Who called from 8175879550

Said "Alvarado TX".  Rang and disconnected.  Guess we know what happened then.

Same thing- Caller ID says Alvarado TX but has area code of 817-587-9550.  Never leave messages.   Also uses 817-587-9546.

Calls and hangs up when answering machine kicks on, without leaving a message. Caller I.D. reads "Alvarado, TX  817-587-9550.  I have no way to block my landline unless I pay a fee of $9.00/mo, that's too much, so will ignore and shake my head..................
