Telephony modem

[flashman2]

I use one cable modem for telephony and another cable modem for internet/cable. I want to replace my rented Comcast telephony modem with a Comcast improved one that I will purchase. What is the step by step procedure to swap out the telephony modems?

See the following link for list of telephony modems and setup procedure:

Since that message was created there is now a Netgear CM1150V docsis 3.1 modem that is retail approved
