Logging Information for Troubleshooting
You can collect information relating to the operations of the Cisco Unified IP
Phone 7905G and 7912G and store this information in a log file on a server that
you specify. If you experience a problem with a phone, this information can be
useful for troubleshooting.
To collect information for troubleshooting, you will need the nprintf.exe tool.
This tool is bundled with the Cisco Unified IP Phone software. You can also
obtain this tool from the CCO website. It is included with the SIP Software
Package Zip file.
Changing the telephone
configuration
By default, the network configuration options are locked to
prevent users from making changes that could impact their
network connectivity. You must unlock the network
configuration options before you can configure them. See the
for details.
Phone resetting
The phone resets when it loses contact with the
Cisco Unified CallManager software. This lost connection can
be due to any network connectivity disruption, including cable
breaks, switch outages, and switch reboots.
LCD display issues
If the display appears to have rolling lines or a wavy pattern, it
might be interacting with certain types of older fluorescent
lights in the building. Moving the phone away from the lights,
or replacing the lights, should resolve the problem.
Dual-Tone Multi-Frequency (DTMF)
delay
When you are on a call that requires keypad input, if you press
the keys too quickly, some of them might not be recognized.
