I have a R20BX3. I need the "http://IP_of_AKUVOX/fcgi/do?action=CallEnd" to work. It works with my "firefox 101.0.1" perfectly. It does not work with "Edge", nor with "Firefox es", and it does not work with curl (curl http://10.0.0.77/fcgi/do?action=CallEnd, or curl " http://10.0.0.77/fcgi/do?action=CallEnd") What can I do that it will work with curl?
