What product options does AT&T wholesale have for SIP Origination and Termination? I assume the offer on-net DID's in most all the markets that they are able to offer cellular number right? Do the SMS/MMS enable their DID's? Are they competitive compared to the usual Bandwidth.com and Level3 options? Do they offer an API for porting and number inventory?
