Who called from 4165563211

Was woken up on Sunday morning by a call from 416-556-3211 with no message left. Called back and got a recorded message that the call cannot be completed as dialed and to check the number. About 5 minutes later received another call from 416-556-3211. Called back again and got the same voice message that the call cannot be completed as dialed. Most likely the call came from some scammer using outgoing only lines...

Just arrived home from the cottage. Had three calls from this number since Friday night and no voice mail. Cannot call back, number is not in service.

Just received three dead air calls from this number, the last at 7:05 AM. Most likely some fax machine calling on redial
