iPhone 6 getting missed, outgoing and incoming calls from other phones with my same Apple and iCloud id.

I Just got the iPhone 6s and is mixing up calls with the other phones signed in my iCloud. Ive turned off 'calls on other devices' On all phones. I Have 'Handoff' off in all phones. 'Send & receive' on messages and FaceTime is also of on all phones. The problem still persists I don't know what else could be the problem.
