No channel type registered for AudioSocket

Asterisk Asterisk Support
1

I’m trying to use AudioSockets in Asterisk 18.9.0, but Asterisk doesn’t seem to understand my AudioSocket endpoints.

  -- Executing [518@all-utilities:2] Dial("PJSIP/HostedTestTrunk-00000015", "AudioSocket/192.168.1.151:62021/1a332889-81bf-4903-be69-64cd54f51ca2") in new stack

    -- No devices or endpoints to dial (technology/resource)

AudioSocket doesn’t appear in my channel types:

Do I have all the necessary modules loaded?

Are there any .conf files I’m supposed to be using to enable this functionality?

It doesn’t exist as a channel driver in Asterisk.

Ok, but shouldn’t I be able to do:

Dial(AudioSocket/192.168.1.151:62021/1a332889-81bf-4903-be69-64cd54f51ca2)

from the dialplan? Why would I be getting:

No channel type registered for 'AudioSocket'?

Because you can’t dial it as a channel. It’s a dialplan application, like Dial is.

Ok, I figured it out. You can actually use an AudioSocket as a channel like this. You just have to load the chan_audiosocket.so module and it works.

Ah apparently I was on a different branch - yes, you are indeed correct. It is there if you load it.

Sorry for hijacking this thread.

Would you please mind explaining why one would
use Dial(AudioSocket/192…) over AudioSocket() ?

Thanks
