BCM 4.0 Device Configuration Guide
Chapter 9
Telephony system and device programming
The following list provides links to the telephone and telephony system programming areas of the
system.
Within the context of the network, system telephones act as call end points or call initiation
devices.
• To make or receive calls, telephones must be set up with the correct line assignments.
• To make calls, users must know the correct destination codes and dial strings to reach other
internal or external devices.
Refer to the BCM 4.0 Networking Configuration Guide (N0060606) for connections to the
sections that describe line setup and numbering plans.
How telephones handle incoming and outgoing call traffic is determined by telephone features.
Some telephone features are set up for the entire system, while other parameters are configured on
a per-device basis.
System-wide telephony feature configuration
The system telephony settings must be set correctly to ensure that telephones can be
programmed correctly.

Telephone record configuration
When the system features are determined, the telephone DN records allow you to refine how
each telephone interacts with the system. DN record configuration can depend on what
features you want to allow users to access, or what features the type of telephone can support.
