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 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.
