I am trying to use the Web UI to setup Parked calls.

I have created the Parking Lot within the range of the Internal Context.

But I cannot get calls to transfer to the Parking Lot.

In Wazo 18.1, I had a note that said to use Park, Page or Pickup, I had to enable “dtmf transfer” by going to  
Services -\> IPBX -\> IPBX Settings -\> Users -\> Services -\> Services (tab)  
and Check Enable DTMF Transfers

I cannot find anywhere in Wazo 20.01 that I can Enable DTMF Transfers. Does anyone know where this is done or if it needs to be done in Wazo 20.01?

I also tried just manually using the txfr button on my Aastra to transfer the call directly to the Parking extension but that gave me the “Unavailable” error message. I did succecssfully manually transfer a call to another extension so the txfr button is working.

I think I have the Parking Lot setup properly:  
Name: MyParkingLot  
Extension: {extension number within the Internal Context}  
Slots Start: 1  
Slots End: 5  
Music On Hold: {my MoH\_set}  
Timeout: 30

If you see something wrong with this, please let me know.

I assume I start the Slots at 1 and end the Slots at a number that I expect will handle the max number of concurrent calls parked. Is this correct?

What that does is put the incoming line on hold and uses a new line to call the Parking lot then joins them. But I cannot use any of the star codes to transfer calls. Not BLind Transfer (\*1), not Attended Transfer (\*3). THis is true for teh Aastra phones and a Softphone. The DTMF codes are working when I join a conference and enter the PIN so that part appears to be working. Are there settin…
