Multicast Paging User Guide

GRP26XX

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 Carrier-

Grade 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

http://www.grandstream.com/support to download the latest "GRP26XX User Guide" and "GRP26XX

Administration Guide".

Keys →Virtual Multi-Purpose Keys.

Set the key Mode to Multicast Paging in dropdown list.

Enter the multicast paging description in Description field.

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 Multi-

purpose keys to multicast page sending key.

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.

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

RECEIVING MULTICASTPAGING

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.

GRP26XX

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.
