1.1 Overview
The IP PBX Administration Guide provides instructions for administering the IP PBX system. IP PBX is
an embedded call-processing server communicating with client stations with Session Initiation Protocol
(SIP). It migrates the telephony network and the data network of a small-to-medium business (SMB)
company into a manageable converged network. IP PBX works with various IP phones (desktop, WiFi,
Bluetooth, and DECT), voice-over-IP (VoIP) gateways, and analog telephone adapters to route calls
among client phones, analog phones, and PSTN network. Additional voice features such as
conferencing, auto attendant, and voicemail are seamlessly enabled to all phones. IP PBX also
provides Internet access to all LAN devices through Network Address Translation (NAT).
IP PBX provides call control and media relay services to SIP clients and applications. It performs the
following primary functions:
․ Configurable multiple-layer IVR with office-hour setting
․ Fax relay and pass-through (T.38 and T.30)
․ Voicemail IVR system
․ Meet-me conference
․ SIP registrar
․ SIP outbound proxy for signaling and media
․ SIP gateway (FXO/FXS/ISDN BRI)
․ SIP PBX for extension calls
IP PBX has a built-in suite of voice applications for supplementary services, and no special-purpose
hardware is required. Therefore, the total cost of ownership of a converged network enabled by IP PBX
is lower than building separated infrastructures for legacy telephony network and data network.
Moreover, it comes with a web-browsable

interface to the data network configuration and voice
service provisioning, which brings both local and remote manageability of networks together to
facilitate administration.

It is highly recommended to use Internet Explorer 6.0 or later.
