A:AnswerI was able to get the modem and router set up with Spectrum without any issues. I had to use ethernet cable first to go through the setup but Spectrum activation portal read it immediately and walked through the setup. I had to enter the CMAC # and then Spectrum ran a query and connected without issue. However, I have not been able to use the telephony connections with Spectrum at all. I had to use a splitter and connect the voice service back to the old modem. I'm going to call Spectrum to see if they can do some setup on the voice service so I can return the old modem back to them.
But the speed is great on the internet signal.

A:AnswerI can't answer the first question, but to the second, it is an Internet + voice modem and router combined. Check with your ISP to find out whether it will work with your service.
