I'm having a beast of a time here, and hoping someone smarter than I can help I am working at setting up call parking with 3CX v9 and Cisco SPA509G phones. I have two unused line keys on my CIsco phone programmed for fnc=sd+blf;sub=SP0@$PROXY;nme=SP0 and for SP1. I can transfer a call by pressing xfer then the SP0 or SP1 line key fine, and it goes into the correct park slot and the line key lights red indicating there is a parked call waiting to be picked up. You can press the line key and pick up the parked call. Works perfect! Except... The call is not shown as parked in the 3CX assistant. Matter of fact, it doesn't appear ANYWHERE in the 3CX assistant. The other side of this problem is that when you park a call USING the 3CX assistant, it shows as parked in the 3CX assistant but does not light up the park line key on the phone, nor can you pick up the parked call from the phone by using the SP0 or SP1 line key. Someone help!
