repeated calls

I get about 1 call a day from this number. There is never anything when i answer. When I call back it is said to be an international call, regardless of it being a standard local area code number.

I've been getting a couple calls a day from this number also.  They never leave a message and when I answer, there is no one there.

same here, just about every day for the last 2 weeks.  Today it was 2 times.  And I can not call it back, rings once and a busy signal.

This number won't stop calling me (daily), but when I answer, no one is on the other end.

I have been getting calls from this number around three times a day for the past month. They never answer and I get the same thing when I call them back, it rings twice and on the second ring cuts out halfway between it and then goes to a busy signal.
