Simultaneously, the registered 8301 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 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. 8190, 8186, 8188, 8128, 8201,
8301, and 8373).
SIP Paging: Multiple 8190s (Using Multicast)
To use 8190 multicast feature, setup an 8301 Paging Adapter & Scheduler (sold
separately), as a Multicast master.
The Master device 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 8190 Paging Adapter & Scheduler 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 8190, 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)
•
SIP Paging: Multiple Speakers (Using Individual SIP extensions)
In some cases, it may be desirable for every speaker to have a SIP extension. Multicast
may still be used to page multiple speakers but each speaker can also be called
individually or generate a call when appropriately configured.
A speaker configured as a SIP Multicast Slave will give its highest priority to the 'Priority
Call' zone. Other than the 'Priority Call' zone, a page using its SIP extension, has priority
over all other multicast zones.
Communication Servers with the capability of dialing many SIP extensions simultaneously
for paging may be able to create zones by calling "page groups" and also page telephone
speakers in conjunction with overhead speakers.
