The document discusses the features and capabilities of the Alphacom E VOIP system from Zenitel. Key points include: - VoIP can be implemented over LAN or WAN without additional hardware between exchanges or from the head end to IP stations. Only CAT5 connections are needed. - The system is backwards compatible by replacing the AMC board with a new AMC VoIP board, retaining all existing features. - A variety of IP station options are available that do not require additional hardware or external boxes, and include power-over-Ethernet capability. - Virtual master and SIP interoperability allow the system to connect to other VoIP and SIP products. IP stations do not require subscriber boards
