[Asterisk-Users] Zap channels ringing too loudly

[Nick Burch]

Hi All

I've got an asterisk system, using a couple of Xorcom Astribanks to 
provide FXS ports. (I'm using the zaptel 1.2 branch, if that matters)

I've noticed that the ringing volume is a lot louder than on our old phone 
system, and people are starting to complain it's too loud. (This is the 
noise the phone makes when it rings, not the noise in your handset when 
you ring someone else)


Having had a look through the code, I think that Asterisk passes the 
responsibility for ringing the phones to Zaptel, which drives the 
astribank to make them ring. Is this correct?

Despite looking through the zaptel source code, I couldn't find anywhere 
that screamed "I'm the volume your phones ring at". Just a lot of scary 
numbers in zonedata.c, and cryptic comments in tone_zone.h


Could someone suggest how I'd go about making the zap ring volume quieter?

Thanks
Nick
