V.6.9

SIP (EBU TECH 3326 standard for audio over IP)

The European Broadcast Union (EBU) is promoting the interoperability of audio

codecs for any manufacturer. For this purpose the use and the application of a
subset of the Internet Protocols has been proposed. SIP/SAP/RTP and SDP are
the main protocols, although SIP is commonly used to refer to the whole

standard. This effort will allow to setup in a friendly way audio streaming
communications between several vendors of equipment.

The fist version of this standard was released in 2007 as EBU Tech 3326
standard.

The deployment of SIP Protocol Servers among the network will support calling

remote parties just by invoking their network name regardless of the actual
public or private IP addresses.

The physical location, often related to fixed IP addresses or subnets, is not
further meaningful. In this sense, specially portable audio codecs will profit with
an easy call procedure. Neither is required to agree ahead on the audio
compression type and data stream rate, because the SIP Protocol manages by

itself to negotiate the convenient communication details with the remote party.

For Prodys’ former customers performing a call using SIP is much the same as
using Prodys’ proprietary protocols given that the SIP configuration is set.

V.6.9.1.

Enabling SIP protocol for Prodys IP codecs

To enable SIP calls the codec administrator has to:

•

Provide an IP network.

•

Enable the IP network on the root NET menu.

•

Enable the Unicast / Multicast on the root NET menu.

•

Enable the SIP option at the Configuration >Streaming >Protocol menu.
