I switched to the combined cable (TV) /phone/Internet service about 3-4 years ago. Was paying $70/month for 512M internet and analog cable then $40 to the phone company for a land line without even long distance. Cable company offered their deal of phone service with unlimited long distance, digital cable, one receiver and 2M internet for $89 so we switched. Added another receiver and upgraded the other to a DVR but still under $100 before taxes.
Their phone service is not IP based, its layer two (datalink), really just another mux'ed channel like the cable so it doesn't suffer from any of the QoS services that VIOP had. We have had much better service from them then the phone company who became part of AT&T and then we had outages and dropped calls all the time (yes dropped calls on a land line).
