After porting our number, people in our local area with AT&T service can't call us
We ported our number (Land Line) away from AT&T on Dec.15th. We switched to a VoIP provider and now none of the people in our local area with AT&T service can call us. AT&T said the issue was with the new carrier so we ported to another VoIP provider and we have the same results. The new VoIP provider would like to setup a vendor call to get this fixed but I'm not sure how to go about this with AT&T. Every time I call AT&T I get bounced around for several hours. Any ideas?
