Table 8-3 General Cisco IP Communicator troubleshooting
Symptom Explanation and solution
Poor quality when
calling digital cell
phones using the
G.729 codec
When the user chooses to use low-bandwidth (the G.729 codec), calls between
Cisco IP Communicator and a digital cellular phone might have poor voice
quality. Use G.729 only when absolutely necessary.
Resetting
unexpectedly
Cisco IP Communicator resets when it loses contact with the
Cisco CallManager server. This lost connection can be due to any network
connectivity disruption, including cable breaks, switch outages, and switch
reboots. A lost connection can also be due to roaming out of range while using
a wireless network connection.
Or, another system administrator with access to Cisco CallManager might have
intentionally reset devices.
Dual-Tone
Multi-Frequency
(DTMF) delay
If you enter digits too quickly, some of them might not be recognized.
