# Configuring Axia IP-Audio Driver to send channels in SIP Unicast AES67 format

## Scope

This document describes how to configure the Axia IP-Audio Driver for Windows to **send** its sources as AES67 SIP Unicast. We will not discuss multicast set up in this document.

> [!WARNING]
> You must be running version 2.10 or higher.

## Description

Version 2.10 and higher of the Axia IP-Audio Driver support sending stream as AES67 in either multicast or unicast format. Connections to the unicast sources by other devices are done using SIP.

## Configuration of the Sources

1. Launch the Axia IP-Audio Driver configuration. This can be found in Windows Control Panel.
2. Enable the Source by selecting the Enable checkbox.
3. Assign a friendly name. In this example, we've used PC 1.
4. Leave the Channel field blank.
5. Select Low Latency Stereo (AES67) as the Mode.
6. If you have a multi-channel version of the Driver, repeat this for each channel.
7. Click the Apply button to save and activate your changes.

> [!WARNING]
> You can configure some channels for unicast while others are set up as multicast. You can not configure a single channel as both.

This screenshot shows our properly configured sources. Sources 1 - 3 are configured as unicast. Source 4 is configured for multicast.

## Configuring receivers

Receivers request these unicast sources by the string sip:<channel>@<ipaddress>:<options>

In our example, the IP-Audio Driver is at IP Address 192.168.2.26, so our connection string in the receiver would be 'sip:1@192.168.2.26.' No options are required.

> [!WARNING]
> Other (non-Axia) devices may have different requirements for SIP unicast connections. The conventions mentioned here may not apply to other manufacturers' equipment.

Here is a properly configured xNode to receive the three unicast channels from the IP-Audio Driver.
