IP-based intercom systems may be designed to handle purely VoIP traffic or, as in the case of the AlphaCom XE-series equipment, to handle both VoIP and traditional analogue intercom user stations. In the case of analogue stations, connectivity with the central exchange remains a necessity as above but IP-based outstations may be connected using bandwidth on an existing or on a separate LAN.
The STENTOFON Pulse offers High Definition voice quality, simple installation and ease of use. The IP-based system works by utilizing an existing IP network infrastructure. It employs open standards including SIP, HTTP and XML, making it simple to integrate and expand with third-party systems.
Most IP or VoIP stations are powered by the network cable using PoE (Power Over Ethernet), PoE is supplied from a network switch providing an PoE output. Sixnet PoE switches
