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

I think its only capability with FXS is to fluctuate the voltage to support distinctive rings. -- Bird's The Word Technologies, Inc. http://www.btwtech.com/

Is this correct?Anything that analog is probably the job of the digital-to-analog chip used. Not of the digital stream sent by Zaptel.> > Despite looking through the zaptel source code, I couldn't find anywhere > that screamed "I'm the volume your phones ring at".

I'll just note that component used in the Astribank is quite similar to the one used by Digium in the TDM400P and TDM2400P . Grep for proslic.

I can't imagine significant difference in ring volume due to higher ring voltage on any modern phone. These aren't old carbon-granule phones with mechanical bell ringers, are they? -A.
