For those who do not mind the annoyance of advertisements right in the middle of a conversation, a team of engineers in Bangalore has a free voice calling service for any part of the world. Termed FreeKall, it brings voice-over-internet-like services to those without internet access.
To make a FreeKall a user dials number 080-67683693 and the call is disconnected after just one ring. Following this, the system calls back the user, and an automated system prompts the user to dial the desired number.
For now, unregistered users can make calls that last three minutes. For those who register, the conversations can last 12 minutes. In about a month, there will be no limit on the amount of time a person can FreeKall. International calls will be possible in about a month, once legal clearances are obtained.
FreeKall makes money by making people listen to advertisements. So, when the call is connected, the user hears an advertisement instead of a ringing tone. And at intervals of two minutes, the caller and the called party will have to pause the conversation and hear an advertisement for soaps, shampoos and the like.
Note: when you get a call back and asked to dial the destination number, please enter only 10 digits number without 0 followed by HASH and your call will be connected. The receiver will get you number displayed at the CLI.
