You are describing using WebRTC with a one-to-many requirement. WebRTC is designed for peer-to-peer streaming, however there are configurations that will let you benefit from the low latency of WebRTC while delivering video to many viewers.

The trick is to not tax the streaming client with every viewer and, like you mentioned, have a "relay" media server. You can build this yourself but honestly the best solution is often to use something like Wowza's WebRTC Streaming product.

To stream efficiently from a phone you can use Wowza's GoCoder SDK but in my experience a more advanced SDK like StreamGears works best.
