we're getting frequent calls from this number. sometimes it goes to voicemail but no message is ever left.  very irritating.

I've received a few calls from this number as well.  Someone should discontinue that number.  I pick up the phone and someone just hangs up and that's it.  Very frustrating.  Very immature as well.
