Hello, I resolved my echo issue using grandstream/estara etc etc sip phones and wcfxo interfaces from digium. I swapped out my via kt400 based msi kt4vl motherboard for an asus p4pe? i845? based motherboard and the echo has completly gone away along with aggressive suppressor option in the makefile. I hope this helps others. Brian J. Schrock Anistone Technologies, LLC 6926 Avery Rd. Dublin, OH 43017 Phone: 614-798-9106

I had terrible echo and noise on an ASUS A7V133 with a Promise Raid controller. I tried an old HP Vectra and it all went away. Then I needed some more PCI slots so I changed to an MSI K7T266 expecting all kinds of noise, but it is as clear as a bell. This machine now has the X100P + T100P + Bewan PCI ADSL card. -- Dave Cotton <dcotton@linuxautrement.com>

Agressive Suppressor is active in the makefile. ----- Original Message ----- From: "Andrew Kohlsmith" <akohlsmith-asterisk@benshaw.com> To: <asterisk-users@lists.digium.com> Sent: Wednesday, October 15, 2003 8:07 AM Subject: Re: [Asterisk-Users] WCFXO echo rexolved for me> > I resolved my echo issue using grandstream/estara etc etc sip phones and > > wcfxo interfaces from digium.

Hi, Could you give me some more details on the motherboard? Exactly which model of i845 is it (we are using an i845GL, and it has terrible echo)?

I'd guess this qualifies as a bug report -- is there a reason for X100P being so dependent on the motherboard used? Some of us don't have the option of swapping out the hardware. --J. -------------- next part -------------- A non-text attachment was scrubbed...

Brian, Ok, I'll take a closer look at my BIOS later tonight and talk to another programmer to see what options might be the best to try. Thanks for being willing to do this, if you actually find a setting that makes a difference, might help a lot of people. Since it's just a lab machine, at least you're not messing up anything important. I do know that one of the reasons why we hate to assemble computers from components at our company (i.e. buying motherboards, processors, video, etc. boards all separately and plugging them in together) is that half the time there's some weird timing issue that causes all kinds of quirkiness. I had a friend who would actually get out an oscilloscope and check to make sure all the timing looked right, and you'd be surprised how many cheap pci cards don't quite work right with certain motherboards, and vice versa. And there's really no way to know about all these conflicts unless you build lots of computers and/or use a scope. So now we just buy Dells or HPs or something, not the highest-end equipment, but much less quirkiness since they have engineers checking out the timing of all the boards, making sure there's no weird conflicts, etc. With Asterisk, it seems a huge amount of the problems people encounter is getting all this equipment from different manufacturers to work together. I guess since there's really never been such an open telephony product quite like Asterisk before, it's like the wild-west for us. -dana>I'll give it a shot, but that stuff is a little out of the realm of my >knowledge.
