Well first i would wait about 2 weeks from the date you mailed it for it to show up online. and then wait until it says "in progress" then you can call up and get your interview done and then get the app ref# from them or it should be online as well and get your chaps to call in and press 1 then 1 then 2239.
HOWEVER if you are ONLY applying for non restricted there will be no interview for you or no need for your references to call in.
1. Don't wait until it is online, call before that and that often gets it online the next day.
2. PAL is PAL whether for unrestricted or restricted, not everyone has references called but calling references is not only for restricted applications.
