RE: [Asterisk-Users] Buzzing on TDM400P FXS?
Haven't seen this, but I do hear a loud click about 5 seconds into any call involving a TDM400P port. Seems like something might not be quite right with the Zap driver. -brian -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Scott Laird Sent: Monday, April 05, 2004 1:42 PM To: [EMAIL PROTECTED] Subject: [Asterisk-Users] Buzzing on TDM400P FXS?

Re: [Asterisk-Users] Buzzing on TDM400P FXS?
I had slightly different problems - but the resolutions might help you: I had a problem with an intermittent loud buzzing on my X100P (heard when accessing PSTN from my SIP and Zap clients). The problem went away when I physically moved the card down a PCI slot (further away from my TDM400P and my power supply). I also had an additional problem with jittery/choppy sound when receiving calls from PSTN on SIP devices. This was due to my X100P sharing interrupts with other devices (e.g. NIC).

Re: [Asterisk-Users] Buzzing on TDM400P FXS?
Had a similar problem What kind of phone are you using on that line? My case, the line was sharing a Palm modem on it. Electrical noise from the power strip was causing the problem. Also when My cell phone was too close to the phone, same problem Also found the VMWI logic was not working well with the PALM modem and took the mailbox off that line --- Scott Laird [EMAIL PROTECTED] wrote: I have an intermittent problem with the one FXS line that I have.

Unfortunately, I only have one FXS port at home, and that makes it hard to debug audio problems. Fortunately, UPS dropped a Cisco 7940G off this afternoon, so I'll have a second high-quality audio device to play with, and that should make it a lot easier to fix.

Electrical noise from the power strip was causing the problem. I'm having a similar problem. The difference was that if I reloaded the zaptel drivers the buzzing went away. It seems like the card got into a strange state. It might be the system though, because I have another box that hasn't experienced this problem. The x101p's don't have very good filtering. When I had a gig-E card in one box is was causing a lot of faint bleeping or buzzing. Taking out the card helped a lot, but I still get some odd sounds. I wonder if these can be filtered out using a software bandpass filter since the remote site doesn't hear anything. ...Jeff ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
