Because the Video-On-Demand doesn’t show what was done through extensions, correct?
Nevertheless, it would still be the most easy-to-setup, widely available solution for both, the streamers and viewers, I can think of.
I’m beginning to work on a similar project, where users can queue and the streamer allows for a short audio conversation to occur on a one-by-one basis. Similar to what happens on radio stations when calls are received. Prototype -RSC- Radio Show Call.
I will open a new thread to request for volunteers, but thought about writing here too since I found the concepts similar.
