Custom tone detection (job?)

Postby tfbu » Mon May 25, 2015 6:06 am

I need to build an alarmreceiver style app that works as follows:

Play specific tone for specific duration
listen for blocks of another tone in dial pulse fashion, three tones == 3, five tones == 5, etc
Play another specific tone for specific duration as ACK

Can Asterisk AGI be made to play and decode custom tones?
Can Asterisk count tone pulses?

Looking to hire someone to do this.

Hey Gentleman,

do the tones received need to be decoded - ie do you need to know which frequency is being played, or just the fact that you have sound then silence ? if the latter, you may use BackGroundDetect.
