CTX 100 with IVP8 R1 for auto attendant. Call main line and auto attendant answers. Press 1 and it goes to MCG 600. It rings all the phones in the group, but after 9 rings it goes back to the auto attendant. I want it to keep ringing. In the MCG the system CF is 0, I have tried changing it to 1 and change the system CF to go to multiple different destinations but nothing affects it. Any help would be appreciated. Thanks
