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

call, placing a call on hold, transferring a call, and so on, are
performed from the Cisco
Unified IP Phone.
