System Requirements and Limitations
RED ALERT VoIP WiFi telephones require a 24 to 48-volt dc power source for operation (24 V dc
supply provided). Two telephones can communicate wirelessly in a peer-to-peer configuration without
the need for a LAN connection. A wireless access point connected to a 10/100 BaseT Ethernet network
with a SIP (Session Initiation Protocol) server is required for systems containing three or more VoIP WiFi
telephones (or a combination of WiFi and network cabled VoIP telephones). Conferences are limited by
the customer’s LAN media capabilities and the services available at each telephone.
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.
