If your employer allows it, you should be able to retrieve your messages. Here is how I suspect it would work:
- You call your office phone number (must be a direct line)
- A greeting message invites you to leave a message.
- At the beep that indicates the begining of the recording you key in your password .
- The answering system (if so programmed) recognizes the code number and sets off reading a few menu options, among which is one that allows you to retrieve your messages.
But these are just speculations, I have no idea if it is implemented in your enterprise phone system. Besides, you may have an extension number, not a direct line.
I suggest you call your number and explore the menu options the caller is offered. If you do not find any that allows you to retrieve messages, that option is probably not implemented.
Maybe you should investigate the possibility
the messages to your home phone. However I remind you that some employers may not like that: All that comes to the company is company property, and rerouting messages may be construed as espionage
If I were in your boots, I would not let my personal (private) messages (phone, e-mail) to transit through my employer's switchboard or e-mail server.
I would suggest that you ask the phone-system resource person.
