no one there when you answer.
This has been about the 3rd call within a week or less. Caller ID has American Alarm but it does not ring long enough for answering machine to pick up. Probably a telemarketer but inconvenient to say the least.
Phone call from American Alarm. Did not answer and caller did not leave a message on the answering machine. Assume that this is an alarm monitoring company that wants to "give" me a free alarm system and charge me for monitoring it. Telemarketer. Put them on the call blocker.
