Cisco IP Phone 7821 — a two-line phone for Cisco Unified CM

CUCM2 linesPoE Class 1Wideband audio

The Cisco IP Phone 7821 is a two-line enterprise desk phone for Cisco Unified Communications Manager (CUCM 12.5 and later) and Cisco HCS. It has a 3.5-inch 396 x 162 backlit greyscale display, a wideband handset and speakerphone, an RJ9 headset port and a two-port 10/100 switch for a PC. It draws very little power on PoE Class 1.

Compatibility — check before buying:
This is the Enterprise (CUCM) version. It will not register to Webex Calling or generic SIP providers as shipped — for those, order the Multiplatform CP-7821-3PCC-K9=. On CUCM it needs a Basic User Connect Licence. Cisco lists the power adapter as a separate part (Cisco Power Adapter 3, UK version CP-PWR-ADPT-3-S-UK=): power the phone from a PoE switch (Class 1) or order the adapter. Tell us the phone system or provider you use and we check compatibility before you buy.

Best For

✓ Cisco Unified CM sites
✓ Common-area and back-office desks
✓ Low-power PoE deployments
✓ Users who need two lines
✓ Replacing older Cisco phones
✓ Cisco HCS customers

Singular Expert Insight
Check the code before ordering Cisco phones: without “3PCC” the phone is for CUCM. The 7841 adds four lines and Gigabit. Wired headsets are in our office & VoIP headsets and PoE switches in our PoE switches. Tell us the phone system or provider you use and we check compatibility before you buy.
