It's in the triple play bundle - think it comes to $37 plus equipment rental. Call it $45. I pay another fee for unlisted number. Long distance unlimited nationwide blah blah.
I really like the VOIP features, all the stuff you can manage online instead of cryptic button mashing. Call blocking and call ID on TV are my favorites.
Top quality wiring is essential to reliability. Comcast replaced all the older coax in the house when it was installed. I've had 3 differnt Arris EMTAs (402, 702 & 722) and they were all reliable.
