1.Demo Description
This chapter describes the basic features of the IP Media Server for HMP demo.
The IP Media Server for HMP demo is an object-oriented host-based application that demonstrates
using the Global Call API to build an IP media server, providing voice and fax services via IP
technology. The demo source code can be used as sample code for those who want to begin
developing an application from a working application.
Note: The IP Media Server for HMP demo is limited to a maximum of four simultaneous channels.
Additionally, the channel numbers used must be below 120; the demo will fail to run if you attempt
to use a channel number higher than 120.
The IP Media Server for HMP demo supports the following features:
• Voice service
• Fax service
• CSP barge in
• Configuration file
• Command line options
Note: The IP Media Server for HMP demo does not function as a gateway. Therefore, it can only answer
calls from the IP network. Gateway functionality can be added by writing additional software code
within the IP module that will allow it to make outgoing calls to the IP network, and connecting a
gateway to interface with the PSTN.
The IP Media Server for HMPIP Media Server (Global Call) demo is a cross-OS demo, designed to
run under both the Windows and Linux environments. Most of the differences in the environments
are handled directly by the programming interface and are transparent to the user. Other
differences, due to inherent differences in the operating systems, are handled by the Platform
Dependency Library (PDL). For more information about the PDL refer to the source code in the
pdl_win or pdl_linux directories directory.
