Go to for the latest 3300 variants

The March Networks 3300 Integrated Communications Platform (ICP) is the IP voice solution for businesses of 40 - 5000 users. The Mitel SX-2000 software provides the core functionality, feature content, networking, trunk access, and management capabilities of the 3300. The 3300 ICP is a direct evolution of the 3200 ICP but with new hardware and operating system. It integrates traditional telephony within an integrated voice and data architecture.

The first release, scheduled for September 2002, targeted customers in the 40 - 700 line size and will include basic WAN and desktop connectivity for IP telephones and consoles. The digital telephone connectivity is exclusively through IP-based Ethernet connection. The 3300 ICP can be a node in an SX-2000 network or cluster configuration and managed by OPS Manager.

Future releases will support the existing peripheral infrastructure of the SX-2000 and SX-2000 Light PBXs. We will focus on speech-enabled applications, Unified Messaging, Call Centres, Hot-desking, and Location independent working functions. The IP nature of the system has the potential for set mobility, IP clustering, Cluster resiliency, support for H.323 based devices and Teleworking.
