I know I've done this before but for the life of me I can't remember how; I have a range of extensions (2xxx) at a remote site connected to our Definity through a tie trunk. When the trunk is down (fairly often) the switch routes these calls through the PSTN. I need change where these calls get routed to and I can't seem to find the right config screens. I don't think it's ARS as the numbers are in the dial-plan as local extensions.
Thanks for any help
