How do I change my voicemail greeting over the phone?

Voicemail greetings can be accessed and managed by dialing *97, then taking the following steps:

The default voicemail password is 1234

Select Advanced Options #5
1. To record a greeting Press 1
  - Choose a greeting between 1 and 9 (this is the greeting you want to record)
2. Choose a greeting (this option lets you choose your default greeting. The default greeting is what plays if an extension dials you directly or if a call is transferred to your voicemail)
