37signals VoIP Mashup with Lypp contest

The 37signals VoIP Mashup with Lypp contest starts tomorrow at noon PST. Developers that accept the challenge and build a mashup application (or mashup an existing application) using both the Highrise API and the Lypp API can win some pretty cool prizes including a $3,000 Apple gift certificate, 20,000 minutes of Lypp call time, and a 12-month subscription for a Highrise MAX account for the Best App Champ (say that three times fast).

Accoring to Lypp’s Erik Lagerway, the key to winning is to make it useful, make it functional, and make it simple. Submissions will be accepted up until May 10th. Full details on the contest are available here.
