Set up Voice Mail
Press # key
You will hear the welcome message
It will ask you for your extension number- this is not your room extension - use your voicemail box number (which should begin with a 7 - in most cases it is the same voicemail box number which you have had)
When asked for a password, enter 1234#
And then follow the prompts to customize your password.
Once this is done, if you would like to set up a custom voice mail message, hit 7 and then follow the prompts.
