Overview of the Cisco IP Phone
The Cisco IP Phone 7800 Series for Third-Party Call Control comprises a set of full-featured VoIP
(Voice-over-Internet Protocol) phones that provide voice communication over an IP network. They provide
all the features of traditional business phones, such as call forwarding, redialing, speed dialing, transferring
calls, and conference calling. The Cisco IP Phone 7800 Series is targeted for solutions that are centered on
Third-Party SIP-based IP PBX.
In this document, the terms Cisco IP Phone or phone mean Cisco IP Phone for Third-Party Call Control.Note

Physical and Operating Environment Specifications

Cable Specifications
•RJ-9 jack (4-conductor) for handset and headset connection.
The Cisco IP Phone 7811 does not contain a headset jack.Note
•RJ-45 jack for the LAN 10/100BaseT connection (on Cisco IP Phones 7811, 7821, and 7861) and the
LAN 1000BaseT connection (on the Cisco IP Phone 7841).
•RJ-45 jack for a second 10/100BaseT compliant connection (on Cisco IP Phones 7811, 7821, and 7861)
and the LAN 1000BaseT connection (on the Cisco IP Phone 7841).
•48-volt power connector.
Network and Computer Port Pinouts
Although both the network and computer (access) ports are used for network connectivity, they serve different
purposes and have different port pinouts:
•The network port is the 10/100 SW port; the Cisco IP Phone 7841 has a 10/100/1000 SW network port.
•The computer (access) port is the 10/100 PC port; the Cisco IP Phone 7841 has a 10/100/1000 PC
computer port.

Note
Phone Power Requirements
The Cisco IP Phone can be powered with external power or with Power over Ethernet (PoE). A separate power
supply provides external power. The switch can provide PoE through the phone Ethernet cable.
When you install a phone that is powered with external power, connect the power supply to the phone
and to a power outlet before you connect the Ethernet cable to the phone. When you remove a phone that
is powered with external power, disconnect the Ethernet cable from the phone before you disconnect the
power supply.
