4. Configuring the VoIP Router through IVR 
VoIP transmits voice data (packets) via the Internet, hence the condition and status of the network environment is 
relatively important to the telecommunications quality. If any one of the parties involved in VoIP communications 
has insufficient bandwidth or frequent packet loss, the telecommunication quality will be poor. Therefore, 
excellent telecommunication can only happen when the VoIP Routers are connected to the Internet and when the 
network environment is stable.     
 
Preparation 
1.  Connect the power supply, telephone set, telephone cable, and network cable properly. 
2.  If a static IP is provided, confirm the correct IP settings of the WAN Port (IP address, Subnet Mask, 
and Default gateway). Please contact your local Internet Service Provider (ISP) if you have any 
question. 
3.  If you are using ADSL (PPPoE) for your network connection, confirm the account number and 
password. 
4.  If you intend to operate the VoIP Router under NAT, the IP range of VoIP Router WAN Port and LAN 
Port IP Address should not be the same in order to avoid phone failures. 
 
Basic Setup 
The VoIP Router provides two setup modes:   
1.  Telephone IVR Configuration Mode 
2. Browser Configuration Mode 
IVR configuration provides basic query and setup functions, while browser configuration provides full setup 
functions. 
 
4-1 IVR (Interactive Voice Response) 
The VoIP Router provides convenient IVR functions. Users are able to get query and setup the VoIP Router 
with a phone-set and function-codes without turning on the PC. 
 
Note: When finishing the setup, make sure the new settings are saved. This will enable the new settings to 
take effect after the system is restarted. 
 
Instructions 
FXS Port: Connect to telephones. To access IVR mode, passwords should be entered, “* * password #”. 
Alphabets to digits conversion information is provided in the PPPoE Character Conversion Table. (Refer to 
Page 71) When correct IVR passwords are entered and accepted, an indication tone can be heard 
indicates the system is in IVR setup mode. Enter function codes to check or configure the VoIP Router. 
(Please refer to page 68 for function codes). 
Example: If your password is “1234”, enter 
* (star) * (star) 1 2 3 4 # (pound), and now you are entering IVR 
setup mode. Next, enter a function code to check or configure the VoIP Router. If your password is “admin”, 
enter 
* (star) * (star) * (star) 41 44 53 49 54 # (pound). Please refer to the IVR Functions Table (page 68) 
for available functions and codes.
