An extension in the context of a PBX (Private Branch Exchange) system refers to a designated line or number within the phone system that allows users to make and receive calls internally and externally. Essentially, an extension is a unique identifier associated with a specific user or device within the PBX system.

Creating Extensions

To generate an extension, navigate to NextGenSwitch > Extensions > Extensions, where you’ll find the most crucial fields for configuration.

Name: The essential information to include is the name of the user associated with this extension.

Code: It is crucial to provide the extension number for identification and communication purposes.

SIP Information: Please ensure to specify the IP address for our NextGentSwitch, as it’s vital for network connectivity and management.

Username, this is the User Device.
Password, the password created on the extension’s device.

Call Limit: Please configure the call limit, which determines the maximum number of simultaneous calls that can be received.

Call Forwarding option: The call forwarding option allows you to redirect incoming calls to another number when certain conditions are met, such as when the line is busy, unanswered, or immediately upon receipt.
