Ensuring Call Completion

• IXCs must manage their suppliers
• Develop Industry Best Practices
• AT&T contracts with call termination suppliers include:
• No looping (can’t send traffic back to AT&T services – 
directly or indirectly)
• No actions to make traffic appear as other than US- 
originated long distance traffic
• No alteration of CPN or other signaling parameters
• No attempt to avoid access claiming TDM as “enhanced”
• Vendor must comply with all applicable laws
• Vendor must similarly bind any of its suppliers
• Vendor must indemnify AT&T w/r/t the above
• If vendor cannot complete, call must be cranked back to 
AT&T
• Specify & monitor DMoQs
