This has nothing to do with Vonage and likes that market to consumer - their
devices are locked so the consumer is locked into the services that
Vonage/MagicJack/etc provides. They are not the companies that are going to
eat lunch of cable companies and old school telcos as their business model
is to sell the same servie at a minimum discount to the rates of dominant
carriers.

What the cable companies are afraid of is that when a consumers have SIP
speaking devices used to terminate calls the consumers will find VOIP
providers that charge $1.00 a month for a phone number and another $0.01457
per voice minute with 6, 5, 4, 3, 2 or 1 second billing. After deploying
about nearly a thousand SIP-speaking phones for different folk over last few
months I can tell you that the self-provisioning for the customer's side is
becoming so easy a caveman can do it. 

There goes their $20 or more per month worth of profit per phone number.

Does it mean that they are preventing other SIP devices to work on their
IP network? No, it does not. But what they are doing is preventing SIP
devices from working with their voice network because they do not want it to
be a user-controlled SIP device.
