Replacement for end-of-life voice modem

Xfinity is saying my current modem with voice won't get more security updates. So far I'm not finding any recent replacements, the Netgear CM2050V and Motorola MT8733 are the only ones I find with Voice on Xfinity's compatibility website, and from reading about either, the netgear is not sold anymore and the Motorola is old and isn't getting security support anymore.

I have the same issue.  The only Xfinity approved voice modems I have found are refurbished and from resellers that may not be trustworthy.  This also includes the Arris T25 which is also "approved".  I can't understand why Xfinity would call the CM20250V "recommended" on their page of allowed gear when it is not commercially available.

It does look like Xfinity has a rental modem with voice, but it wouldn't take many months until you've paid as much as new modem would cost.

Hey @user_w8tt5o , Thank you for visiting our official Xfinity Forums Community support page. We greatly appreciate you taking the time to reach out regarding the voice modem. I would be more than happy to offer my assistance, the list currently is here https://www.xfinity.com/support/articles/list-of-approved-cable-modems for approved modems. You are able to get a Xfinity gateway with voice capability on it. Most new plans have the gateway rental built into them, it is not an extra charge. If you would like us to take a look at the account for a gateway, let us know. We are happy to help.
