I manage a Meridian PBX at a Corrections Facilities, a Meridian with option 11C. We have a trunk line set up to feed tip and ring to a Valcom paging system. Is there a way to set up certain Dn's within the system to be able to do emergency break in to paging in case of an emergency. We currently use a two digit paging access code (i.e. 60 thru 69) 60 is our all call with 61 thru 69 giving us our zone coverage thru out our facilities.
