First of all, I want to introduce the step of how to install a network address book.
1 Setup Ftp server
In this ftp server
Ftp user name:vp9035(in the left side)
Ftp password:vp9035(when we set the ftp finish, when we check in the next time ,for the secret it
will be empty)
2 Root directory
There must have two files. One is Netaddrs.vcf（name be this）another is Version.txt
Netaddrs.vcf is the address book.
Version.txt like this will be right. “ ver：YYYY.MM.DD.VV（year，month，day，any number）”
when you change the network address book，this version should be changed.usually you should change the date will be finish.
