FAQ:

1. What is a VOIP gateway?

     Making calls with your computer is called Voice over I.P., for "Voice over Internet Protocol". Or simply

      "VoIP" (pronounced "voyp"). It is also referred to as broadband phone, Internet phone service and digital

      voice. A VoIP Gateway is a network device that helps to convert voice and fax calls between an IP network 

      and Public Switched Telephone Network (PSTN) in real time.

 

2. What can VOIP gateway do for you?

     Imagine being able to use your computer to make phone( or video) calls with the help of special software

      and a microphone(& a camera)—and bypassing your phone company and their charges. Wouldn't that be

      cool? That is VOIP gateway's job.

 

3. Why choose Ejoin?

     Factory prices, better quality, better service, global delivery in 2 days, Ejoin is a good choice!
