The 2-line Cisco
IP Phone 7821 is an ideal choice for information workers and
teleworkers. It is well-suited for users who have light-to-moderate VoIP
communications needs. The 7821 has a 3.5-inch (8.9 cm) graphical,
grayscale, 396 x 162 pixel-based display and is backlit. It comes

co-located PC. The 2 programmable line/feature keys feature tricolour
LEDs that provide call status notification at a glance.
As options, a wall-mount kit is available for the 7821 for areas

is also available for customers who wish to change out the black that
comes standard with the endpoint. The 7821 comes with a 2-position
footstand.
