Troubleshooting and Maintenance
Explanation
If the peer to peer image distribution 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 to peer
image distribution feature.
Note
These log messages are different than 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.
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.
