Call park identifier for Cisco 7861 phones

We are deploying Cisco 7861 phones for our Webex migration. One of the issues we're seeing is when using call park when the recall timer expires the call rings back to the Line 1 number that it came in on but if there are several calls parked the screen cuts off the park extension that is being recalled. It's due to the space as it will show the caller ID and then VI... so it runs out of space to display the call park extension. Another option to solve this would be to flash the button assigned to the parked call when the recall timer expires. We chose the 7861 as we had already deployed several hundred and wanted to stay consistent with our legacy configuration.
