/* !TODO!:
 *  + Cisco Format Mac
 *  + Model Information
 *  + Device Right Menu
 *  - Dial Templates are not really needed for skinny, skinny get's direct feed back from asterisk per digit -->
 *  - If your dialplan is finite (completely fixed length (depends on your country dialplan) dialplan, then dial templates are not required) -->
 *  - As far as i know FreePBX does also attempt to build a finite dialplan -->
 *  - Having to maintain both an asterisk dialplan and these skinny dial templates is annoying -->
 *  + Dial Templates + Configuration
 *  + Dial Templates in Global Configuration ( Enabled / Disabled ; default template )
 *  ? Dial Templates - Howto IT Include in XML.Config ???????
 *  + Dial Templates - SIP Device
 *  - Dial Templates in device Configuration ( Enabled / inheret / Disabled ; template )
 *  - WiFi Config (Bulk Deployment Utility for Cisco 7921, 7925, 7926)?????
 *  + Change internal use Field to _Field (new feature in chan_sccp (added for Sccp_manager))
 *  + Delete phone XML
 *  + Change Installer  ?? (test )
 *  + Installer  Realtime config update
 *  + Installer  Adaptive DB reconfig.
 *  + Add system info page
 *  + Change Cisco Language data
 *  + Make DB Acces from separate class
 *  + Make System Acces from separate class
 *  + Make Var elements from separate class
 *  + To make creating XML files in a separate class
 *  + Add Switch to select XML schema (display)
 *  + SRST Config
 *  + secondary_dialtone_digits = ""     line config
