Cisco Wireless IP Phone 8821 and 8821-EX Wireless LAN Deployment Guide
17
When using Coexistence (802.11b/g/n + Bluetooth), call capacity is reduced due to the utilization of CTS to protect the
802.11g/n and Bluetooth transmissions.
Multicast Audio
Multicast audio from Push To Talk (PTT), Music on Hold (MMOH) and other applications are not supported when
using Coexistence.
Voice Quality
Depending on the current data rate configuration, CTS may be sent to protect the Bluetooth transmissions when using
Coexistence.
In some environments, 6 Mbps may need to be enabled.
Note: It is recommended to use 802.11a/n/ac if using Bluetooth due to 802.11b/g/n and Bluetooth both utilizing 2.4 GHz, but
also due to the above limitations.
Languages

The corresponding locale package must be installed to enable support for that language. English is the default language on the
phone.
