Fonality trixbox Pro

Fonality's trixbox Pro, the business version of its IP-PBX software trixbox, comes in four editions: Pro Standard Edition (SE), Enteprise Edition (EE), Call Center Edition (CCE) and Unified Agent Edition (UAE). Fonality uses what it calls a hybrid-hosted architecture: a split, hosted-plus-premise model that includes free VoIP calling and monitoring like most hosted solutions provide, but also PSTN connectivity and call privacy like you'd find in a more traditional PSTN set-up. Started by enterpreneur Chris Lyman about five years ago, Fonality first came to many solution providers' notice with its Asterisk-based PBXtra.
