TODO

• the app follows a mesh architecture for connecting the calls which is decent for 3-4 people but does not scale so well and puts extreme load on the users device for <4 people in a call, so implement SFU

• add screen sharing

note

coturn helps with NAT, and we are able to by pass most NATs and ISP's! even the super strict ones in India. if you find the call not working on any specific ISP or behind a very specific nat of FW feel free to drop a message
