AT&T BGP Setup

Hey everyone. I didn't really want to ask this out here, but wasn't sure who else I could ask, but does anyone here have BGP setup with AT&T as well as to other providers? Could you give me a phone number for a rep? Our AT&T reps are telling us they won't allow us to announce IP we get from AT&T and our own IP out our other connections, and vice versa where we cannot announce our IP address and IP addresses we have from AT&T out to through their circuit via like an Optiman setup. So basically, if you have a rep that some answers, could you forward me their phone number off-list? Thanks! -S
