It happened again yesterday....my brother told me thats what my phone said when he called me. He was able to redial and it went thru the second time. My hubby had the same thing happen to him about a month ago. He said he had to dial me several times before it went through. I wonder how many other times this has happened that I don't know about. Verizon told me just to shut it off and turn it back on....working Ok again, but sometimes I leave my number for a person to call me that might not know its a glitch... (I don't have any numbers blocked on my phone) Any ideas?
