I was inundated with junk calls that read UNKNOWN in the Caller ID with calls coming into Google Voice. That was driving me nuts. Three, four, eight times a day those calls would come in, and I’d just ignore them.
Fortunately, my Google Voice number is the one that I publicize. I’d tried the Block function for the caller, but it didn’t work at all.
Here’s what did. Here’s what did. I went into Google Settings and changed the option for anonymous callers. When the anonymous call comes in, Google Voice has no phone numbers to forward the calls to.
