Phonebook Directory tweaking

My config:

Asterisk 11
FreePBX 2.11
Phonebook Directory

So I’ve been reading this, which seems very interesting :

While it partially works, not everything is at my taste.

Note : I did not enter anything in the “ASTERISK PHONEBOOK”

#1 : Only if you enter the first three letters of the FIRST NAME will it work. How can I make it so it also works for the LAST NAME ?

#2 : If there’s a “SUFFIX” in the name, it will not work at all

#3 : It does not play the name recorded in the voicemail settings

#4 : I cannot change the language of the voice prompts

Please help!

Thank you!
