Cisco Small Business ATA Administration Guide
Q. How do I access the ATA device if I forget my password?
A. By default, the User and Admin accounts have no password. If the ITSP set the
password for either account and you do not know what it is, you need to
contact the ITSP. If the password for the user account was configured after you
received the ATA device, you can reset the device to the user factory default,
which preserves any provisioning completed by the ITSP. If the Admin account
needs to be reset, you have to perform a full factory reset, which also erases
any provisioning.
To reset the ATA device to the factory defaults, perform the following steps:
1. Connect an analog phone to the ATA device and access the IVR by pressing the
asterisk key four times: ****
Press the appropriate code to reset the unit:
• Press 877778# to reset the unit to the defaults as it shipped from the ITSP.
This will reset the User account password to the default of blank.
• Press 73738# to perform a full reset of unit to the factory default settings.
The Admin account password will be reset to the default of blank.
2. Press 1 to confirm the operation.
Press * to cancel the operation.
3. Log in to the unit using the User or Admin account without a password and
reconfigure the unit as necessary.
Q. My ATA device is behind a NAT device or firewall and I'm unable to make a
call or I'm only receiving a one-way connection. What should I do?
A. Complete the following steps.
1. Configure your router to port forward "TCP port 80" to the IP address currently
being used by your ATA device. If you do this often, we suggest that you use
static IP address for the ATA device, instead of DHCP. (For help with port
forwarding, consult your router documentation)
2. On the Line tab of the administration web server, change the value of
Mapping Enable
to yes. On the SIP tab; change
EXT IP
the parameter to the IP address of your router.
3. Make sure you are not blocking the UDP PORT 5060,5061 and port for UDP
packets in the range of 16384-16482. Also, disable "SPI" if this feature is
provided by your firewall. Identify the SIP server to which the ATA device is
registering, if it supports NAT, using the
Substitute VIA Addr
Outbound Proxy
parameter.
