; When cidstart=dtmf, the energy level on the line used to trigger dtmf cid
|

; acquisition. This number is compared to the average over a packet of audio
|
||||
; of the absolute values of 16 bit signed linear samples. The default is set
|
||||
; to 256. The choice of 256 is arbitrary. The value you should select should
|
||||
; be high enough to prevent false detections while low enough to insure that
|
||||
; no dtmf spills are missed.
