It is beyond frustrating to switch desk phones between users in RC admin portal, especially if the user needs to switch to an unassigned phone.
Please, add a dropdown under the user which allows you to select the phone assigned. Put the same dropdown under the phone itself to select an assigned user. This way it is intuitive.
And please stop putting us through the order process to 'order' a phone I already own and charge me for a new line I don't need. This complicates the whole process and is unnecessary.
