Receive calls with SIP

Hi, after all my edits, I finally can recieve a call with zoiper, I choose the “PBXww” option to forward, the problem is that the call rings at the app and at the cellphone simultaneously, how I can resolve this?

Glad to hear

Open the PBX/Phone system ( [My account > PBX][1])

Click the red X in the person module next to the forwarding you want to remove, either the SIP or the phone number forwarding
