INTRODUCTION
Multicast paging is an approach to let different SIP users to listen to a page from a common multicast IP
address. In multicast page call, one way audio will setup from sender to listeners, but the listeners cannot
talk to each other. The sender and listeners must be located within the same LAN.
GXP2130/GXP2140/GXP2160 supports multicast page sending and listening on firmware version
1.0.4.10 or greater. Users could configure line keys or multi-purpose keys to send multicast paging. Also
GXP2130/GXP2140/GXP2160 is capable to listen to at most 10 different multicast addresses by following
defined preference.
This document serves as an end user guide on how to configure multicast page on the
GXP2130/GXP2140/GXP2160. To learn more about GXP2130/GXP2140/GXP2160's basic and advanced

RECEIVING MULTICAST PAGING
CONFIGURATION
To receive multicast page, GXP2130/GXP2140/GXP2160 must be well configured to listen to the right
address and port. The configurations are under Settings->Multicast Paging. There are 10 listening
address supported with priority levels 1 to 10. Optionally, each of these addresses can also have a label
that will display on LCD when the page is received.
Note: The multicast page configuration requires rebooting to take effect.
Figure 4 Multicast Paging
Table 1 Receiving Multicast Page Configuration
Settings -> Multicast Paging
Paging Barge
Default setting is “Disabled”. Assigns any number from 1 to 10. When
enabled, during active call if incoming multicast page is higher than this value,
the call will be held and multicast page will be played.
Paging Priority
Active
Default setting is “Disabled”. If enabled, during a multicast page if another
multicast is received with higher priority that one will be played instead.
Multicast Paging
Codec
The codec for Multicast page sending. The default setting is PCMU.
G.729A/B, PCMA, G.726-32 and G.722 (wide band) are supported as well.

Multicast Listening
Support 10 of listening multicast address with priority levels 1-10 with 1 being
the highest priority. The lower the level, the higher the priority.
PAGING BARGE
This option is to control the priorities between multicast page and common SIP call. Available options are
Disabled and numbers 1 to 10. If the option is set to disabled then all incoming pages are ignored while
in call.
When the option is set to number, Paging Barge is enabled. If the number of Paging Barge is higher than
an incoming page’s priority value (determined by the position in the list 1-10) then the incoming page is
not played. Similarly, if the Paging Barge value is lower than an incoming page’s priority value, and then
the active SIP call will be held.
As an example, in Figure 3, the Paging Barge is configured as 3. During an active call if incoming
multicast page priority is greater or equal to 3, the current active call will be held, and page will be played.
However, if the incoming multicast page priority is 1 or 2, the current active call will be kept.
PAGING PRIORITY ACTIVE
This option is to control the priorities among different multicast pages. If the option is disabled, the phone
ignores any incoming pages when a page is already being played. Otherwise, incoming pages with a
higher priority will be played instead of the current page. For example, if the phone is playing a page
whose priority is 5 and there is an incoming page with priority 3, the priority 5 page will stop and the
priority 3 page will play instead.
RECEIVE MULTICAST PAGING CALL
After multicast page listening well configured, please reboot the phone to let the settings take effect.
When there is a page on the listening address and port, the phone will play the incoming audio
automatically. User can press “EndCall”softkey to end the page.
