My call log is being duplicated on all phones
I have about 20 iPhones on our business account and after the latest update to iOS 9.0.2 some of them are receiving one another's call logs. Before the latest update, turning Handoff Fixed this issue.
Each employee uses their own Apple ID. I use one iCloud account on all of the phones to enable find my iPhone, all other iCloud features are turned off.
Is there a fix for this besides creating separate iCloud accounts for each phone? That would be a complete nightmare for me to keep track of.
iPhone 6, iOS 9.0.2
