  • Overview
  • Integration of Telephony

    Your endless wiring nightmares as configuring new extensions in the legacy PBX system are going to end. Just plugging/unplugging for the configuration! This is what VigorIPPBX 2820 embedded browser-based admin-function can do for multiple IP-based phones located under different LAN. The simplicity is opposed to costly services charged by legacy PBX vendors.
