We are disconneting our Megacom Trunk group which carries our 800 numbers. We need to redirect the DNIS digits associated with these 800 numbers to another trunk group. I can not figure out how the system is routing the calls to the Megacom group. I have checked the Route patterns and even did a "list trace tac" to try and determine how the system is routing the calls. We have an Avaya Definity PBX system. Can someone please offer some assistance?
