required to help you with problems. To obtain assistance from 3Com
Customer Service, either reboot to a previous version of the system
software or install a license for R4.2.
Third-Party Drivers
You can add and configure third-party telephones for use on a system.
The third-party vendor supplies the interface hardware and a software
package to support the telephones.
The process of adding third-party telephones includes these steps:
■
Install the device type license — Each third-party device type
(typically a telephone) must be licensed for use on the system. The
license governs the type of device and the number of devices of that
type that can be added to the system.
■
Installing the software driver — This step places the third-party
driver software on the system disk.
■
Importing the software driver — This step activates the third-party
driver software.
See the online Help for more information about these procedures.
To remove a third-party driver, you must either purge the system
database, or revert to a previous database in which the third-party driver
was not installed.
Software Upgrades When you upgrade the system software, you do not need to reinstall and
import the third-party drivers, provided that you continue to use the same
system database after the upgrade.
If you upgrade the system software and choose to start with a new
database, or if you revert to a database that did not include the
third-party driver, import the third-party driver again.
Third-Party
Telephone Groups
When you install and import a third-party driver, the system creates a new
telephone group for the third-party telephone type. When you add
third-party telephones to the system, by default the system adds them to
this group.
You cannot delete the default third-party telephone group.
