What is the major difference of sending an 800 number over a PRI piggy-backed to a DID or sending DNIS? I understand that in all cases without DNIS, dedicated access is not an option. What if I had the 7 (800) numbers in our office sent down our T1 pipe with DNIS? How do I program my Definity G3iV3 to accept DNIS and send it to the appropriate hunt group? Or better yet, what will I gain other than Dedicated access?
