[Asterisk-biz] IP Displays for public telephony booths

[ht at phonitel.com]

Hello,

We do have a call meter solution. The way it works is that it is triggered by 12
khz, or 16 khz frequencies.

So this only works if you have a frequency generator based on a rate table.

The question is interesting of how to make those work with Asterisk:

1-) Can asterisk generate 12 khz signals on its interfaces?

2-) Can it send such frequencies signal on the ;

3-) Any other concept ?
