Introduction
The Inter-Tel 5000 platform can be licensed and programmed to support multi-protocol, IP,
SIP, digital, and single line endpoints, softphone applications, as well as other endpoints and
performance-enhancing hardware. The platform supports desktop and mobile endpoints that
operate inside the local area network (LAN) or can be moved to the public network—the Inter-
net—without reprogramming the system or jeopardizing network security.
Types of hardware supported include basic “hard” IP endpoints used by workers in business
office environments. Some endpoints are multi-protocol—that is, they operate in either IP or
SIP mode. Some operate in IP mode only and others operate in SIP mode only. Other end-
points supported include wireless IP endpoints, the Inter-Tel Model 8602 IP softphone applica-
tion, and the Model 8601 SoftPhone for Pocket PC, which operates in SIP mode only on a
Personal Digital Assistant (PDA). Single-Line Adapter endpoints support standard single line
endpoints.
For attendant capability, the system supports a 16-extension direct station select (Mini-DSS)
unit or 50-button or 60-button DSS/Busy Lamp Field (BLF) Units. The Mini-DSS attaches to
one of the Inter-Tel six-line display IP or digital endpoints, and the DSS/BLF Units attach to
digital display endpoints. To enable IP communication through the public telephone network,
the Inter-Tel 5000 platform also supports gateway trunk hardware.
To install and configure IP and SIP endpoints requires knowledge of appropriate network set-
tings and familiarity with the associated hardware and software. Installation and configuration
information for all IP and SIP endpoints should be referred to an Inter-Tel-certified service
technician. For further information, contact your authorized Inter-Tel equipment provider.
For additional information, see “System Configurations” on page 12.
Base Server IP and SIP Emergency Calls From a Remote Site
To locate and quickly respond to a caller needing help, emergency response services depend on
accurate information from Caller ID or, in Europe, Calling Line ID (CLID) features. Because
of this reliance on Caller ID and CLID data, emergency responders can be misdirected or
delayed if the Caller ID or CLID information provided to a dispatcher is incorrect.
To help ensure that emergency services can respond quickly to IP or SIP endpoint calls from
remote sites, the remote site should be equipped with a correctly configured MGCP or SIP
gateway. If a designated Emergency Call number is dialed from a remote site equipped with a
correctly configured gateway, responders can be dispatched to the site of the emergency. How-
ever, if the remote site is not equipped with a correctly configured gateway, the call will be
identified, instead, as coming from the location where the system Base Server is located.
NOTE
For an explanation of what is meant by “endpoint,” see “Endpoints and Phones” on
page 2.
NOTICE
Emergency Call phone numbers include:
• 911, the default for U.S. systems.
• 999, the default for UK systems.
• If applicable, 112, an emergency number used widely in Europe outside of the
UK.
Any emergency dial number sequence that is appropriate for the location. Ask your Inter-
Tel equipment and service provider or certified technician for details.
