I need to update the Device Description, Line Alerting, Line Description, and Caller ID for 800+ phones. I have created a proper Phone Format with the required fields, exported the proper fields and edited the file (like in the attachment), and re-uploaded the file. However, when I go to "Bulk Administration > Update Phones > Custom File" I am getting "0 Records Found" for any type of search there. I have tried both .txt and .csv custom files to no avail.
Am I doing something wrong here? Any tips on how to complete these updates?
