When you dial into your own voicemail box in order to check your messages, there is an option to place an outbound call that we call "voicemail callout".
See Voicemail System Options for a full list of all the administrative options available within the voicemail system as well as the keypresses to navigate to these options.
You would use this particular option by doing the following:
Voicemail callout is NOT enabled by default for any extension. The very simple reason for this is security. If someone knew your extension and voicemail pin code, they could make outbound calls using your extension!
Use a secure code
It's extremely important that you change your voicemail PIN code often and NEVER use an easy-to-guess code like 1234.
Change your PIN
Fonality recommends that you change your pin code after an employee leaves or if you think someone has gained access to it.
