The activation procedure for a SIP phone depends on the type of phone being used. Contact your Service Provider or review the appropriate document for details.
Administration for a phone system with SIP phones must include creation of an Auto Attendant that includes a menu item configured for voicemail retrieval because the message button on other phones is not integrated with the phone system. See Configure Auto Attendant Menu Options and Example: Create a Custom Auto Attendant for Voicemail Access for details.
