Any chance someone on this list is affiliated with Comcast who could contact me off-list? I have an employee in Virginia who works from home using, in part, a VOIP desk telephone tied into our office phone system back in Nebraska. She's had nothing but problems maintaining a stable connection and I'm at my wit's end to diagnose and fix whatever is causing her problems.
I've got this exact setup with several employees around the country, but this one person is the only one who, 1 - has problems and 2 - has Comcast.
Much appreciated!

I have found Comcast rate shapes or resets long running encrypted sessions such as https. At $DAYJOB I had to set our SSL VPN system to re-key via new-tunnels every 5 minutes to keep it under their threshold of what looks like seven minutes for a tcp session. After that the sessions appeared to rate shape down to 128kbps. It may also only kick in during local POP congestion. I am assuming this is DPI trying to do peer-2-peer mitigation. --- James M Keller
