I will be using TURN servers. How much the TURN server cost for a 60-minutes call?
The mesibo charges only for the TURN bandwidth and not per-minute usage. The reason is that the TURN server is only active for a short duration, and hence it is not fair to charge for the entire call duration. Generally, the TURN server is active during the call initialization and then becomes inactive once the peer-to-peer connection is established. Hence, you will only be charged for bandwidth consumed during the active duration. The active duration can be longer if the participants are behind no-cooperative NATs/firewalls or can be a fraction of the total duration (say 30 seconds for a 60-minute call).
The bandwidth consumption depends upon the call quality and the active duration. Typically an HD (720p) call for 100 minutes will consume around 1 GB of bandwidth per participant. A non-HD call for 250 minutes consumes around 1GB per participant. Hence, depending on your call quality and TURN active duration, you can estimate the TURN bandwidth and the cost. You can use the mesibo console to monitor TURN usage and charges.
