Is Xfinity app required to activate phone service on new modem

Thank you for creating this post, @user_3f8zrp. I'm sorry to hear about the trouble you've had activating your Voice service on the new modem, and I'd love to see what we can do to help! There may be a way to do this without the app. Here are some steps to try:

1. The Web Activation Portal
We maintain a legacy activation website designed for browsers. Even if your modem is redirecting you, try forcing your browser to this specific URL while connected to the new modem's network:

- URL: xfinity.com/activate

If you are redirected back to the "Download the App" page, try accessing this link via a desktop/laptop browser rather than a mobile browser. If that fails, move to the next step.

2. The Automated Phone System (The "Walled Garden" Bypass)
Since your Voice line isn't working yet, you'll need to use a friend's phone or a work phone. We have an automated signal-sending tool that can trigger the provisioning for both internet and voice.

- Call: 1-800-XFINITY (1-800-934-6489)

- Method: When the automated system asks what you're calling about, say "Activate my modem." * The Goal: The system will usually attempt to send a "refresh signal" or a "provisioning signal" to the MAC address associated with your account. Once the modem receives this, the Voice light (Tel 1) should eventually go solid.

3. Direct Tech Support (Manual MAC Binding)
If the automated system fails, you'll need one of us to manually input your modem's CM MAC address into our provisioning system.

- Let us know if the above steps do not work, and we'll send you instructions for how to reach us directly.

Why the "Download App" page appears
The modem is currently in a "Walled Garden" state. It has a connection to our head-end, but it hasn't been "whitelisted" to allow general traffic or voice protocols. Once the MAC address is successfully registered on your account through any of the methods above, that redirect page will disappear, and your Voice service will initialize.
