IP Line Description, Installation and Maintenance
Note: 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 28 on
page 151.
Figure 28
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.
