Spam Calls on my Voice Line (Not mobile line)

Comcast can already identify spoofed caller IDs because they don't have the 'V' (for verified) by their number.  The filters provided to block potential spam calls are good but they need one more addition.  They need to block unverified calls.  Let me give you some numbers on a recent analysis I made from my own phone log.  I dumped a month's worth of my call log into Excel.  I received over 500 total calls that month.  With the filters already in place 27% were blocked.  If I had been allowed to block unverified calls, that percentage would have risen to 93%.  That's a HUGE improvement.  It can't be that hard.  As a professional programmer, writing code for 50+ years you already have something very close.  Somewhere you have a statement that looks something like this: If block anonymous=true & current call=anonymous, block it.  All you need is this statement: If block unverified=true & current call=unverified, block it.  One of the concerns about overly aggressive blocking is missing a legitimate call.  Of the unverified calls in my data NONE of them were legitimate.

Thank you.

Thank you for taking the time to share such detailed feedback and analysis. We can see you put a lot of effort into reviewing your call logs, and the data you provided does a great job showing how helpful a feature like blocking unverified calls could be. You make a strong point especially since the verified indicator already helps identify which calls may be more trustworthy.  While we don’t have a way to confirm new feature changes from here, we absolutely appreciate you sharing this idea and the real-world impact it could have. Feedback like this is helpful, especially when it includes both the reasoning and supporting data behind the request.

@XfinityKam​ I have been asking for call blocking enhancement for years now. Since spammers starting spoofing unique local phone numbers in caller id, the blacklisting feature is useless. Couple that with a questionable SPAM detection system and the whole blocking system has little value.

We need to add a 4th entry to the spam list for unverified calls and how to handle them. Then add a whitelist feature to catch the few legitimate non-verified calls and you have a system that will work. At least until the spammers figure out how to spoof the verified flag; which of course means not using the text in the name part of caller id as a means of detecting verification.

At the least, give us an option to force unverified calls into one of the spam catagories.
