About

iSkoot was a mobile VoIP calling service that extended the reach of PC calling by allowing users to make and receive PC calls using only their regular cell phones, without needing special hardware or broadband connections. The company partnered with Skype to offer Skype-branded mobile software to mobile network operators in various countries, including Israel. iSkoot focused on mobilizing popular internet services like social networks, consumer email, and IM, and worked with device manufacturers and U.S. mobile operators to bring these services to mobile handsets while reducing data bandwidth usage and saving battery life. Its R&D center, which employed half the company's workforce, was located in Beit Shemesh, Israel. iSkoot's Kalaida™ Platform was designed to move data-intensive tasks through iSkoot-managed proxy servers, which transcoded and aggregated traffic to reduce data transmission and save battery life.
