Internal Number
The Internal Number module enables extension-based dialing within your phone system. Think of it as creating shortcuts that let users call each other or reach specific features using simple extension numbers.
Setting It Up​

When configuring an Internal Number module, you'll need to provide:
-
Name: A descriptive name for the extension, such as:
- "Sales Conference Room"
- "Support Team"
- "Main Reception"
-
Number: The 1-4 digit extension that users will dial to reach this module. Pick it from the list of unused internal numbers you've added under Numbers > Internal Numbers.
-
Is a Private Number: This toggle belongs to a system-linking feature that is no longer available. Leave it off.
Extension numbers must be unique - you can't use the same extension number for multiple Internal Number modules. Manage your available extension numbers in the Internal Numbers tab of the Numbers menu.
Practical Example​
Here's a common way to use the Internal Number module:

In this example, an Internal Number module is connected to a conference room. Users with the phone system app or using a SIP account can dial the extension number to join the conference directly.
Internal Number modules are perfect for:
- Creating quick-dial extensions for team members
- Setting up easy access to conference rooms
- Providing short numbers for frequently used features
- Creating a simple internal directory system
- Showing as the internal caller ID when a user calls another extension (chosen in the user's contact method settings)
