The Cisco IP Conference Phone 7832
The phone has sensitive microphones with 360-degree coverage. This coverage lets users speak in a normal
voice and be heard clearly from up to 7 feet (2.1 m) away. The phone also features technology that resists
interference from mobile phones and other wireless devices, assuring delivery of clear communications without
distractions.
Like other devices, a Cisco IP Phone must be configured and managed. These phones encode and decode the
following codecs:
• G.711 a-law
• G.711 mu-law
• G.722
• G722.2 AMR-WB
Cisco IP Conference Phone 7832 Multiplatform Phones Administration Guide for Release 11.3(1) and Later
1
• G.729a/G.729ab
• G.726
• iLBC
• Opus
• iSAC
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.
Caution
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.
Finally, because the Cisco IP Phone is a network device, you can obtain detailed status information from it
directly. This information can assist you with troubleshooting any problems users might encounter when using
their IP phones. You can also obtain statistics about an active call or firmware versions on the phone.
