Extensions are used to provide a convenient method of diverting a call to a different location by selecting a short dialling code. Using these ensures that caller are unaware of the actual number that is being dialled. They simply enter an extension number and the extension divert service transfers the call. Extensions are intended to be used in switchboard services where calls are needed to be diverted to larger groups. In order to be implemented they must be part of an extension group and accessed through an extension divert service such as Group Divert.
An account can have as many extensions as required. An extension divert service, however, can only access those extensions within the extension group associated with the service. An extension can be part of many extension groups (so for example My Ext, x123 can be a part of my Work Ext group and My Home Ext group). When extensions are created they are allocated a default extension number. This can be changed via the edit screen but extensions within a group must have a unique extension number associated with them.
This is accessed by clicking Add new Extension in the main Extensions screen. You will be prompted for the name of the extension, which as usual should be unique and descriptive, and the telephone number the call should be diverted to. You first select the country in the drop-down box and then type the full telephone number as if you were dialling it from within that country into the following text box.
Each extension contains the following configurable parameters, accessed from the main Extensions screen by clicking the name of the extension.
Name - this is the name of the extension, which should be unique and descriptive.
Associated mail box - this is the mail box the call will be diverted to for voice mail.
Tel no - the telephone number the call should be diverted to. You first select the country in the drop-down box and then type the full telephone number as if you were dialling it from within that country into the following text box.
Extension number - this is the code the caller will use to transfer the call to the divert number when prompted. The code generated when the extension is created can be changed to another number but it has to be unique in your account.
CLI for extension - this is the number which the Callagenix server expects to be used to dial in to log in and log off the extension. By default it is set to be the same as the divert number. It is only significant if the 'Log-on required' option is selected, either in the extension or in the extension group.
Log-on required - if selected, this option allows the recipient of the diverted calls to signal that he or she is unable to take calls. This is done by calling a special Callagenix number and validated by checking the caller number against the 'CLI for extension' number.
Extension priority setting - this is used to determine the priority of extension numbers. It is only significant if the 'Priority in group' distribution setting is used in the extension group.
Go to ... when extension is busy, ... if no answer after ... seconds - this allows you to select if the caller will be sent back to the voice menu or put through to voice mail if the line is busy. Similarly it allows you to select if the caller will be sent back to the voice menu or put through to voice mail if the call is not answered witihin a specified number of seconds.
