Replace TFTP with FTP for SIP phone configuration

Sections: 

These are my notes on how I replace TFTP with FTP for Aastra SIP phone configuration files on a Redhat Enterprise Linux server.  With the TFTP port exposed to the internet and no IP restrictions for remote phone configuration the directory is wide open.

Aastra XML scripts part II, auto-provisioning and auto setup with RPMS

In previous posts I showed how to auto-provision and configure Aastra phones by manually installing XML scripts.  Aastra has released RPM packages for Trixbox that combines everything and adds new features as well as mDNS so the phones can find the TFTP server even if you don't have a DHCP server capable of assigning it.  The script won't install unless mDNS is installed.
