3cx intergration batch file remove + from variable

[Jbotman]

Hello, I have made a intergration with 3cx in a batch file to open a new window with a specified url.
The number is filled in correctly

@echo off
start "Chrome" chrome --app=https://mywebsite.com?number=%1

My %1 variable contains a number of the caller, but it also contains a + before the number.
How am I able to remove this + from the number variable in a batch file?

you can leave the + and transform the + in the outbound rules if your provider does not support it.
Strip Digits 1 and the + is removed before we call the number...
