Understanding the Cisco Unified IP Phone 7902G
The Cisco Unified IP Phone 7902G is an entry-level IP Phone that addresses the
voice communication needs of areas such as lobbies, hallways, and break rooms
where only minimal features are required. This single-line phone supports a
maximum of two calls and one directory number, and inline power for receiving
power through and Ethernet connection. This phone also supports features that
you have come to expect from a basic telephone—such as call hold, call waiting,
call forward, call transfer, redial, and conference calling.
