This little script will generate a valid gs_phonebook.xml file from all extensions in FreePBX. The generated XML will be ready to be downloaded trough TFTP.

If there is a error or a improvement for this script, let me know :)

Remarks: I assume your TFTP server is configured to use /tftpboot/ as root directory. You’ll also have to set the correct settings inside your phones (or the end point manager) to force the phones downloading the generated gs_phonebook.xml from the server.
