Voxbone, a Los Angeles-based VoIP origination services company, recently had a contest for applications that used its VoxAPI, which gave the developers access to features including ordering DID numbers. The winners of the contest were Voztelecom’s Oigaa (go to www.oigaa.com); X Machine’s IVR Factory, a Web-based IVR content management system, deployment and hosting platform ( go to www.ivrfactory.com); and Communicatii Libere’s DTL R manager, an open-source Asterisk-based PBX solution (go to www.hostedvpnswitch.com.)
