Go check out Johanne's Comcast Enters VoIP Market With Pricey Plans article.
She writes: "The company plans to charge customers $39.95 per month for unlimited domestic service to current customers of its video products, and a whopping $54.95 monthly for new customers. Most VoIP calling plans available to residential customers today average about $29.95 per month."
It doesn't appear that Comcast is discounting their VoIP plan even if you are an existing data customer and they slam you with $54.95 for new customers - OUCH! At least with Cablevision I determined they were indeed discounting if you went with their Triply Play package.
Perhaps Comcast is discounting if you purchase multiple services, but I trust Johanne did her research on this one and Comcast is not discounting.
This is a perfect lead in to a Triple Play article that I am writing as a cover story for Internet Telephony Magazine. I'll give a sneek peek at the article in the next day or so in my blog.
