Lawo: IP Networking Guide For Video and Audio Applications
Lawo : Transporting audio and video streams over IP networks creates requirements beyond the well-known settings for e.g. office networks. This guide outlines general aspects of networking as well as the specifics needed for the correct transport of real-time audio and video data over standard IP networks. Even though the guide uses Lawo devices as examples for specific settings, these are also applicable for equipment from other brands.
This document covers setups for Lawo devices but the general principles can be applied to Clear-Com AOIP devices
