I had a similar issue before, but it was with a T100P connected to an Adtran TA750. The phones we were using were Polycom SIP IP 500 phones. What we did (and anyone of these could have resolved it) was got Polycom to send us new Power of Ethernet injectors. We also cleaned the wiring up from the POTS lines to the Adtran. Then from the Adtran to the T100P. We also, moved the server off of a Batery backup (cheapo) that seemed to be semi related. When we moved it onto the cheapo battery backup, we started noticing the static. So anyone of those seemed to resolve it. We also moved echo cancellation off of * onto a Tellabs box, and are much happier with the performance and cancellation. Best of both worlds I guess.
