A few weeks ago, I upgraded a customer from FreePBX 12 -> FreePBX 14, and I had a couple minor things to repair. Nice job Sangoma on the scripts!
I received a call today from the customer that their parking lot is broken. I tried it myself, and was unable to transfer a call to Parking Lot 70, the default. Tried both the BLF button and a manual transfer. Nope.
Looking at other posts on the web in various places, people were able to resolve by downgrading from Asterisk 13 to Asterisk 11. That worked for me too. I was running Asterisk 13.17.0 and using the standard parking lot FreePBX module 220.127.116.11
I will fire up my test box and see if Asterisk 14 works or not.
