Call park how in freepbx?

HI. I have tried to figure out how to park a call. I tried *70 , ##70 #70 without success

when I had astlinux. I have config a park for 15 sec. then if no one answer. then the call goes to the original extension. that is what i want to do but in freepbx i dont know how to achieve it

thanks so much for any help

Did you go into Module Admin and install the Parking Lot module? If so, it should appear in the left-hand menu. Go into that and set up a Parking Lot, using the options you want, then try parking a call using the extension number you assigned to the Parking Lot (transfer a call there using ## to get the transfer dial tone, then dial the Parking Lot extension - you should hear the pickup number read back to you).
