You can use the Avaya Connect Expansion Module application to extend the number of call feature buttons and line appearances for Avaya Vantage™ Connect. Your administrator can install the Expansion Module application either on the Avaya Vantage™ device where you have Avaya Vantage™ Connect as the active telephony application, or on another Avaya Vantage™ device. Only one Expansion Module application can run on the same Avaya Vantage™ device that has Avaya Vantage™ Connect.
