Paging
Paging allows you to make announcement to a group of extension users by just lifting the handset of your phone
and dialing a code. In this way you can deliver a message to a mass of people at once.
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 the Matrix Extended IP Phone, or any Open SIP Phone as
their extensions, you can use paging instead of calling them up one by one.
• You can start paging from SLT or any SIP Extension. However, Paging is possible only on SIP
Extensions, which may be Extended IP Phones or Open SIP Phones. The Open 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 SARVAM 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. You can create 12 different Page Zones.
• The SIP extensions which are to be paged must be included in the Page Zones. You can create 12
different Page Zones. Each Page Zone accommodates up to 16 SIP extensions.
• Paging must be enabled in the Class of Service allowed to the SLT and SIP extension from which this
feature is to be used.
The Process
• A SLT/SIP extension user having Paging in the Class of Service, dials the Access code for Paging and the
Number of the Page Zone to which s/he wants to make the announcement.
• The system hunts for the IP Phones in the Page Zone which are free and activates the speaker of these
SIP Phones.
• The calling SLT/SIP extension user makes his/her announcement.
• All SIP extensions in the Page Zone can hear the announcement. But they cannot speak to the calling
SLT/SIP extension user, as the mic of their phones is muted.
• To answer the Paging call the desired extension user must use Meet Me Paging while the Paging call is
active. For details refer, “Meet Me Paging”.
• If no reply is received via Meet Me Paging, the calling SLT/SIP extension goes ON-Hook after the
announcement.
