Pattern¶

This is the most widely used Extension Node.

The corresponding tree is entered if extension that is called (or entered) by the caller matches the configured pattern. Initially Pattern Extension Node has pattern of "_X.". This pattern matches any digit.

There can be several Pattern Extension entrance points for particular Call Handler. In case if there several Pattern Extension Nodes, each of them must be assigned a priority. Initial priority is 0. The node with greater priority will be checked before the node with smaller one.
