Extensions

Extensions are part of phonegroups and serve as end points for calls, or where calls can be placed from. Extensions are set to use a Class of Service to define how calls from this extension are handled.

Adding an Extension

1) Enter the CLI's configuration mode.

2) Enter the number of the Extension you wish to create. You will be prompted with the minimum required settings. An extension does not necessarily need to be a number, but in most this cases this is recommended. 

4) Select a device type. (Tab after device_type to see available options)

5) By default the extension is created using your system defaults.  Use the show command to see the default values for the extension. 

6) A couple settings that may need to be changed first are Phonegroups and Class of Service (cos). Let's see what options we have for these.

7) Change the phonegroup.

8) Next change the Class of Service (cos)

9) Afterwards check to ensure the changes were saved.

Voicemail Setup

In order to setup voicemail this must be enabled manually on an extension. On most systems voicemail is disabled by default

1) Enter the CLI's configuration mode.

2) Select the extension to setup voicemail on.

3) Enable voicemail using the following command. 

4) Use the show command to show voicemail has been enabled. show

5) There are additional voicemail options, such as the option to set an email that voicemail can be forwarded to. 

6) Enable the voicemail to email feature, then set the appropriate email voicemail should be forwarded to. Then use the show command to ensure your setting were saved

It is important to remember that you use the correct email address. That being said it is NOT recommended to disable voicemail's saving to the extension itself to be sent only through email, in the event that there is something wrong outside of Intellasoft platform (transmission issues, email server (SMTP) issues)

7) Lastly it is important to set a PIN for the voicemail, so the user of the extension can access their voicemail securely and prevent unwanted access.
