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#).
Q.
What is the maximum distance from which I can drive an analog device with a Cisco ATA?
A.
Table 8-6 provides maximum distances for this question.
Table 8-6 Ring Loads and Distances
The Cisco ATA, however, is not designed for long distance. The simple test is to determine if the phone
or phones that are connected to the Cisco ATA work properly in their environment.
Pay attention to the following questions:
1. Can the Cisco ATA detect on/off hook from the analog phone?
2. Can the Cisco ATA detect the DTMF signal?
3. Can you dial the remote side?
4. Can the Cisco ATA ring the phone?
5. Is voice quality satisfactory?
