That is very interesting stuff!!! I've experienced, and still continue to experience, the "line noise" issue, as well as the beeping issue.. The beeping issue took one of the people I was talking to by surprise, he thought the conversation was being recorded..
I have 3 X101P cards for my 3 inbound POTs lines, and I have 3 SPA-2000's connected to my local lan, along with 3 Grandstream Budgettone 100 IP phones, and a remote SPA-2000 at a friends house in a different state. The whole system is running on an older dual processor PII 450Mhz machine with SCSI drives.. 512Mb ram.The system runs RH9 with asterisk version Asterisk CVS-HEAD-03/26/05-17:05:44 built by [EMAIL PROTECTED] on a i686 running Linux Please keep me up-to-date on if this permanetly solves your problem(s), as I can certainly throw more hardware at this if needed!!!

Regarding the static that floods the line and makes continuing a conversation impossible. This was happening on my SIPura-841, but Damian on the list was experience this same problem with POTS phones as well through his TDM400. Below is an excerpt of what I recently sent to Damian as we've been trying to figure this out. Well here’s the deal with my box. I had a Celeron 400 w/ 128mb of ram and an UATA66 HD. I finally got fed up with the static on the phone(because it would basically cut the conversation off), so I went out and bought a brand new system. Sempron 3000+, 512MB pc3200, 160GB UATA100…..fresh install of asterisk and zaptel and RH9. I have two X100P FXO cards in my box. Prior to upgrading I ran zttest and observed the results….they were something like an average of 99.96XX…which is below what digium is recommending. So I went and upgraded. I tested the phone for a little over 20 minutes and it never cut out or went static one single time, however, it was making a beeping type sound in the background. It was sporadic and varied in volume. I have no idea what is causing it, but at the moment I’m quite relieved that it’s no longer(crossing my fingers) cutting my phone calls off. I ran a zttest on the new box and the outcome was much better, 99.987 for most of them, an occasional 100% and sometimes it would dip down an go to 2%, 40%, 70%,ect. But the test ended and the average was above 99.98. This whole damn thing is quite frustrating, more so for you I can imagine. I hope we’re closer to a solution now. Have you seen anyone else on the list that has found a cure or workaround? BTW, I was running samba and I stopped the service, but the static continued. (We thought Samba might be part of the problem as my TCPDUMP showed netbios activity at the exact time the line went south...no dice though) Update further...The first conversation on the phone had the beeping as described above, it occurred throughout the conversation. All of the subsequent calls made (about 5, all less than 5 minutes) have been crystal clear and I couldn't tell the difference from that or my POTS phone connected to the local loop. I do have a concern though, if the TDM400 is so seemingly problematic, what else could one use to connect multiple analog phones to the box???
