Graphs and Nodes
A Graph is a logical road map within the VMS which enables callers to easily navigate through the system and
reach the desired destination (person in an organization) by following voice prompts and dialing appropriate digits.
A Node is a logical stopover point in a graph where some activity like making a decision, leaving a message,
accessing information, etc. is made.
A Graph is thus a logical and meaningful association of different nodes. A graph initiates from the ‘Root Node’ and
traverses through different nodes.
The following figure is a logical representation of a simple graph with 6 nodes:
Six-node Graph
Callers must dial appropriate digits while traversing through the graph to reach the desired destination. Single digit
codes are used to navigate within a graph.
While traversing through the graph, the VMS uses voice messages to prompt callers at every step so as to enable
them to reach the desired destination.
Let us take the example of the 6-node graph illustrated above to understand graphs and nodes. In this 6-node
graph, the caller reaches the Root Node by dialing the digit '0'. The Root Node is the entry point of the graph.
At the Root Node, the VMS offers the caller different options like leaving a message, accessing Company
information, have the call transferred to a mailbox, or a particular extension, operator, or department.
For each option, the VMS prompts the caller to dial a particular digit. Each option takes the caller to a particular
node.
• Dialing '1' at the Root Node takes the caller to the Message Node.
• Dialing '2' at the Root Node takes the caller to the Information Node.
• Dialing '3', '4' or '5' at the Root Node will take the caller to the Transfer Node.
The caller decides which path to take and dials the single digit code for the desired path announced by the VMS in
the voice prompt.
