Upgrading the Cisco ATA 186
Software
You can upgrade the program of your Cisco ATA 186 remotely. Upgrades can be
done by using either of two methods:
• executable file
• TFTP server
Note TFTP is case sensitive; if you use TFTP to upgrade your software, name your
files by using all lowercase letters.
Both methods require software available from cisco.com.
About Upgrading from Release 1.xx to Release 2.0
Caution Release 2.0 is not backward-compatible with Release 1.xx.
