System Requirements and Limitations
The WiFi Telephones require a local 24–48 V 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. However, a wireless pick-up point connected to a 10/100 BaseT Ethernet with SIP server is
required for systems containing three or more WiFi Telephones (or a combination of WiFi and hardwire-
connected VoIP Telephones). Conferences are limited by the customer’s LAN media capabilities and the
services available at each end point.
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.
