Frequently Asked Questions
Q.
How can I recover the box if I forgot the password?
A.
There are two important passwords. One is the UIPassword, which protects access to the Cisco ATA
Web Server interface; the other is the EncryptKey, which protects access to the TFTP configuration file.
If you forget the value for the UIPassword but still have access to TFTP-stored configuration file, you
can modify the UIPassword via TFTP. However, if you are not configuring the Cisco ATA via TFTP, or
if you forget both passwords, the only way you can recover the box is to have physical access to the box
and do a factory reset on the box via the box voice configuration menu interface (Access Code:
FACTRESET#).
