What is the overhead?
  • This depends on a number of configuration factors but can be as low as 35kbps (similar to G.711 VoIP) or up to 60Kbps.
  • This overhead is for any number of channels between any two destinations, so as you add calls the overhead as a percentage becomes very small.
  • A 2.048Mbps E1, for example, typically has an overhead of just 8%.
