Cisco Unified IP Phone
The Cisco Unified SIP Phone 3905 provides voice communication over an Internet Protocol (IP) network.
The Cisco Unified IP Phone functions much like a digital business phone, allowing you to place and receive
phone calls. In addition, the Cisco Unified SIP Phone 3905 supports features such as mute, hold, transfer,
conference, call forward, and more.
A Cisco Unified IP Phone, like other network devices, must be configured and managed. These phones
encode G.711a, G.711µ, G.729a, and G.729ab, and decode G.711a, G.711µ, G.729, G.729a, and G.729ab.
Using a cell, mobile, or GSM phone, or two-way radio in close proximity to a Cisco Unified IP Phone
might cause interference. For more information, refer to the manufacturer
’
s documentation of the interfering
device.
