I would apprecicate your help here. Thanks in advance.
I am confused about what value needed to be specified with those 5
paramaters in the LinePickup().
The status is ext 01 called ext 202, internal call. Ext 102 is ringing.
In TB20 steps as below:
(in this situtation, both sets are speaker phone set)
Openline ext02 (specified LineDevID, returned got LineHandle "11123")
Openline ext01 (returned got LineHandle "11145")
LineMakeCall (default in TB20, using ext01 line handle, call ext02
,specified ext02 linehandle, returned call handle 11778)
.. Ext02.. Ringing...
LinePickup ()
(Below I must did something wrong, and your help will be greatful)
hLine:
Handle to the open line device on which a call is to be picked up.
What is that means ? in this case which handle , 1145 or 1123 ?)
dwAddressID: Specified
Address on hLine at which the pickup is to be originated. An address
identifier is permanently associated with an address; the identifier remains
constant across operating system upgrades.
I can not understand what it means here again.
"at which the pickup is to be originated" Can't understand this statement?
lphCall: I guess this is to be a returned value for the call handle when
function is completed.
lpszDestAddress
Pointer to a null-terminated character buffer that contains the address
whose call is to be picked up. The address is in standard dialable address
format.
I don'tknow why I can't understand this statemen, "that contains the
address whose call is to be picked up." Which ext is it means here? ext01
or ext02. What that address would be?
lpszGroupID
Pointer to a null-terminated character buffer containing the group
identifier to which the alerting station belongs. This parameter is required
on some switches to pick up calls outside of the current pickup group.
I assumed that I can ignore this one and specify NULL here. Because I am
having the ringed extension 02 set to picup its own call. It is not a group
pickup in this case. But I am not sure.
All I know is whatever the value combination of above that I specified in
LinePickup () , I can't make it work.
Anyone like to help ? Thanks, again.
