Of course, Comcast sells its own VoIP services, which I'll bet work just
fine; so they don't have a huge incentive to go out of their way to make
their competitors' product work on their network.

Very little incentive to fix it. The number of customers that are able
to switch providers when something like this doesn't work is a
fractional percentage of overall customer churn.
The MBAs say it's cheaper to ignore it, so that's how it goes.
