Sip Paging: Multiple Speakers (Using Multicast) - Algo 8188 Installation/Configuration Manual

ALGO
If VLAN is used, navigate to the Advanced Settings  Network tab
to set VLAN options.
(Note, once the speaker is using VLAN you will need to be on the same
VLAN to access the web interface.)
The speaker may now be accessed by dialling its assigned extension
from a telephone, device, or client. The speaker will auto-answer, play
the default WAV pre-announce tone, and allow voice paging until
disconnected.
There are a number of configurable speaker options:
The best voice paging quality and intelligibility will be obtained using
the G.722 wideband audio codec. Most current IP telephones support
G.722 which is sometimes referred to as "HD" voice or audio.
SIP Paging: Multiple Speakers (Using
Multicast)
Multicast features in the 8188 SIP Ceiling Speaker require that only
ONE of the speakers be registered as a SIP extension. Additional
speakers may be added as multicast Slaves receiving a stream from
the SIP registered Master speaker. Please note that any number and
combination of Algo speakers, paging adapters and strobes can be
part of a multicast.
The Master speaker will page normally while simultaneously
streaming audio to the slave speakers. The Slave speakers do not
require SIP extensions and do not need to register with the SIP
Communication Server.
To enable multicast streaming from the SIP speaker, go to its web
interface and navigate to the Basic Settings  Multicast tab.
Choose multicast mode "Master/Sender" and zone "All Call". The
multicast addresses pre-populated in the table will work in most
cases.
