Installation: User and Extension Creation
2.5.3 Manually Creating Extensions
If the Auto-create Extn option is not enabled , you must manually create an extension entry for each phone being
installed. This can be done either as part of the process of manually creating users or it must be done separately using
the process below.
To manually create an extension:
1. Using IP Office Manager, retrieve the system's configuration.
2. To display the list of existing extensions, click Extension in the left-hand panel. Right-click on the right-hand
panel and select New.
a. In the Extn tab, set the following:
·
Extension ID
For a VoIP extension, enter any number so long as it is unique, i.e. not already used by another extension.
·
Base Extension
Enter the extension number to assign to the phone. Again, this must be unique. This value is used to
associate the extension with the user who has the same extension number.
·
Phone Password
This is the password used to register the phone with the system. If not set, the matching user's Login
Code is used.
b. To add the new extension, click OK.
3. Save the configuration changes back to the system.
To select the required codec:
If the Codec Selection is left set to System Default, the extension uses the system codec preferences . In most
cases this is preferred and any changes required should be made at the system level to ensure consistency for all IP
trunks and extensions.
However, if required, the Codec Selection of each individual trunk and extension can be adjusted to differ from the
system defaults.
1. Using IP Office Manager, retrieve the system's configuration.
2. To display the extension's settings, click Extension in the left-hand panel.
3. Select the VoIP tab.
4. Change the Codec Selection to Custom.
5. The Unused and Selected lists can be used to select which codecs the device uses and their order of
preference.
6. Save the configuration changes back to the system.
