IP Resources
This guide refers frequently to the term “IP resources,” which has an important meaning in
computer telephony (CT) jargon. In common English usage, the word “resources” refers to a
supply that can be drawn on when needed. Computing resources constitute the needed supply
to run CT applications, and different applications require different amounts of resources. The
supply of computing resources that is not actually in use is available to run applications.
A “resource” might be understood as an abstract way to describe the amount of computing
capability that voice processing software and hardware need to work together. Resources are
used to describe an interface of a physical device used for call processing, such as a phone, as
seen by a software application. Examples of such interfaces include a fax processing resource,
voice recognition resource, or text-to-speech resource.
The communication server installed—Inter-Tel CS-5200 or CS-5400—determines the amount
of IP resources the Inter-Tel 5000 can supply to support voice processing tasks.
Internet Protocol Resource Application
The Internet Protocol Resource Application (IPRA) supplies IP functionality for the system
and communicates to the IP phones, IP trunk gateways, and other IP endpoints across 10/
100Base-T Ethernet.
Inter-Tel 5000 IP Resource Usage
On the Inter-Tel 5000, IP resources are used to provide the following call processing capabili-
ties:
• IP endpoints
• IP network connections
• Faxing between Inter-Tel 5000 nodes
The correct allocation of IP resources is an important factor in maintaining a system that func-
tions without calls being blocked. System Administrators can promote nonblocking system
performance by making sure that the allocation of system IP resources is appropriate for their
needs. System Administrators having questions or concerns about the allocation of system IP
resources should contact their Inter-Tel equipment and service provider.
