls into their home and punches a certain key stroke sequence. I am thinking of using a computer but that is a overkill for a simple solution. AMX suggested that I use roland midi unit that records voice and plays when it receives a certain note. I am trying to see if there are other solutions. Thank you for your inputs.
