how can i customize conference service main greeting per account?

* to apply a media file

in monster-ui custom greeting only gives me the option for tts

btracht: I am not sure I understand your question. In any case, you can set TTS and open your browser developer tools, take note of the API it is sending the request to, then search for that API's schema and there you should be able to see the options available for that API.

anyone running open source 4.3 run into the duplicate channel_create webhook issue?

even with "restrict_channel_state_publisher": true,
