Product Overview

Comrex Switchboard is a feature that allows users to bypass common IP networking snags (like private LANs and firewalls) by routing data through a private server maintained by Comrex.  Switchboard within the hardware codec enables the following functions:

  • Comrex audio codecs can sync with a cloud based server and deliver status information
  • Comrex audio codecs can determine their public IP address and the type of any NAT-style router ahead of the codec, and display that information to the user
  • Comrex audio codecs can display presence, status, NAT info and IP addresses of other codecs within the same fleet
  • Comrex audio codecs can share this information with codecs outside the fleet (Shares)
  • Comrex audio codecs can take instruction from the server on how best to traverse NATs when placing a call between two codecs

Features

  • Routes data through private, Comrex owned server
  • Easy way to bypass IT snags (like private networks and firewalls)
  • Free to use
  • Included with ACCESS & Liveshot; available for purchase for BRIC-Link II

Without getting bogged down in too much technical detail: Switchboard TS is designed to allow your BRIC codecs (such as ACCESS) to connect with each other without having to have an IT guy onsite everywhere you go.

This diagram shows a typical NAT Router scenario: a codec connecting to Switchboard TS “punches a hole” through the NAT or firewall which in turn allows for a return path back to the codec. Once a codec has reached out to another device on the Switchboard TS, the two units handshake and exchange all of the “technical details” that they need to send audio back and forth.

These “details” include the specific route that data needs to travel to get to each device. This is really the tricky part since NATs and firewalls can make it difficult for data to get through. However, once the two devices have made contact via the Switchboard TS, a “Peer-to-Peer” connection is established and audio is bidirectionally transmitted until either one of the units disconnects or the circuit is terminated.
