[2020] VoIP blocked by ISP (can't listen or talk to teammates in game)

VoIP ingame is blocked, my ISP which is in Egypt (WE) blocked Vivox related traffic which is responsible fro VoIP transmission and I can't use voice chat in game to communicate with my teammates.

I had to run a batch file to unblock the voip and it worked but it's no longer working,

this is the code:

@echo off
:: BatchGotAdmin
::-------------------------------------
REM --> Check for permissions
>nul 2>&1 "%SYSTEMROOT%\system32\cacls.exe" "%SYSTEMROOT%\system32\config\system"

REM --> If error flag set, we do not have admin.
if '%errorlevel%' NEQ '0' (
echo Requesting administrative privileges...
goto UACPrompt
) else ( goto gotAdmin )

:UACPrompt
echo Set UAC = CreateObject^("Shell.Application"^) > "%temp%\getadmin.vbs"
set params = %*:"="
echo UAC.ShellExecute "cmd.exe", "/c %~s0 %params%", "", "runas", 1 >> "%temp%\getadmin.vbs"

"%temp%\getadmin.vbs"
del "%temp%\getadmin.vbs"
exit /B

:gotAdmin
pushd "%CD%"
CD /D "%~dp0"

ECHO Starting RainbowSix Voip Routing
set ip="IP Address"
rem set ip="IP Address"
for /f "tokens=3 delims=: " %%I in ('netsh interface IPv4 show addresses "vpn" ^| findstr /C:%ip%') do set ip_address=%%I
route add 74.201.103.0 mask 255.255.255.0 %ip_address%

This used to unblock the VoIP but since the game update it no longer does, I have tried everything in the support page which said to open ports and to no avail, this is the only thing that fixed it, so I would like you to help me by changing anything in the code so it can unblock the VoIP again.
