This is so funny the caller ID says east coast C U N T. I had to block these fools so the grand kids wouldn't repeat what they here on the answering system. Hers a solution that is working for me and no I don't work for Panasonic but this product delivers peace and quite: Our new Panasonic cordless phone system KX-TG465 w/link to cell can block 250 spammers including a rage of numbers like 888 or (877 you know switch your medicare insurance). The best part it was only $99 at the local wholesale club, that's cheaper than buying batteries for our old phones! OK chimney guy, medic alert guy, survey guy, Microsoft support guy, home security guy and every other B A S T A R D that rings phones at meal time and when you are asleep we are ready for you. It even has the ability to silence the first ring before the caller info is displayed. P:S: Let it charge up before attempting the blue tooth connection. Footnote: these crooks who want to clean your chimney are under investigation for not doing the work they charged for. Besides I already cleaned mine but I would love to clean their F U C K I N G Clocks for them.
