The UFTP firmware download is compatible with the NAT Traversal feature. If the
IP Phone is behind a Network Address Translation (NAT) device, then a different
public signaling port is used. The public signaling port is assigned dynamically.
See
Figure 24
Using NAT with UFTP
Two Download log files log the results of the UFTP firmware downloads:
"uftplog0.txt" and "uftplog1.txt". One file is active and one file is inactive.
When a file is full, it becomes the inactive file, and the other file is written to.
The active file displays the most recent entries.
On Voice Gateway Media Cards, the log files are located in the /C:/LOG
directory. The Download log files are limited to 10K each for a total of 20K.
Approximately 128 log messages can be saved in each log file.
On the Signaling Server, the log files are located in the /U/LOG directory.
The Download log files are limited to 400K each, for a total of 800K.
Approximately 5000 log messages can be saved in each log file.
The Download log files are generated during initialization of the UFTP
Server task. If the Download log files do not exist during the start-up of the
UFTP Server task, new Download log files are created.
