Hello--i'm in the process of configuring a new CUCM Business Edition system at a company with multiple locations. Between two of their locations, they have a T1. They've got a device breaking-out the T1 for audio (radio station) and 4 OPX lines (two down to the other location, two coming to the main site). They have an old TDM system currently where they dial a code, and they grab dial-tone at the far end, and vice-versa. I'm trying to figure out how to configure the cisco voice gateway at the site getting the CUCM to allow this functionallity. The other site is keeping the old TDM system in place. Any help is greatly appreciated. Thanks.
