+Subject: [PATCH] Introduce TDESKTOP_DISABLE_LEGACY_TGVOIP
+
+Originally from Alt Linux[0], OpenBSD has so far adapted the removal of
+tgvoip in the official net/tdesktop build.
+
+tgcalls provides everything needed for calls;  audio/video/desktop
+sharing calls have been working fine across different operating systems
+and telegram desktop/mobile versions without problems.
