Multicast Paging
In addition to direct point-to-point dialing (peer-to-peer), directly or via a SIP server, each telephone is
capable of receiving a Multicast broadcast. Multicast allows a single audio stream to be sent to multiple
end points simultaneously, to achieve multi-point paging or Public Address functionality over IP.
Multicast requires the use of a SIP server or IP device that specifically supports Multicast functionality
and each telephone must be configured (enabled) to receive Multicast packets.
Tips for VoIP Subscribers
If you have or are thinking of subscribing to an interconnected VoIP service, you should:
 Provide your accurate physical address to your interconnected VoIP service provider to ensure that
emergency services can quickly be dispatched to your location.
 Be familiar with your VoIP service provider’s procedures for updating your address, and promptly
update address information in the event of a change.
 If your power is out or your internet connection is down, be aware that your VoIP service may not
work. Consider installing a backup power supply, maintaining a traditional telephone line, or having
a wireless telephone as a backup.
