Home Phone (Landline or Digital Voice)

[#1]

We use fios tv/internet/phone package and recently almost every day we got 2 or 3 times phone calls from the same wireless phone number we do not know.  When we pick up the phone to answer, the caller makes no sounds and we have to hang up.  It is very annoying.  Is there a way that we can block this person phone number so that he/she can not bother us anymore?

THere is a service you can subscribe to, not sure what the name is right now, but if you call the billing office and tell them you are getting harrasing calls, they can put a block on it.

Some of the services like FiOS digital voice, the Hub or I think the old IOBI let you block up to 5 or so numbers so it shouldn't be a big deal.
