I've gotten an amazingly few calls since putting the CPR202 on my phone... so that's cool. I HAVE gotten a few, and have tried #2 from my handset, but the call doesn't hang up, and the device does not show an increment in the number blocked. So yesterday and today, I have gone out to the device itself and pushed the Block button, and get the same effect. The only thing I can think of is both of those showed "Unavailable", and I do not have the generic "Unvailable" blocked because friends of ours have their phone set to 'private'. Is that going to keep me from individually blocking calls?
