17 IP Streaming, Programs, and TieLink
Tieline codecs support high quality IP audio streaming connections using the following protocols:
1. Tieline Session Data: Proprietary session data sent when Tieline codecs connect to each
other in order to establish, manage and terminate connections.
2. SIP (Session Initiation Protocol): EBU N/ACIP Tech 3326 compliant connections using SDP
(Session Description Protocol) when connecting to other brands of IP codecs.
3. Sessionless: The codec does not send session data when attempting to connect. Requires
the "send" audio port and "return" audio port to be configured.
Tieline Session Data
When a connection between two codecs is established:
1. The dialing codec sends session data including information about how the codec receiving
the call should be configured.
2. Once the answering codec receives session data it sends an acknowledgment to the dialing
codec and streaming can commence.
For example, if you configure a stereo program on the dialing codec using Opus encoding at
128kbps with specific jitter settings, this will be configured on the dialing codec when it connects.
SIP
SIP provides interoperability between different brands of codecs due to its standardized protocols for
connecting different devices. The codec is fully EBU N/ACIP Tech 3326 compliant for connecting to
any codec supporting SIP connections. For more information about SIP connections see
About SIP .
TieLink Traversal Server Network
TieLink is a secure, independently hosted global server network, with multiple global backups.
Linked to a TieServer domain, it centralizes Tieline codec contact list management and provides
self-discovery of codecs within customized ‘call-groups’. It also provides NAT traversal to simplify
connections. This service is free to all Tieline customers but is not supported with Bridge-IT or G3
codecs.
