Parking Lot Returned Call Behavior Alert-Info/CallerID Prepend not working

Running FreePBX, without parking pro. I have configured parking lot alert info and Caller ID Prepend and the callerID is unchanged and the SIP packet does not have an Alert Info section in the header. Is this now a licensed “Parking Pro” module feature only or is something broken?

Sounds like a bug in Park. Please open a bug report.
