Similar in function to Comrex's DH22 (which works on analog phone lines), VH2 provides users with the capabilities of a two-line digital hybrid, as well as the benefits of VoIP. With simple front-panel controls, VH2 enables users to manage telephone calls easily in excellent, studio-grade quality. Many broadcasters find VoIP trunks to be more cost effective and readily available than traditional phone lines. VH2 also connects directly to several VoIP PBXs.
