Generic Extension Initiation

In general terms, any generic extension is defined as a directory number assigned to a terminal of any type. A virtual generic extension is a directory number that has no terminal but the attribute virtual assigned. An EDN-only extension is a generic extension that has the attribute EDN assigned.

Generic extension initiation has mainly four steps:

• Define the directory number in the extension number series with the command number_initiate.

• Initiate the common service profile (CSP) with the command extension_profile.

• Define the configuration of the directory number depending on the user with the command extension.

• Assign the directory number to the terminal using a specific command (for example, ip_extension) or a service request.

However, not all the four previous steps are mandatory to generate a generic extension. Depending on which steps are done there are two different situations:

• Generic extension without terminal assigned, see Generic Extension Without Terminal Assigned.
• Generic extension with terminal assigned, see Generic Extension With Terminal Assigned.
