Until now, we have been working with two extensions. The process to use a regular IP (SIP) phone is as follows: create the extension in the PBX, and then configure the device. However, if we have to configure a large number of extensions, and therefore devices, the process will be exhausting. The answer to this situation is to take advantage of the feature found in the PBX | Batch Configurations menu. In this menu, we have three options:
Endpoint Configurator
Batch of Endpoints
Batch of Extensions
This menu is for configuring a large number of extensions. It uses Comma Separated Values (CSV) which, when uploaded, will create, edit, or delete any number of extensions.
