VoIP Telephones & Voicemail

Avaya Phone Deployment

SSU IT has moved to a new VoIP phone service provider and is upgrading the campus telephones in an effort to unify and improve phone service throughout the university.  As of February 24, 2017, all Cisco VoIP phones have been upgraded to Avaya VoIP phones. We will begin the process of converting existing Nortel phone users to the new platform in the coming months. This website will continue to be updated as the project moves forward. Contact the IT Help Desk for additional information.


Visit the Avaya VoIP Telephone Features and User Guide website for additional information on how to use the Avaya VoIP phones.
