I know this site will come across as just a little too technical, but I recall reviewing no similar resources before and that is why I am eager to have it featured on KillerStartups today. Plivo is basically a new telephony development framework. Using it, anybody will be able to build a telephony application from the ground up. That is, people who are technically-minded will. A Linux (CentOS or Debian) system is needed for Plivo to work as intended, and if you mean to try it know it will take you some time to have everything mastered. Yet, the rewards will be felt almost immediately as Plivo will let you come up with telephony applications of just any kind.
Simple click-to-call systems, voice-mail systems, IRVs… it is all creatable using Plivo. As a matter of fact, Plivo makes it possible to build fully-featured call center applications. It is just a matter of getting into the swing of things, and having the time to work things out.
Plivo can be used for free. Setup should not take you longer than 20 minutes, half an hour at most. And you will be guided all the way through.
