I get this at the same time several times a week. We let the answering machine do it, never any message. They are a pain!

Quit drivin' me nuts.....you call when I'm in the middle of making supper...go away

Left voicemail Aug 31, 05:12 PM, caller said "hello ... hello" and hung up. A lot of background noise as if from a very busy call centre.

My VOIP service adds the city for calls that come in with no name in the caller ID and this showed "ETOBICOKE ON".

Called would not leave a message or name on display.

it's MADD..(mothers against drunk driving) under another guise.
