Callback is a service that allows users to set-up long-distance calls via low cost VoIP technology. User first calls into a local telephone number that asks for access codes. The successful call will be captured by callback server and the call will be disconnected automatically. The server will then initiate a return call to user to ask for dialing destination number. The server will then connect the user to the destination number by a VoIP call.

 

Early VoIP Callback Service

 

JaJah is one of the first VoIP companies that’s getting a head start in taking advantage of the tremendous growth market provided by new data/internet mobile phone capabilities, and the high demand in certain countries for alternatives to poor local phone service (see search trends at the start of this report.) JaJah calls the service “web-activated telephony, and it uses VoIP technologies to connect from the Internet to land or mobile phones. While the service requires an Internet connection to establish the call, the communication takes place on a cell phone.

 

The process of VoIP callback starts with login on to JaJah website as a registered user. Just enter in your local phone number and the destination number of your recipient. JaJah service will establish the end-to-end call by first calling your phone first, and then your destination phone and you are no longer tied to the PC.

 

Advanced Callback Service

 

Another way around having to use the PC at all is if a mobile phone is Internet enabled. The JaJah site could be used to initiate the call straight from the mobile phone itself. In this approach, the mobile phone need to be installed with VoIP softphone which will pass the destination number to VoIP server directly for onward connection with the destination.
