To modify an existing user's configuration details
Access the User and Device Configuration form.
Select a user by clicking the appropriate row in the User and Device Configuration list.
Click Change. A detailed User and Device Configuration dialog appears.
Modify the necessary field(s) in the User and Device Configuration dialog.
Notes:
The Directory Number (DN) and Device Type field are required fields.
Changing the user's DN automatically deletes the user's existing voice mailbox and creates a new voice mailbox that is associated with the new DN.
You can change a phone's device type only within the category of devices to which it belongs. That is, you can change a Multiline IP device to a different Multiline IP device (for example, 5010 IP to 5235 IP), but you cannot change a Multiline IP device to an analog or DNI device type (not 5010 IP to Analog).
Click Save.
