Troubleshooting and Maintenance
Summary
Peer Firmware Sharing fails.
Cisco VT Advantage/Unified Video Advantage
(CVTA)
Phone call cannot be established
General Troubleshooting Information
Explanation
If the Peer Firmware Sharing fails, the phone will
default to using the TFTP server to download
firmware. Access the log messages stored on the
remote logging machine to help debug the Peer
Firmware Sharing feature.
Note These log messages are different from the
log messages sent to the phone log.
If you are having problems getting CVTA to work,
make sure that the PC Port is enabled, and that CDP
is enabled on the PC port.
See Network Configuration Menu
information.
The phone does not have a DHCP IP address, is
unable to register to Cisco Unified Communications
Manager, and shows a Configuring IP or Registering
message.
Verify the following:
1. The Ethernet cable is attached.
2. The Cisco CallManager service is running on the
Cisco Unified Communications Manager server.
3. Both phones are registered to the same Cisco
Unified Communications Manager.
4. Audio server debug and capture logs are enabled
for both phones. If needed, enable Java debug.
