I got a call from this number too. I have blocked similar calls and similar numbers before in the past that do this, but then they find a new number to call from. It's very troublesome. When it's a local number, I never know if it's a client or colleague so I can't just avoid it.
Someone calls from this number MULTIPLE times a day even though they have been asked repeatedly to remove our number from their call list. You cannot call them as it rings once then goes to a busy signal. This is harassment sales at its worst.
