Event Notify Procedures

Event notify procedures are an advanced VSI-FAX customization/integration topic. You may skip this section if you

are not interested in customizing event notifications.

Event notify procedures are scripts that trigger various system actions whenever certain events take place. This

entire notification mechanism is designed to be open and easily customized so that you can optimize each VSI-FAX

system to your particular needs.

This section begins with a general functional overview of event notify procedures. Flow diagrams show the various

notification points in the system and the various notify procedures run at each of these points. Immediately following

the functional overview is detailed information about how to write your own custom notify procedures.

Functional overview

At each different notification point in the system, VSI-FAX executes a hierarchy of notify procedures as shown in this

figure:

System notify procedures

System notify procedures are always performed first and automatically. Furthermore, although these scripts are found

in the VSI-FAX directory structure, they are not intended to be modified. If you do modify these system notify scripts,

you will lose your modifications the next time you upgrade your VSI-FAX system.

Site notify procedures

If they exist, site notify procedures are performed after system notify procedures but before any user or device notify

procedures. Site notify procedures are used to customize a particular notification point on a site-wide basis.

Site notify procedures are not supplied with the default VSI-FAX system-you must create them if you want to use

them, preventing unnecessary processing by the fax server.
