The CUPC client is a feature-rich client that offers a lot of productivity enhancements to the end user. It is flexible for both the stationary and mobile workspace users with deskphone CTI control and softphone. The collaboration features provided by the client cover Instant Messaging, audio/video calls, web conferencing—all at the click of a button. The idea of escalating a conversation as needed gives the end user the ability to get more done in a single interaction than has ever been provided before. The click-to-action functionality of CUPC gives the power of advanced collaboration features to end users with little to no knowledge of how to initiate them. This is especially evident with video and web conferencing because these two collaborative mediums have historically had low adoption rates because of complex scheduling and setup.
