Both the Sipura and the Linksys ATAs have built in an IVR (Interactive Voice Response) into their firmware. You can access this IVR by using a connected phone and pressing **** (the star button 4 times). You should then be greeted by the voice response asking you to place a command followed by the # (pound) sign. A list of these commands are as follows:


100 - DHCP Client status (whether or not the unit obtains its IP address by DHCP).

110 - Announces the current IP address of the device.

101 - Change DHCP client. (1 to enable, 0 to disable)

111 - Assign the ATA a static IP address. To assign a static IP address, replace the dots in the IP address with the star key and then terminate with the pound key. (DHCP must be disabled, otherwise you will hear Invalid Option.)

120 - Announces the subnet mask.

121 - Used to set the subnet mask. (Use the same format as with 111 command.)

130 - Announces the default route (gateway).

131 - Sets the default gateway. (Use the same format as with 111 command.)

140 - Announces the MAC address of the adapter.
160 - Announces current setting of primary DNS Server.
150 - Announces the firmware version.

732668 - Reboots the ATA, resets all configurations back to default. Requires password.
