[Asterisk-Users] How to program Phone "Configurable line indicators" for some PSTN lines

[Miroslav Nachev]

   Hi,

   I would like to program some PSTN lines to be indicated on the
phone (GXP-2000) when are busy and etc. How can we do that using
"Speed Dial/Configurable line indicators" or/and "Line 1-4 Keys"?
   How Asterisk will inform the phone when the line is busy or
ringing, etc.?


   Best Regards,
