I'm 94 years old. At my age it's (WHO RA, RA ) when the phone rings and leaves no message or name... My two dogs and me know it's treat time, we run to the kitchen. They sit up for a treat and i put on my Sherlock Homes cap, Then grab my big spy glass and search the internet for the number who called me. Phone number 1-405-283-8653 NO NAME OR NO MESSAGE ! I love it , at my age a phone call is a treat instead of a TREATMENT... I'm proud to know that i have solved 98.9% of my unknown phone calls threw the Internet and people like you. ( THANK YOU ) PS. You'd be proud too. All i can say.plus my 2 dogs of course,is (KEEP MY PHONE RINGING WE LOVE IT )
