3CX Android will always show contact details from the phone address book, overriding caller ID info from the PBX, including route/ring/queue name. This means operators managing multiple incoming identities will never know which identity is being called if there is a contact that matches the incoming number. For companies who synchronise their 3CX with the same Exchange server as the mobile phone uses, this will be all Exchange contacts. What we need is the option to disable 3CX client from matching the incoming number against the phone's internal contact database for incoming calls for those who need this important 3CX destination target feature. I am not sure if this is an issue on IOS as I don't have an Iphone to test. 3CX Windows has no problem with displaying the incoming call route.
