Linphone and Raspberry Pi Python script call on button press problems with setting PATH

I have installed linphone with the following guide: https://wiki.linphone.org/xwiki/wiki/public/view/Linphone/Linphone%20and%20Raspberry%20Pi/

I have fiew to none experience with python.

I found a script that reacts on a button press and this seems to work, but the command I want to make is not working.

My Script:

#!/usr/bin/python

import RPi.GPIO as gpio
from subprocess import call
import time
import subprocess
import os


gpio.setmode(gpio.BCM)
gpio.setup(5, gpio.IN, pull_up_down = gpio.PUD_UP)
os.environ['PATH'] = '/home/pi/linphone-sdk/build-raspberry/linphone-sdk/desktop/bin'

subprocess.Popen(["sudo -u pi linphonecsh init -a -C -c /home/pi/.linphonerc -d 6 -l /tmp/log.txt"])

def doorbell(channel):


    subprocess.Popen(["linphonecsh dial **9"])
    
gpio.add_event_detect(5, gpio.FALLING, callback=doorbell, bouncetime=300)

while 1:
    time.sleep(360)

I get this error

FileNotFoundError: [Errno 2] No such file or directory: 'sudo -u pi linphonecsh init -a -C -c /home/pi/.linphonerc -d 6 -l /tmp/log.txt'

This seems to be the case because the PATH variable is not set right. I also tried to set the PATH in the "/etc/rc.local" like in the guide is set. Also I tried to set it in /etc/crontab.

How do I set the Path right?

Since you are using python to make your script, why not build the linphone SDK's python wrapper? https://gitlab.linphone.org/BC/public/linphone-sdk#python-wrapper-wheel-packaging

This way you can more easily control your calls etc...
