functions. With the base unit alone, the phone provides coverage for a 20 x 20 ft. (6.1 x 6.1 m) room and up
to 10 people.
Two wired expansion microphones are available for use with the phone. Placing the expansion microphones
away from the base unit provides greater coverage in larger conference rooms. With the base unit and wired
expansion microphones, the conference phone provides coverage for a 20 x 34 ft. (6.1 x 10 m) room and up
to 22 people.
The phone also supports an optional set of two wireless expansion microphones. With the base unit and
wireless expansion microphones, the conference phone provides coverage for a 20 x 40 ft. (6.1 x 12.2 m)
room and up to 26 people. To cover a 20 x 40 ft. room, we recommend that you place each microphone at a
maximum distance of 10 ft. from the base.
You can connect two base units to increase the coverage for a room. This configuration requires the optional
Daisy Chain kit and can support two expansion microphones (either wired or wireless, but not a mixed
combination). If you are using wired microphones with the Daisy Chain kit, the configuration provides coverage
for a room up to 20 x 50 feet (6.1 x 15.2 m) and up to 38 people. If you are using wireless microphones with
the Daisy Chain kit, the configuration provides coverage for a room up to 20 x 57 feet (6.1 x 17.4 m) and up
to 42 people.
The Cisco IP Conference Phone 8832NR (non-radio) version does not support Wi-Fi, wireless expansion
microphones, or Bluetooth.

Caution
Using a cell, mobile, or GSM phone, or two-way radio in close proximity to a Cisco IP Phone might cause
interference. For more information, see the manufacturer's documentation of the interfering device.
Cisco IP Phones provide traditional telephony functionality, such as call forwarding and transferring, redialing,
speed dialing, conference calling, and voice messaging system access. Cisco IP Phones also provide a variety
of other features.
As with other network devices, you must configure Cisco IP Phones to prepare them to access Cisco Unified
Communications Manager and the rest of the IP network. By using DHCP, you have fewer settings to configure
on a phone. If your network requires it, however, you can manually configure information such as: an IP
address, TFTP server, and subnet information.
