Many vectors use the same basic call flow, but are unique because each vector requires a different set of announcements, route-to destinations, holiday tables, vector routing table indexes, and conditional limits. With VDN variables, you can create a generic call flow vector. Use VDN variables to administer unique items on the VDN screen. VDN variables drastically reduce the number of vectors, ensure common flows and ease of administration during crisis times when you have to change the flows due to unforeseen events. Unforeseen events include problems with trunking, staffing, or messaging.

VDN variables enable VDNs to use a smaller set of vectors. You can:

• Assign up to nine variable fields, V1 through V9, on the VDN screen for each VDN.

• Use the VDN variables in all vector commands that support vector variables except as a for parameter with the collect-digits command.

• Use up to 16 digits to assign a number to the VDN variable and up to 15 characters to describe the VDN variable.

• Use VDN variables as indirect references to announcement extensions and other numerical values in vector commands.
