4Using the Cisco Unified IP Phone Expansion Module 7915

The Expansion Module 7915 functions as a line appearance or programmable button module, allowing you to keep track of calls in progress, calls on hold, and calls requiring transfer, or to access phone services. Most call functions, such as answering a call, placing a call on hold, transferring a call, and so on, are performed from the Cisco Unified IP Phone.
