1.1 Introduction
H3C XE 200/2000 IP PBX (hereinafter referred to as XE IP PBX) is a part of H3C’s
integrated cross-industry VoIP solution designed for enterprise users. It can integrate a
large number of voice devices into a voice network that is easy to maintain, manage
and upgrade. With the XE IP PBX, you can make full use of the functions available with
the voice gateways and IP telephone terminals and even obtain function enhancement.
Thus, your investment can be protected to the maximum extent.
As a VoIP server, the XE IP PBX can centralize management of devices such as voice
gateways and IP telephone terminals and uniformly process VoIP services. The major
functions that it provides include registration management, dialing routing management,
call control, and service processing:
1) Registration management: When receiving a register request from a voice
gateway or terminal, the XE IP PBX accepts or rejects the request according to the
registration management policy and records the dynamic information such as the
online state of the gateway or terminal as well.
2) Dialing routing management: The XE IP PBX maintains the number information of
voice gateways and terminals and a mapping table from number to IP address and
port. When a voice gateway or terminal receives a dialed number, it sends a call
request to the XE IP PBX. Then the XE IP PBX searches for the number mapping
table to find the IP address and port number mapped to the dialed number.
3) Call control: The XE IP PBX supports call tracing, statistics in addition to call
connection, maintenance, and release. The XE IP PBX provides two approaches:
redirection and routing.
4) Service processing: Besides the basic call services, the XE IP PBX provides the
traditional PBX service. Service information can be set by administrators or users
through the GUI client or a terminal.
