user_mvh90p, Hi there! Thanks for reaching out. Yes, the Motorola MT8733 is compatible with Xfinity Voice services. It is an approved voice gateway that supports download speeds of up to 2335 Mbps, making it a solid option for customers looking to use their own equipment instead of renting an Xfinity gateway.

 

That said, compatibility can vary depending on your specific service level and account setup, so we always recommend checking your device on Xfinity's approved device list before purchasing or activating it here. If you'd like, we'd be happy to help verify compatibility for your particular services. 😀

Thank you both for the information.  I am also looking at the Netgear CM2050V.  That may be a current cable modem while the Motorola may be discontinued.
