I have a situation where from time to time, another cell phone (not my own number) is being forwarded to my phone - I am aware of this happening, it is for my work. After a week, the phone is then forwarded to someone else, but I have to rely on those doing the forwarding to stop it to mine - is there a way for me to stop the forwarding on my phone? Or does it have to be stopped on the phone it is being forwarded from?
