Sip Paging: Multiple Speakers (Using Multicast) - Algo 8188 User Manual

Multicasting can also be used to distribute loud ring or other alerting (e.g. safety, security,
or emergency events) over multiple Algo endpoints (e.g. 8180, 8186, 8188, 8128, 8201,
8301, and 8373).

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 multic-
ast.
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 Advanced Settings > Ad-
vanced Multicast tab 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 talk-
back enabled, only the area near the Master speaker is covered for talkback. The micro-
phones in the multicast Slave speakers are disabled except for ambient noise monitoring.
Note: See "Basic Setting Tab – Multicast" section bellow for more configuration op-
tions and instructions.
