Compatible Call Blocker Devices?

Compatible Call Blocker Devices?

I get more robo calls and annoyance calls than the COMCAST call blocking can handle. I’m interested in purchasing a call blocking device to supplement the COMCAST service but most say they don' work with COMCAST. Do you know of any devices that are compatible with my COMCAST voicemail system.

Did you ever find a solution?  I'm looking for the same thing.

I purchased this as my main cordless phone & also bought an extra handset. The phone can block up to 250 numbers.
