Make sure the remote phone is using a low bandwidth codec too. In a previous life changing a remote (home) user's phone from G.711 to G.729 made all the difference in the world to their call quality.

Have you monitored your user's home Comcast connection with regards to packet loss or latency, preferably from network-near the SIP termination point?

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.
