Hi I installed Centovacast on my server. Unfortunately, the cost of traffic that my provider offers me is excessive. Do you have any advice? how can i calculate the traffic i am developing for each single radio?

Many services offer a verity of connection rates and depending on your cost you may want to look at a dedicated server which you can find for as little as $40 a month.

The other option is to limit the amount of time a listener can listen.
