Users currently have the ability to display the ring group label (ring group name) on the agent side. It will be displayed like this:

To enable this, simply navigate to Campaigns -> Custom Data (From the admin app). Ensure You have a field named InboundSource as a custom field (You do NOT have to make it visible for this to work). Reference this guide on how to add a custom field

Please keep in mind that should should actually add a label for the DID. To add a label, navigate to Inbound -> Call Flows & Call Queues, then click the Call Queues tab (from the admin app).

From here, double click the cell under the "Ring Group" column to show a text box. Simply type the ring group name, then press the enter key and you're set!
