Sip Paging: Multiple Speakers (Using Multicast) - Algo 8186 Installation/Configuration Manual

SIP Paging: Multiple Speakers (Using
Multicast)
Multicast features in the 8186 SIP Horn 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.
To enable multicast monitoring in the other speakers, go to the web
interface for each speaker and again navigate to the Basic Settings
 Multicast tab. This time though, choose multicast mode
"Slave/Receiver". There is no need to select a zone as the speaker
will automatically monitor the "All Call" zone IP address.
The page pre-announce tone is generated from the Master. The
following options are valid for each multicast Slave speaker:
Talkback can only be used for the SIP registered Master speaker.
When paging with talkback enabled, only the area near the Master
speaker is covered for talkback. The microphones in the
multicast/Slave speakers are disabled except for ambient noise
monitoring.
