TO SIP OR NOT TO SIP interview with Jacob Daniluck Jacob: Connecting over SIP should be straightforward if you use the designated encoding algorithms and other settings as mandated in the EBU N/ACIP Tech 3326 standard. However, it’s not always as straightforward as it may seem. Insider: Can you give us an example? Jacob: SIP does have it’s place from an interoperability perspective, but it also has it’s downside. Before using SIP over IP, it is useful to understand that SIP often requires both codecs to be configured with the same settings before connecting or the connection may fail. We’ve also found that not all professional codec manufacturers are fully compliant with all requirements for interoperability. Insider: So… it’s not as straightforward as it may seem? Jacob: Not always, however with a bit of knowledge, and perhaps some trial and error from timeto-time, we can get Tieline codecs connected to all the major codec manufacturers. Insider: Is there anything else we should know about SIP? Jacob: SIP does not support advanced software enhancements which deliver redundancy and rock-solid reliability over IP, for example, failover connections, redundant streaming, IP bonding, or error concealment strategies. Insider: So what does this mean for broadcasters? Jacob: It’s important to understand the limitations of SIP as well as the advantages. So, while SIP is important from an interoperability perspective, it lacks the ‘secret sauce’ you get when using two proprietary codecs from the same manufacturer. Codecs from the same manufacturer will generally connect more easily and offer redundant streaming, IP bonding, error concealment, and a host of other cool network configuration and monitoring features. 14 www.tieline.com
TO SIP OR NOT TO SIP interview with Jacob Daniluck Insider: I see… anything else we should know? Jacob: Tieline was the first non-European manufacturer to deploy the SIP standard and we were an active member of the ACIP group with our recommendation for packet size being implemented. Tieline was also the first codec manufacturer to deploy Opus encoding. Opus has grown in popularity because it is an open source codec capable of high performance at both high and low bit-rates. It is widely used in WebRTC applications and is one of the optional audio codecs mentioned in the EBU SIP standard. It has been implemented by several codec manufacturers and sounds great. Insider: What support do you normally offer customers who have questions about SIP? Jacob: On our website we have documents with useful information about setting up connections using SIP between Tieline and most of the major manufacturers, so this is a great place to start. These documents contain background information about the different ways you can connect over SIP. And if you can’t get connected after trying to configure SIP, you can always email or call our support team who will offer advice based on their vast experience in using SIP.
