First day for this call.  Did not answer.  I have robocall software.  Generally get one ring.  That is what happened today.  I did a quick search on the internet.  Did not get any other info.  I am at my blocked calls limit with Verizon and on my land line.  My phone however will save over 3000 contacts.  Now I am saving the spam calls and putting names on them, charity scam, FOP, cruise scam, etc.  If they call incessantly I delete an old blocked number and insert the new.  I have a Comcast number that I have never been able to use because of the never ending spam and collection calls.  I never gave this number to anyone so the people calling or not looking for me.  I tried answering and informing the callers that they had the wrong number but the calls kept coming.  After the first 3 weeks, I asked for a new number, had it unlisted, but the same thing.  Now it is hooked to my printer and used as a fax machine
