If the feature in enabled, it can operated in 2 different operation modes,
depending on the selection in AMO VFGR :
CHA-VFGR:ATNDGR=<nr>,TYPE=GENERAL,COD=ON;
With this setting the feature is enabled permanently.
For each extension with a diversion (CFU or CFB) a decision to STEP or
RING is necessary when it is requested. The DES button is without any
function.
CHA-VFGR:ATNDGR=<nr>,TYPE=GENERAL,COD=OFF;
With this setting the feature is enabled temporary and
the operator has to use the DES button to activate the feature for next
call before dialing is started. Toggling is possible in this state. The
information 'DES ACTIVE' is displayed or removed from the call
control window. If the dialed extension has CFU or CFB activated, so
the available information about the extension and diversion is displayed
and the operator has to decide to follow (STEP button) or override (RING
button) the diversion.
