System Requirements and Limitations
VoIP
Two VoIP telephones can be connected in a peer-to-peer configuration without the need for a LAN.
Systems containing three or more VoIP telephones require a 10/100 BaseT Ethernet network with SIP
(Session Initiation Protocol) server. Call capacity is limited by the customer’s LAN media capabilities
and the services available at each end point.
VoIP WiFi
Two telephones can communicate wirelessly in a peer-to-peer configuration without the need for a LAN
connection. Systems containing three or more WiFi telephones (or a combination of WiFi and hardwired-
connected VoIP telephones) require a wireless access point connected to a 10/100 BaseT Ethernet
network with SIP server. Call capacity is limited by the customer’s LAN media capabilities and the
services available at each end point.
Multicast Broadcasting
Each telephone receives multicast audio streams and broadcasts the audio received. Multicast paging
achieves public address functionality when multiple endpoint amplifiers broadcast an audio stream
received from a multicast socket. 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.
