When an audio stream is Offline it is unavailable within the TieLink Traversal Server Network. Possible reasons an audio stream may be offline include:

  1. The codec is offline.
  2. An audio stream is not advertised on TieLink.
  3. TieLink and/or TieLink interfaces are disabled in the codec.
    Ports are not open.
  4. The Contact List panel in the Toolbox Web-GUI may need ‘refreshing’.
    DNS – Not resolving the STUN server set in the TieLink panel. Note: If a codec has a statically configured IP address, ensure that DNS Server settings are also configured.
  5. DNS – Not resolving https://tieserver.com
  6. The codec firmware version is not compatible.
