Introduction

Have you ever thought about how you can reduce the workload of your employees and still achieve a high level of customer satisfaction?

Self services are the answer! These can help you automate processes and enable customer service even out of normal hours. 

As an example, we show you how to build a self service application for recording electricity meter readings!.

Neccesary prompts

First of all, the necessary prompts must be are created. 

The following table shows the prompts required.

TTS

You can create the prompts quickly and easily using a TTS engine if you have subscribed to our TTS service. This is shown in the screenshot below.

List - Checking Meter Numbers and Recording Results

A list is used to check the meter numbers and store the results.

The list is pre-loaded with all existing meter numbers. This can, for example, be manually loaded into the system, or imported using an FTP job.

The results in the list list could be automatically processed by exporting the list to an FTP server.

The fields in the list are as follows:

This is shown in the screenshot below.

Possible Call-Flow for the Self Service

The call flow for the self service might look like this:

An Explanation of the Important Objects Used

In this section we explain the key objects used in the call flow above and how it works.

Note - not all objects are explained - a basic familiarity with the jtel IVR is assumed. 

Enter Meter Number

/ Enter Meter Reading

These use Input This uses an Input Digits DTMF object objects to ask the customer to enter the meter number and the meter reading.

The counter number can only be entered after the beep because the check mark behind the field Beep is set.

Here is the parameterisation for entering the meter number.

Image Added

An audio beep is played after the prompt, to inform the caller that now is the time to start typing in the meter number (Play Tone). However, Barge-In is also selected so the Barge-In means that this announcement does not have to be listened to completely, but can be interrupted by starting to type in the meter number.

The minimum and maximum number of digits can be used for a plausibility check, for example, if the meter number may have a maximum of 10 digits then this can be specified as the upper limit.

Further explanations details on this object can be found in the WIKI under the following link:here: Input Digits DTMF - jtel Portal WIKI - jtel Public WIKI

2. Object List Lookup - This object checks the input of the meter number ($input) against the entries in the Self Service Meter Reading list.

Check Meter Number

The meter number is checked for validity by looking up the value - $input - in the List "Meter Readings". All meter numbers should be loaded into this list in order that the service may work as built here.

Image AddedImage Removed

This object has two outputs.

• Found -

• $input was successfully found in the list of meter numbers.
• Not found -

• $input was not found in the list

• . In this case, no

• self service is available and the caller

• could be connected to an agent.

3. Objekt Declare variable - Saving the entered meter number in the variable meter number, whereby the caller's input is in the variable $input and is therefore used as the initial value.

4. Object Play voice in combination with the object Output Variable

Further explanations can be found in the WIKI under the following link. following link:

Play Voice - jtel Portal WIKI - jtel Public WIKI

To play the input back to the caller, an announcement is played that reads out the variable counter reading.

5. Object Input Menu DTMF

This object is used to confirm that the counter reading was entered correctly by pressing selection 1 or to repeat the entry by pressing any other selection.

6. Object Jump to Target

This object is used to jump to a defined point in the routing. In our example, to the target object Input meter reading.

7. Object target oject

A target object is defined when the routing becomes complex and the arrows between the objects are no longer comprehensible at first glance.

8. Object Log Entry

Durch die Nutzung dieses Objektes wird ein Logeintrag im Callog erzeugt und die Fehleranalyse erleichtert.

Remember the inputs: meternumber / meterreading

If the meter number is found, we need to remember this for later. This is achieved by saving $input to a variable $meternumber using the Declare Variable object meternumber in the call flow above.

Similarly, when the meter reading is entered, this is saved to a variable $meterreading in the Declare Variable object meterreading.

Further details on this object can be found here: Declare Variable

Saying the Current Meterreading: say meterreading

This object is used to output the current meter reading as a concatenation of single digits. It is used after the "Current Reading is" prompt is played.

It is parameterised like this:

Saving the result: Remove old Reading / Add new Reading

The meter reading is saved to the same list in our example call flow.

This involves deleting the old entry and adding a new entry with the same meter number using two instances of the List Functions object.

Removing the old entry is performed like this:

And the new reading is added like this:

Keeping it Tidy: Jump Input Again / Input Again

These two objects are used to define a point in the routing, to which the call flow can jump, and to perform the actual jump from the end of the call flow to the middle.

Of course, one could just connect the two objects directly together, but the number of connectors involved will mean the end result might look somewhat untidy.

Further details on these two objects are found on the following pages: Jump to Target, Target

Conclusion

We hope this tutorial has given you some insight as to how a simple self service can be built using the jtel system. 

The logic can be changed and adapted as the use case requires.

Here are some examples:

• Save the readings to a new list only containing the readings recorded
• Check the meter number using a checksum algorithm if available
• Query a backend system by REST to check the meter number and record the results directly
