VoIP (Voice over Internet Protocol) 
VoIP enables telephone calls through existing Internet connection instead of going through the PSTN 
(Public Switched Telephone Network).  It is not only cost-effective, especially for a long distance 
telephone charges, but also toll-quality voice calls over the Internet. 
There are six items within the VoIP section: 
Wizard

 General Settings
,
 Phone Port, PSTN Dial Plan, 
VoIP Dial Plan 
and
