Sip Paging: Multiple 8186S (Using Multicast) - Algo 8186 User Manual

to any number/combination of Algo IP speakers, paging adapters, and strobes as
required.
The Slave endpoints require a PoE network connection but do not require registration to
the communication server.
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 8186s (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, under Advanced
Settings > Advanced Multicast section, will work in most cases and should only be
altered for rare 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:
• Increase or Decrease Speaker Volume
•
Enable Ambient Noise Monitoring (speaker volume adapts to background noise)
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.
Note: See "Basic Setting Tab – Multicast" section bellow for more configuration
options and instructions.
