Procedure
HCXTD850, Rev. A02, September 2001
U
To transfer a call using the switchhook-flash-to-trunk
feature:
1
While connected to a caller on a trunk set up for
switchhook flash to a trunk, press <OVR> (the
override key).
When you press this key, the HCX system sends a
switchhook flash signal to the central office, placing
the caller you want to transfer on hold.
2
You receive dial tone from the central office and can
now transfer the call using standard Centrex transfer
operations. See your system administrator for the
Centrex transfer procedure.
Note: You cannot perform switchhook flash to a
trunk if you are already connected in a
multi-party conference using more than one
trunk. In a three-party conference, you can use
this feature if you first disconnect one of the
parties to which you are connected.
