Keeps calling and won't leave a message

Andover, MA. 6 Second's of silence on Voice Mail. Can somebody suggest a phone that can block more than 50. Reached my limit with cable provider.

I would suggest you do a search online as there are many choices of both telephones with built-in blockers and stand alone call blockers. Examine their capacities and features. Some of the telephones also have many other built in features (Talking caller ID, an answering system and so on). And what works for someone else may not work for you. http://800notes.com/nb/search?q=call+blockers
Good luck.

They called again today at 6:38 pm. This time their call was blocked by our call blocker. Please see my post of 4 Feb 2017.
