In the coming months, we’ll be expanding our content delivery network around the globe, getting the connection up to light-speed even in remote areas. Now these servers will also be used for calls.

Unlike other apps, Telegram has a distributed infrastructure all over the world which we’ve already been using to deliver your texts faster than other apps.

If a peer-to-peer connection can't be established, Telegram will use the closest server to you to connect you with the person you’re calling in the fastest way possible. Whenever possible, your calls will go over a peer-to-peer connection, using the best audio codecs to save traffic while providing crystal-clear quality.
