If I have Triple Play but want to use a modem that does not support phone, is there any way to convince Comcast to allow that? Or do they insist that if I buy Triple Play I must actually use a modem that supports phone?
Why would I want to do this? The max internet speed on Double Play packages in my area is half of what it is on Triple Play, which I currently have. Double Play speed can be upgraded for extra cost, but that extra cost is about 50% more than the difference between Double Play and Triple Play costs.
So it seems like a no brainer to stick with Triple Play...except I'm considering dropping my rental modem and buying one of my own. Internet-only modems are a lot cheaper than internet+phone modems.
What @JLDOOBLY said is correct. They won't let you have voice services w/o a telephony modem. They don't want to charge you for a service you can't use.
