There are two times that I have encountered this issue. Once was a bad TDM400P motherboard. I figured it must be the FXO daughter board but after replacing it, the same behavior continued. Anyways, that particular port was total static all the time, I confirmed by moving all the daughter cards and actual phone lines but the problem remained on Zap/1.
The second time I saw this behavior was when a splitter was placed before the PBX for outbound faxing. Asterisk would hear noise on the line and answer the call. It took me a few minutes to put the two together, someone sends a fax and all the extensions start ringing with fax tone ;-) Thanks, Steve Totaro http://www.asteriskhelpdesk.com KB3OPB > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:asterisk-dev- > [EMAIL PROTECTED] On Behalf Of Marius Stankevicius > Sent: Wednesday, March 28, 2007 2:56 AM > To: 'Asterisk Developers Mailing List' > Subject: RE: [asterisk-dev] Problem with phantom rings.... > > > > No nise in the line during calls, but there are random spikes of noize > when > phone is on-hook.
