Routing issue: Telegram audio/video calls fail to connect

[Vargock]

Hello! Could someone give me a hand? See, the government in my country has recently blocked audio and video calls in Telegram and WhatsApp. As a result of that, I tried configuring Throne to route these apps’ traffic through a server, but the calls still fail to connect, even when the person on the other end is using a VPN on his end.

My guess is that these messengers rely on specific protocols for calls, and I might not be routing them correctly. Other parts of the app work fine though.

Below are my settings, as well as the particular routing rule for Telegram. I've tried changing System Proxy to TUN Mode and changing servers. My Telegram app is also configured to use the system proxy, as shown in the screenshot. Could someone advise what adjustments might be needed to make it work?

Sadly Telegram does not support routing calls through proxies, so you either have to use Tun mode, or give up on calls for telegram.

Thanks for the link, will read it in a moment. Regarding "Tun Mode" — the thing is, I already tried using Tun Mode before posting here, but the calls still wouldn't connect.

It does work with Tun mode, but I suspect your routing profile has some issues. I suggest you change the rule for Telegram to just include the process_name item, The IPs of telegram's webRTC servers may not be fully in the geoIP/Site DBs, and the rule items are ANDed, so it may mess some stuff up. The safest way to handle telegram is by relying on its process name.
