Description
Conditions
105 2-152
This feature provides the ability to send a double switch-hook flash out
over a trunk. Flashing over a trunk enables a telephone on the PBX to
use CENTEXfeatures. Callers must follow the instructions specified by
the local central office concerning when a double flash should be used.
A CENTREX caller can put a CENT/EX extension on softhold and dial
another extension (by sending out a Flash Over Trunk followed by the digits
of the extension). If the caller hears busy or ringing, the caller can put the
CE/VTEX extension on softhold again, and dial the Double Flash Over
Trunk feature access code. This sends out two flashes on the trunk, with one
second between the flashes. When the CENTREX service receives the
double flash, it clears down the ringing/busy tone.The caller returns to a
talking state with the trunk that was on softhold.
The following conditions apply to this feature:
