This section presents VIV examples using a global collect variable type instead of the single digit value variable type. The value variable allows an FAC assignment so that the value of the variable can easily be changed by a dialing sequence. The global collect variable can be used in the same way, that is, by dialing a VDN instead of an FAC.

Global collect variables offer many advantages over the value variable, including:

• Global collect variables are not limited to nine FACs.

• The ability to add a security code to prevent malicious or accidental changes to the call flows.

• Creation of a VDN/vector menu that prompts for the variable to change (multiple variables via one VDN).

• Call flow routing can be changed remotely by calling the VDN rather than through remote access to dial an FAC.

• Additional features such as feedback announcements and confirmation.
