Telegram calls via Dante socks5 proxy server not working

  • 772

I've confugured Dante 1.4on Ubuntu 16.04 as a socks5 proxy for Telegram.

Chats are working, but voice calls are not, failing at "Connecting".

Is there something special I need to configure in order to proxy Telegram voice traffic?

I'm using a single non priveleged (>1024) TCP/UDP port + login + password for connection.

Thats piece of log while i am trying to call somebody:

Apr 15 23:05:38 (1523736338.510915) danted[22977]: info: pass(1): udp/udpassociate [: username%[email protected] 192.168.1.30.36562

Apr 15 23:08:33 (1523736513.020190) danted[22989]: info: pass(1): udp/udpassociate [: username%[email protected] 192.168.1.30.49065

I can answer the call at destination device but connection is looping and getting error after 30 seconds

Thanks!

  1. These settings solved my problem of calls

    Dante Server 1.4.2 (Ubuntu 16.04)

    /etc/sockd.conf

    logoutput: /var/log/socks.log

    internal: 192.168.1.14 port = 8912 external: 192.168.1.14 socksmethod: username user.privileged: root user.notprivileged: nobody client pass { from: 0.0.0.0/0 to: 0.0.0.0/0 log: error connect disconnect } client block { from: 0.0.0.0/0 to: 0.0.0.0/0 log: connect error } socks pass { from: 0.0.0.0/0 to: 0.0.0.0/0 command: bind connect udpassociate bindreply udpreply log: error connect disconnect } socks block { from: 0.0.0.0/0 to: 0.0.0.0/0 log: connect error }

    iptables -A INPUT -p udp -m multiport --dports 1024:65535 -j ACCEPT

    With these settings, you can already call from the telegram client desktop. In the telegram app In the proxy settings Disable the "Use for calls".

  2. Add to your pass/socks pass section with client-rule "command:" content: bindreply, udpassociate and udpreply

    https://www.inet.no/dante/doc/1.4.x/sockd.conf.5.html

    command The rule applies to the given commands. Valid commands are bind, bindreply, connect, udpassociate and udpreply. Can be used instead of, or to complement, protocol. The default is all commands valid for the protocols allowed by the rule.
