Hi there! I see you're having trouble getting Nomorobo to work with your Xfinity landline. Can you tell me a bit more about the issue? For example, is Nomorobo not blocking any calls, or are you having trouble setting it up? Also, is your landline a traditional phone line or a VoIP (internet-based) service through Xfinity?

Meanwhile, here are some general steps we can try to get this working:

1. Verify Advanced Call Forwarding Setup: Nomorobo relies on a feature called Advanced Call Forwarding from Xfinity to route calls. Make sure this service is active on your Xfinity account. You can enable it through the Xfinity app or by calling their Advanced Technical Support.

2. Check Nomorobo Activation: Log in to your Nomorobo account at nomorobo.com/signup, choose Internet Landline, select Comcast as your carrier, and ensure your phone number is properly added and verified.

3. Set Forwarding Number Correctly: When setting up, you usually forward your calls to a specific Nomorobo number provided during the setup. Ensure this forwarding number is properly entered in your Xfinity call forwarding settings.

4. Use the Xfinity App for Configuration: Some users have found better success setting up Advanced Call Forwarding through the Xfinity mobile app rather than the website.

5. Confirm No Conflicting Features: Features like call forwarding or blocking already set on your Xfinity account might interfere. Review your phone settings on the Xfinity portal or app to clear any conflicts.

If these steps are unclear or you’ve already tried them, please let me know, and we can go deeper or I can guide you on contacting the right Xfinity support team to check your account settings specifically for Advanced Call Forwarding.

Does this match what you've tried so far, or can you provide any additional details?

It's been working for a couple of years and we have made no recent changes. Did your system change? Would setting up our new TV be a likely problem?

Thanks for sharing those details! Since Nomorobo has been working for you for years with no changes on your end and only recently stopped, it’s less likely that the core Nomorobo system changed on its own. However, sometimes carriers like Xfinity do update their network settings or services, which can affect Advanced Call Forwarding, the key feature Nomorobo depends on.

Regarding the new TV setup, it's a good thought because some digital home phone systems and devices like TVs with voice or phone features can occasionally interfere with phone line settings—especially if your phone is connected through a shared device or if call forwarding or other features got impacted during that setup.

Here’s what I recommend you try next:

1. Check Advanced Call Forwarding Status on Xfinity: Sometimes Xfinity may disable or reset Advanced Call Forwarding accidentally or during service updates. Log into your Xfinity account or call their support to confirm that Advanced Call Forwarding is still enabled and forwarding calls properly to your Nomorobo number.

2. Review Simultaneous Ring Settings: Nomorobo requires “Simultaneous Ring” to be ON with the Nomorobo number listed. If this was altered or disabled—sometimes device setups can trigger such changes—Nomorobo won’t work.
- You can verify this by logging into your Xfinity Voice settings and ensuring Simultaneous Ring includes the Nomorobo number.

3. Test Your Phone Line Independently: Try plugging a standard phone directly into the main phone jack to verify the line is working fine. Sometimes new TVs or devices can cause network or line interference.

4. Reboot All Devices: Power cycle your modem, phone adapter (if VoIP), and any connected devices to refresh the network and line connections.

If everything above looks good and the problem persists, it’s worth contacting Xfinity support to ensure no recent network or account changes affected your forwarding or voice services.

If you want, I can guide you through checking Simultaneous Ring and call forwarding settings step-by-step for your Mac environment—just let me know!

Are these steps something you’d like help with?
