This section describes the individual software components in a VCX
system.
A VCX system includes the following software services:
■
Call Processor — Performs call processing functions and generates
Call Detail Records (CDRs).
■
Authentication and Directory Service — Performs the following
tasks:
■
Authentication:
Authentication (for example, validating a username and password)
Authorization (for example, verifying a user is allowed to make an
international call)
User-specific routing or translation (for example, processes a
personal speed dial number)
■
Directory (routing and translation functions):
The routing function identifies, selects, and prioritizes all the
possible routes for a given call.
The translation function manipulates the access number as a call
propagates through the system.
■
Accounting Service — Sends, exports, and manages CDRs.
■
SIP Phone Downloader — Loads an application image on to a 3Com
phone, which enables SIP support on the phone.
■
Common Agent — Connects VCX software components such as the
Call Processor, Authentication and Directory Service, and so on, to the
Enterprise Management Suite (EMS) or other SNMP-based network
management tools.
■
Provisioning Service — Provides a web-based user interface for
managing authentication and directory data.
■
Call Records Service — Stores CDRs received from the Accounting
Service. Sometimes referred to as the Billing Server.
■
IP Messaging Service — Provides integrated voice messaging, fax,
and e-mail capabilities, and advanced messaging features such as Find
Me Follow Me call routing and text-to-speech e-mail reading.
