Received call at 1944 (744 pm) xmas eve.  Too busy (BY) to answer it.  Tried trace but to no avail.  When called mid day 081230 I just got dial tone.  (perhaps a fake dial tone, and was it collecting my calling number?)

this number called 4 times this morning, with in 3 hours.. i answered it twice and both time there is a woman speaking mandarin to me and mentioned something about some survey.. i told them i dont understand mandarin and i hung up.

this number has called twice in the last hour

Got a call from this number at 6am. It just left beeps on my machine, this has happened quite a bit. I come home, and find beeps on my answering machine.Can't something be done?

missed a call from it during sleep. called back but always busy.
