Sip Paging: Multiple 8180S (Using Multicast) - Algo 8180 User Manual

In the diagram above, the bottom 8180 is configured with a SIP Page Extension. When
called from a phone, the SIP registered 8180 auto-answers and plays the page audio over
its speaker. Simultaneously, the registered 8180 endpoint broadcasts the audio over the
network using RTP multicast to any number/combination of Algo IP speakers, paging
adapters, and strobes as required.
The registered 8180 (i.e. bottom of illustration) is the configured as multicast Master and
the top 3 endpoints are multicast Slaves. 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 8180s (Using Multicast)

Multicast features in the 8180 SIP speaker require that only ONE of the speakers be
registered with 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
zone.
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.
