Does this article still apply? I can't get it to work with version 15.5 and yealink phones. https://www.3cx.com/blog/docs/call-parking/ To park a call should just be a blind transfer to *05 (*0 to park and 5 being the number of the parking orbit) To unpark a call it should just dial *15 (*1 to unpark and 5 the number of the parking orbit). What am I missing? Thanks.
