Working with script variables
You can create up to 50 call variables. If you attempt to create one more
variable, you receive an error message.
Call variables and blind transfer calls
A blind transfer involves passing a call without notifying the recipient. It is also
known as unsupervised transfer or cold transfer.
When a contact arrives and executes a master script, the contact starts with an
empty list of call variables. Then, as the contact executes the scripts, each call
variable that it uses is copied into the list of variables for that script.
If the scripts are written so that the original incoming contact accesses some call
variables, and the consultation contact accesses different call variables, when the
transfer is complete (blind transfer only), a single list is created that contains
both the original contact call variables plus the consultative contact call
variables. The original contact starts again at the top of the master script, but this
time with the combined list of call variables. If the same call variable is used by
both the original contact and the consultative contact, the value of the
consultative contact is applied to the variable after the contact is complete. This
process occurs only for blind transfers.
What are wild variables?
A contact can use wild variables to change the value of a call variable of type
Integer and make the updated value available to other contacts.
A call variable becomes a wild variable when it is referenced by a script by using
the READVAR/SAVEVAR command block. The value of the call variable is
passed into the wild variables table. Another contact can access the saved value
in the wild variables table by using the READVAR/SAVEVAR statement. The
value is equal to the last value saved with the SAVEVAR command unless Task
Flow Executor (TFE) restarts or unless you initialize the value by using a
READVAR/SAVEVAR. Task Flow Executor is the name of the call flow
operation.
The TFE is the service that executes scripts and determines how all calls are
processed.
Wild variables can only be type Integer.
