INTRODUCTION
Multicast paging is an approach to let different SIP users 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.
GRP26XX phones support multicast page sending and listening on firmware version 1.0.0.31 or higher.
Users could configure line keys or multi-purpose keys to send multicast paging. Also, GRP26XX CarrierGrade IP Phones are 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 GRP26XX
Carrier-Grade IP Phones. To learn more about GRP26XX's basic and advanced features, please visit

Administration Guide".

SENDING MULTICAST PAGING
Configuration
Sender multicast page configurations are under GRP26XX’s Web UI → Settings → Programmable
Keys → Virtual Multi-Purpose Keys.
1.
Set the key Mode to Multicast Paging in dropdown list.
2.
Enter the multicast paging description in Description field.
3.
Enter multicast paging address and port in Value field.
The range of multicast page address is 224.0.0.0 to 239.255.255.255 with a port not in use by
phone.
The Figure 1 and Figure 2 show the example of setting Virtual Multi-purpose Keys/ Physical Multipurpose keys to multicast page sending key.

Notes:
• GRP2614 supports MPKs under Web UI Settings → Programmable Keys → Physical Multi-
Purpose Keys.

• GRP26XX supports 6 codecs for Multicast Paging. Users can specify the multicast page sending
codec under Web UI → Settings → Multicast Paging → Multicast Paging Codec.
• The supported codecs are PCMU, G.729A/B, G.723.1, PCMA, G.726-32 and G.722.
Send Multicast Paging Call
After configuring the sender multicast page, users could make a multicast page to remote parties.
1.
Press the configured MPK or Line Key to send a multicast page.
The LED light of the key will turn green and the phone screen will show the multicast address with
defined label. See Figure 3 Multicast Page screen.
2.
Press the “EndCall” soft key to end the multicast paging.

RECEIVING MULTICAST PAGING
Configuration
To receive multicast page, the GRP26XX must be well configured to listen to the right address and port.
The configuration is set up under Web UI → 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.

Paging Barge
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. Default setting is “Disabled”.
Paging Priority Active
If enabled, during a multicast page if another multicast is received with higher
priority that one will be played instead. Default setting is “Disabled”.
Multicast Paging
Codec
The codec for Multicast page sending. The default setting is G.722.
G.729A/B, PCMA, G.726-32 and G.722 (wide band) are supported as well.
Multicast Channel
Number
Multicast Channel Number range is 0-50. 0 for normal RTP packets, 1-50 for
Polycom multicast format packets.
Multicast Sender ID
Outgoing caller ID that displays to your page group recipients (for multicast
channel 1-50).
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.
