System Requirements and Limitations
RED ALERT VoIP telephones require PoE (Power-over-Ethernet) or a local 24 to 48-volt dc power
source for operation. Two VoIP telephones can be connected in a peer-to-peer configuration without the
need for a LAN. A 10/100 BaseT Ethernet network with a SIP (Session Initiation Protocol) server is
required for systems containing three or more VoIP telephones. Conferences are limited by the
customer’s LAN media capabilities and the services available at each end point.
These telephones also receive multicast broadcasts. A multicast audio stream is 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 that specifically supports multicast functionality and each telephone must
be configured (enabled) to receive multicast packets.
