Hi Steve,

The RF is probably getting into the normal telephone after the Comcast 
modem.  I would try a filter between the modem and the phone.  Enclosed 
is a schematic of a filter that I have good success with.  I have one 
that I am not using at the moment that I could mail to you if you want 
to try it.
