Unified communications platforms (UC), Interactive Voice Response (IVR), Session Initiation Protocol (SIP), Voice over IP (VoIP), on-premise or hosted solutions, virtualized services, the list goes on. A place for technicians, IT folks, and anybody with questions!

This is a place for anyone to discuss or ask questions about private switching, from the plastic on the desk, to the copper in the walls, to the PBX, to the telco providers themselves.
