An RGTS PRI circuit delivers a variety of performance capabilities not available with individual dedicated voice and data lines:
Direct Inward Dialing
Outsiders can call internal extensions directly, without having to go through a PBX Auto-Attendant.
The unique number for each extension can be displayed on outgoing calls. Call-center applications can use the unique caller ID number to differentiate various services.
Any designated phone on any free channel can receive multiple incoming calls to a general number. Busy signals are avoided or eliminated.
Flexible Billing options are available. For example, billing can be itemized by department.
