ShoreTel 14.2 Planning and Installation Guide 159
Overhead Paging
The ShoreTel system can provide single-zone overhead paging for each site by using the audio output
port on those ShoreTel voice switches that provide an audio output port.
For sites that require overhead paging, you must designate one of the ShoreTel voice switches to
provide paging. In addition, you must provision your selected paging equipment for connection to the
ShoreTel system.
Multi-site Paging Groups
As an alternative to a paging system, you can designate groups of system extensions that can be
paged by dialing a single system extension. In this way, audio is routed to a group of phones and
played on the phone speaker as opposed to playing the audio announcement on an overhead paging
system.
You can also add a paging extension, which is associated with a site’s overhead paging system, to a
paging group in order to simultaneously play audio on a group of phones and also an overhead paging
system. Refer to the ShoreTel System Administration Guide for details.
