I thought thats how most providers operated? I have a smaller cable co for phone and internet. I purchased my own Motorola 6120 in 2010 when it was a new product.
I have Phone and Internet with my provider. They supplied an Arris modem that although could technically do both, it only does voice. My Moto does Internet.
I just have a package price for Internet/Phone plus tax. No equipment fees.
This is with Service Electric Cablevision.
I seem to remember Comcast was the same way.
