Variable Forward No Answer Operations Guide Introduction
Chapter 1 Int roduction
The Variable Forward No Answer (VFNA) application allows a configurable
amount of time a call rings a phone before it gets forwarded to another extensi on.
Overview
The VFNA applic at ion de t ect s i n co ming calls and sets a timer accor din g t o t h e
value that corresponds to the extension receiving the call. The timer value is
maintained in the Applic ation Platfor m Manager ( APM) data base. If a nd when the
timer times-out, the call is transferred to an extension def ined in the APM database.
This ov ercomes the swit ch limita tion of a f orwa rd no answer global delay variab le
for all extensions.
The VFNA application is primarily designed to provide a back-up or "fail-safe"
method of detecting external equipment failures that result in phones ringing
unanswered. For example, if an IVR system goes down, calls to the IVR will ring
unanswered. Wi th the VFNA ap plication, the stations that are ports in the IVR will
be transferred to a manned extension or the operator.
Note: If the e xtensi ons that use VFN A have a f orwar d no ans wer functio n, thi s function
must remain off.
Note: If stations are transferred to voice mail, there is no voice mail integration. The
caller w o uld be transferred to voic e ma il as if they direct ly called voice mail.
The VFNA application works inside the general OAI system (Figure 1-1).

Chapter 3 Configuration
This chapter provides step-by-step instructions for configuring the VFNA
application.
Note: The VFNA installation process automatically performs all necessary
configuration functions. The section below entitled Modifying the Installed
Config uration shows you ho w to manually modif y these in stalle d parameters .
Databa se Administration
The Variable Forward No Answer application uses the APM database. The
database includes the following data items:
• Name - name of the station (25 characters max)
• VFNA station extension (5 digits max)
• Tenant number for extension (3 digits max)
• Forward phone extension (25 digits max)
• Timer v alue - number of seconds to wai t while no answer before forwarding
call (4 digits max)
Applic a tion Conf i guration Men u
A major element of OAI in the UAP is the Application Manager (APM), a set of
menu-driven softwar e which allows control of OAI processes a nd data access. The
Variable Forward No Answer application is incorporated into the OAI system by
means of the AP M. Certain i n fo rmation asso ci at ed w ith the ap p li cation m u s t be
made known to the OAI system. This is accomplished by using the Application
Configuration Menu of the APM.
User Defined Se tt ings
For the VFNA application to run properly, three user-defined settings must be
assigned: a monitored number, a monitored number tenant, and a forward
extension bus y ca l l n umber. Here’s how to do t h at.
1. Go to the System Administration screen.

Database Requirements

Step 1 - Create
Master Def inition File
Step 2 - Build
Master Database File
Step 3 - Specify
Application Formats
Step 4 - Process/Install
Applic ation Da tabase
• Step 1 - Create a Master Definition File: This step involves creating the
master definition file that defines the fields in the master database file.
• Step 2 - Build a Master Database File: This step involves entering data into
the master database fields that were just defined in the master definition file in
Step 1.
• Step 3 - Create an Application Definition File: In this step, a de f init ion f il e is
created for the master database. This file def ines the formats by which data from
the master file is to be converted to meet the needs of the VFNA application.
• Step 4 - Process and Install the Application Database: In this step, the
Process an d In s ta ll A ppl i cati o n D atabases op t ion on the APM Datab ase
Administration m enu creates t he f ile that will be u sed by the VFNA application.
When the Proces s o p t ion is activated, d at a is drawn from the ma s te r database
and converted to the formats specified in the application definition file. The
Install option is then activated to enable the VFNA application to copy its
database.
This operating guide will approach the subject as follows:
• Looking at your Default Database

Sample Database Entry
This is a sample setting of a database entry:
Name = Test
Extension = 1000
Tenant = 1
Forward Extension = 2000
Delay in Seconds = 10 seconds
This sample setting means that if the phone extension is 1000, it will ring for 10
seconds. If it doesn’t answer by then, VFNA will forward the call to extension
station 2000. Variable Forward No Answer, in plain English, means that the VFNA
database directs where and when to forward the call.
Specifyin g the Applicati on Database Fie ld
The VFNA application da tabase fie ld has already b een copied fr om the install ation
disk. Therefore, skip this procedure.
Processing the Applicat ion Databa se
After building the master database, it must be processed before the application is
able to use the data from the database.
To p roce ss the application database, do the following:
1. Go to the System Administration screen.

3. Perform the Processing the Application Database procedure detailed above.
4. Then perform the Installing the Application Database procedure detailed
above.
The standard application start-up is as follows:
1. The server comes up.
2. The APM platform starts up.
3. The VFNA application initializes.
Note: The assumption here is that the initialization batch option is set to Y. If it is
set to N, the application must be started manually.
To manually start the application, do the following:
Note: The assumption here is that the initialization batch option is set to N.
1. From the System Administration screen of the APM, select the Operations
menu.
2. Verify that OAI is initialized by observing the top line of the display. The
application manager should have an “*” at the end of the name. If there is no
“*”, selec t Initialize OAI, then press Enter.
3. Select non-crt application control.
4. Select I for Initialize, then pre ss Enter.
5. Select VFNA by moving the cursor and pressing Enter to highlight VFNA.
6. Press Escape.
7. Press Y at the prompt: Initiali ze select ed apps ? (Y,N).

User Tasks
There is no user interface to this application. VFNA becomes active when the APM
initializes t he VFNA application . It must be maintained by t he APM administr ator.
The administrator’s duties would be to add, modify, and delete records to the
VFNA APM da tabase.
Note: See the Data Requirements section for the fields required in the database.
