mediacom modem replacement

[Skids1]

A friend of mine has a Mediacom CM4652442-MM all in one modem\router\phone box.   Are they able to replace it with a Arris Surfboard T25 device and still use their mediacom phone service?  https://www.amazon.com/ARRIS-SURFboard-T25-Certified-Internet/dp/B07MGPPNZD/ref=sr_1_3?crid=3J0YR3B0...

Attached link of device in question?

@Skids1 Mediacom VOIP phone service is not supported on modems other than those issued by Mediacom. There is a slim chance it might work, but they will have to test it themselves.
