FreeKall : an offline voice calling service
Three Bangalore based engineering students, Yashas C Shekar, Vijaykumar Umaluti and Sandesh E, have launched FreeKall, a free voice calling service for those who do not have any internet access.
FreeKall makes money by making people listen to advertisements during calls. So once two users are connected, they will be able to hear 10 second advertisements after every two minutes in the middle of the call. Freekall has tied up with a media agency called Streetsmart Media Solutions for the advertisements.
To make a FreeKall users have to dial the numbers 080-67683693 and the call will be disconnected after a ring. After that, the automated system calls the user back and asks them to dial the desired number and get connected. The system can currently support 20,000 calls per second. FreeKall is currently in Beta as of now and so far it has already been used to make nearly four lakh (400,000) calls so far.
Registered users can make 12 minute calls in 24 hours and un-registered users can make calls for upto three minutes. Once the service goes live, registered users will be able to make unlimited calls.
The company is aiming for nearly 10 million calls a day after getting the necessary legal clearances and expects revenue of nearly $30 million at the end of the next fiscal year.
"The response has been phenomenal. Our servers crashed about seven times and we had to bring it back up," said Yashas Shekar, the 23-year-old who co-founded the company with college-mates Vijayakumar Umaluti and Sandesh Eshwarappa. "On the flip side Sandesh, and Vijayakumar have not slept since Saturday," chuckled Shekar.
