[Asterisk-Users] BUSY_MIN, BUSY_MAX AND BUSY_THRESHOLD

[Gelson Dias Santos]

I´m trying to get busydetect working with an analog PBX. I have an 
extension connected to a X100P. PBX generates a 230ms tone, followed by 
70ms silence, another 230ms tone, 70ms silence and keeps repeating the 
pattern.
I´m not sure if I understand how BUSY MAX, MIN and THRESHOLD  in dsp.c 
works, because I have the default values from 0.9.0 and it does not 
detect the busy signal:

#define BUSY_PERCENT            10
#define BUSY_THRESHOLD          100
#define BUSY_MIN                75
#define BUSY_MAX                1100

Can someone with more experience intunnig these parameters suggest me 
the right values I should use?

Thanks
