Desk phone for two SIP lines

The Cisco CP-7821-3PCC-K9= is a corded VoIP handset that supports two simultaneous lines using the SIP protocol. It draws power from a PoE-enabled network port, so no separate mains adapter is required. The monochrome display and integrated speakerphone suit everyday office calls.

Check PoE and cabling before ordering

Your network switch or injector must supply Power over Ethernet on the RJ-45 port that will feed the phone. Two Ethernet sockets are provided on the base so the phone can sit inline between the wall jack and a PC. Verify that your call-control platform accepts the SIP, LDAP, CDP, SRTP, DHCP and TLS protocols listed in the specifications.

Fits a standard wall or desk mount

The unit measures 8.1 inches high, 8.1 inches wide and 1.1 inches deep, weighing approximately 1.91 lb. A black bezel and wall-mount hardware are included in the box. The second network port frees a switch port by passing connectivity through to a desktop computer. Licences supplied cover User Connect, Enhanced User Connect and Unified Communications Manager Express.

Questions about this item

Does the CP-7821-3PCC-K9= include a power supply or do I need to buy one separately?

The package contains the 7821 IP Phone and a black bezel. Power is supplied through the PoE RJ-45 port, so no separate power supply is included.

Which licence option should I choose for a small office using Unified Communications Manager Express?

The box includes a User Connect Licence, an Enhanced User Connect Licence and Unified Communications Manager Express entitlement, covering the three main deployment paths.

How does the 2-line capacity work when the phone is connected to a single PoE switch port?

The phone has two RJ-45 network ports; one connects to the PoE switch for power and data, while the second can pass the network to a PC, and the SIP stack handles two concurrent lines on that single uplink.
