Caller hung up as soon as my automated voice mail started, guess it can't be that important!

no one speaks when i answered.

this phone number has called my cell more than once and no one is there. they just hang up

No one answers when I pick up the phone.

We have been called by this number several times. No one is there when we answer our phone, only silence. We waited until a weekend and blocked our outgoing CallerID while calling this number back. It answers immediately and then says something like "Our customer service department is closed, please call back 9-5 weekdays" and doesn't give us any chance to leave a message. Our opinion here is that it is either a telemarketer or an outgoing call center for another reason like credit/charity/survey. If it were an important company that wanted to talk to directly to us for a legitimate reason, other than solicitation, they would have done two other things: 1. They would have announced who they are. 2. They would have given us the opportunity to leave a message. Since these two things are not presented to us, this clearly says, in our opinion: They are not worth our time. Subsequently, we used our fancy-dancy system to take notice of their number and play the sound of jungle monkeys to them whenever they call back.
