Answering machine detection cpu load

Hi to all,

anyone know how much is AMD cpu intensive?

In a machine that generally can handle 100 simultaneous calls without AMD, how much percentage of load AMD will it take? (asterisk 1.8.32)

What else is being done (in particular, are calls internally or externally bridged, and are you using inband DTMF)? For what proportion of the call seconds is AMD actually running?

Without having looked closely at the code, I would think it was a lot less CPU intensive than inband DTMF detection and would also have a lot lower duty cycle.

My suspicion is that most of the cost will be in any transcoding that has to be performed, and that will be needed for inband DTMF, as well.

The best way of answering performance questions is to actually try the real system in your environment.
