VICIdial Expert

India - Tests: 1 - Portfolio: 1

Hi, My name is Roy I install, configure, and administer open source auto dialers built upon the Vicidial platform. I have been installing and administering these VICIdial for years. I have a large number of clients, many of whom migrated from a hosted auto dialer, or were looking to move away from an older, expensive, proprietary auto dialer to VICIdial. Some clients use their Vicidial install to handle large volumes of inbound calls, and others use Vicidial for its powerful predictive outbound capabilities; most use Vicidial for blended inbound and outbound campaigns. No matter the case, Vicidial offers my clients compelling advantages over (much) more expensive proprietary auto dialers.
