Twilio is a useful tool for businesses to save money on core telephony activities by using its PBX, IVR, answering service, call routing, or other solutions at a fraction of the cost. The company recently ran a Netbook Contest category where developers were encouraged to explore the possibility of using Twilio for Fun & Games, and the winner was Simolio by Steve Castle, who won a netbook as a prize. Now, Twilio is challenging its developers to create applications that help people coordinate their plans, such as proposing meeting times or checking travel plans, with a deadline of midnight on July 5th. The company also offers resources for developers, including API reference documentation, SDKs, and industry reports, to help them build communications and digital engagement experiences.
