So I reached out to Yealink, as once I configured 3CX Ring groups, I keep getting: Note: X New Missed Call(s) On all my handsets. The answer was: If you want the phone do not show the missed call when the call is pickuped by others in the group, just let the sever send the CANCEL message with the detail: Reason: SIP ; cause=200 ; text="Call completed elsewhere" That means the call is picked up in elsewhere. Thank you. How do I configure this within 3CX Thanks!!!
