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.
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.
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.
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.
