• What exactly are you expecting to do? Dante is a low latency audio protocol meant only for local nets, not for going over the internet. It has no facility for placing calls.

  If you install Dante Virtual Sound card (usually requires at least one real Dante hardware device on the network) or possibly Dante Via, Asterisk should be able to use it like it would be able to use any hardware sound card for things like redirecting audio output of a call, etc. I don’t know if Asterisk has support for multi-channel sound cards
  (beyond 2 channels), so you may be restricted to only two channels.

  I could see an application where you might want to redirect the output from a call to a Dante enabled mixer to enable the call to be heard over a PA system.

• Hi Jerry,

  I’m Dante Level 3 certified so I can help on the Dante side tho I’ve never done AES67 on Linux. So I think you can do this although I know you can’t do it purely in Dante (which I think you guessed based on the AES67
  reference) because you need Dante Virtual Soundcard and it is only available on Windows/Mac.

  You need to get Dante to create an AES67 stream that your Asterisk box can pickup with an appropriate driver. I’m assuming you have a Dante network up and running and you have the controller software connected to the Dante net and you at least know the basics. The hitch is that your source Dante device must support AES67 streaming. Audinate added support for that to their Brooklyn II cards in 2015 but that doesn’t mean your device is running a firmware rev that has support for it. Additionally, I believe OEMs can decide if they want to enable it or not. So before doing anything I would make sure your source supports AES67 streaming. You can open the device view for your source device in the Dante controller and if there is an AES67 Config tab you are good to go. If not, you will have to bounce the audio through another device that does support it (like a mixer) or get one of the Audinate AVIO output dongles and just plug it into a analog sound card in your Asterisk box.

  Assuming your source support AES67 streaming, in the device view on the Dante controller you’ll see an AES67 Config tab. You will probably have to enable it since I don’t think any OEMs turn it on by default. That will likely require the device to be rebooted when you make that change.
