Okay to get calls from this number. It is a confirmation call from AT&T Residential Repair Service.

Got a call from this number. The caller left no voice message.

The announcement notified me that the changes to phone number ( then silence ) blah blah blah. For your reference use number ( silence ) and thank you for choosing AT&T......or something to that affect and then the message said that if I had any questions to call 1-877-737-2478.

I did not call back to a phone message that did not correcttly identify which of my phone numbers that was changed ( I have 4 ) or what the actual incident or trouble-ticket number was, so I had nothing to supply an actual AT&T rep if I did make that call.

Very odd....
