According to Twilio, all I see is information about STUN/TURN and how they charge money for using the TURN/relay server. However, it doesn't make sense to do P2P (wrt performance) for a multi-party conferencing.
So, i'm curious to know if Twilio uses some kind of a media server (for MCU/SFU) in between or does it do P2P connections.

The Twilio Video API is a room based API, users join rooms to connect to other users. There are two types of rooms though.
Peer to peer rooms use WebRTC's peer to peer nature to connect, and we don't recommend that you try to connect more than 4 users in this way.
Group rooms use a server-routed topology to support a larger number of Participants and features like Recording.
You can set the default room type in the Twilio console on the Video room settings page. You can also create rooms using the REST API and set the type at the time of creation.
Let me know if that helps.
