Nuisance phone calls are a real problem and will eventually cause me to drop my landline altogether; so, I have a suggestion for Comcast: Increase the number of calls (phone numbers) that can be blocked from the current 25 to 500 or so. It would be a good service at little to no cost to Comcast.
Try using Nomorobo. It is compatible with Xfinity and works great for blocking spammers and robocalls.
Glad to hear this is working for you, @Gene76!
