The relaying and proxying of media through an intermediary system is useful for purposes such as NAT helping and network topology masking.


On the @voice platform, there are 3 settings:

  • Never
  • When Neccessary
  • Always


When Media Relay is set to 'Always', then your RTP will always be proxied through the @voice platform.


When Media Relay is set to 'When Necessary', RTP will only be proxied when it comes from a NAT network.


When Media Relay is set to 'Never', RTP will not be proxied via the @voice platform.
