Comcast Phone

Has anyone had a surge burn out BizPhone 3 phones on Comcast telephone service. I've had this phone system on Verizon for 15 years. When I switched to Comcast, all the phones that were set to ring burned up, and the ones that were set to not ring, did not. When I move one from a non ring location to the ring location, it burned up as well. Can the ring from a comcast voice modem cause a surge that can burn up the phone chipset? What kind of surge protection will work?
