Matrix PRASAR UCS - Paging

Matrix PRASAR UCS System Manual 991
Paging
What's this?
Paging allows you to make announcements to groups of extension users and to make public announcements over
a public address system. You can deliver a message to a mass of people at once by just lifting the handset of your
phone and dialing a code.
This feature is useful when you want to call several people at once; for example, to inform them about a meeting
you have scheduled. If the persons you want to call have Matrix Extended IP Phones or Standard SIP Phones as
their extensions, you can use paging instead of calling them up one by one.
PRASAR UCS supports paging where announcements are made on SIP extensions.
The extensions which are to be paged must be included in 'Page Zones'.
• You can start paging from any SIP Extension and the paged extensions must also be an Extended IP
Phones or Standard SIP Phones. The Standard SIP Phones on which you are paging must support
Call-Info or Alert-Info header for Paging.
• When the Paging call is generated in SIP Extension having multiple call appearance and already a call
is present on the SIP Extension then the PRASAR UCS will place the Paging call as normal call on the
SIP Extension (as headers required in INVITE for paging call and intercom call are same).
• Paging is a one-way communication. As the mic of the paged extensions is muted during Paging, the
users of the paged extensions cannot speak to the paging extension.
How it works
The Pre-requisites
• Page Zones must be created. Each Page Zone accommodates up to 32 SIP extensions. You can create
12 different Page Zones of 32 SIP extensions.
• Paging must be enabled in the Class of Service allowed to the SIP extension from which this feature is to
be used.
The Process
• A user of a SIP Extension having Paging in its Class of Service, dials the Access code for Paging and the
Number of the Page Zone to which the user wants to make the announcement.
• The system activates the speakers of the SIP Extensions programmed in the Page Zone number. The
system activates the speakers only of those SIP extensions in the Page Zone that are free.
• The calling SIP Extension user makes the announcement.
• All SIP Extensions in the Page Zone can hear the announcement. But as the mic of their phones is muted,
their speech will not be heard by the calling SIP extension user.
