If TieLink Does Not Connect:

  1. Ensure TieLink and at least one relevant interface is enabled and ‘stunned’ on both codecs; i.e. the STUN Status for the interface is Connected.
  2. Check STUN server settings.

If a TieLink Fuse-IP Connection Does Not Connect:

  1. Ensure Fuse-IP is enabled in the TieLink panel in Toolbox, or in the codec’s TieLink Settings screen, for both the dialing and answering codecs
  2. Check at least one interface has been added to the Fuse-IP configuration in the TieLink panel in Toolbox, or in the codec’s TieLink Settings screen, for both the dialing and answering codecs
  3. Verify that the STUN Status for at least one interface in the Fuse-IP configuration is Connected on both the answering and dialing codecs.
  4. Check that the answering codec is not already connected using TieLink Fuse-IP. Only one Fuse-IP connection is currently supported.

If SmartStream PLUS Connections do not connect:

  1. Based on the priority order of interfaces in the TieLink panel, a SmartStream PLUS connection may automatically use TieLink Fuse-IP as one of the connections if Fuse-IP is enabled at the dialing or answering codec. If TieLink Fuse-IP is chosen, then that connection will only succeed if the Fuse-IP stream is available at both ends. Disable Fuse-IP as an interface in TieLink to avoid Fuse-IP being selected in this scenario.
  2. When “Discrete once only” or “Discrete recurring” is selected, with TieLink Fuse-IP enabled, TieLink Fuse-IP may be selected to transmit one of the streams. In this situation, if the answering codec is already connected to another codec using TieLink Fuse-IP, then the connection will fail for this stream because only one Fuse-IP connection is supported using TieLink.
  3. When “First Available” is selected, TieLink Fuse-IP may be used if it is the first interface “ready” in the TieLink panel interface list. In this situation, the connection will fail if the answering codec is already connected to another codec using TieLink Fuse-IP.

Configuration Restrictions for TieLink

TieLink only supports one SmartStream PLUS redundant streaming connection on each audio stream. TieLink also does not support uncompressed PCM connections, or encoding using aptX Enhanced, G.711 or G.722.
