Call coverage is a critical capability for executive administrators and others who monitor and manage the various status of calls. For high call volume positions, the Cisco Unified IP Phone Expansion Module 7915 and the Cisco Unified IP Phone Expansion Module 7916 deliver an adjunct solution to instantly determine the status of a number of lines beyond the number supported natively in the wideband audio Cisco Unified IP Phones 7962G, 7965G and Phone 7975G. The Cisco Unified IP Phone Expansion Modules extend the call coverage capabilities with additional buttons and an LCD display.
