Automate phone conversations with naked voice APIs, visual designers, or custom-built, managed voice applications. Discover the pros and cons of each option







<h2 class="wp-block-heading">Pros and cons of Voice APIs</h2>



Voice APIs provide the freedom to develop any feature, but they require your application to manage exceptions across telephony, networking, and security. 



While building a simple prototype is often straightforward, turning it into a finished solution demands more effort and resources than anticipated. Additionally, maintaining these applications requires specific skills that may fade if not consistently applied. 



<figure class="wp-block-image size-full"><img loading="lazy" decoding="async" width="1024" height="1024" src="/wp-content/uploads/2024/08/craftwork.png" alt="" class="wp-image-5611" srcset="/wp-content/uploads/2024/08/craftwork.png 1024w, /wp-content/uploads/2024/08/craftwork-300x300.png 300w, /wp-content/uploads/2024/08/craftwork-150x150.png 150w, /wp-content/uploads/2024/08/craftwork-768x768.png 768w" sizes="(max-width: 709px) 85vw, (max-width: 909px) 67vw, (max-width: 1362px) 62vw, 840px" /></figure>







Unless you’re a large enterprise with robust development capabilities and a core focus on building voice applications, we recommend against using naked voice APIs to automate phone conversations.



<h2 class="wp-block-heading">Pro and cons of visual voice designers</h2>



Visual designers eliminate the need for coding when building voice applications, relying on frameworks and standardized building blocks. For simple applications that fit within these frameworks, visual designers can be the best choice, significantly reducing setup and maintenance efforts as no specific skills are required. However, compromises may be necessary due to each designer’s limitations.



<figure class="wp-block-image size-full"><img loading="lazy" decoding="async" width="1024" height="1024" src="/wp-content/uploads/2024/08/modular-building-blocks.png" alt="" class="wp-image-5616" srcset="/wp-content/uploads/2024/08/modular-building-blocks.png 1024w, /wp-content/uploads/2024/08/modular-building-blocks-300x300.png 300w, /wp-content/uploads/2024/08/modular-building-blocks-150x150.png 150w, /wp-content/uploads/2024/08/modular-building-blocks-768x768.png 768w" sizes="(max-width: 709px) 85vw, (max-width: 909px) 67vw, (max-width: 1362px) 62vw, 840px" /></figure>







For example, the <a href="https://proximusapi.enco.io/asset/flexio/overview">Proximus NextGen voice service</a> excels in personalized voicemail-to-email use cases and modular call flows, such as speech-driven FAQ bots, automated phone operators, and more. However, for complex applications or specific features, visual designers can complicate or even hinder development.



Many companies use specialized partners to set up voice flows, allowing them to manage day-to-day changes and updates independently.



<h2 class="wp-block-heading">Pros and cons of managed voice applications</h2>



For many companies, partnering with a trusted provider to build and maintain voice applications is ideal. Managed voice applications, developed by specialized partners using voice APIs, support any use case without the customer needing to manage the complexities, you get them off-the-shelf, yet tailer made.



<figure class="wp-block-image size-full is-resized"><img loading="lazy" decoding="async" width="1024" height="1024" src="/wp-content/uploads/2024/08/offtheshelf.png" alt="" class="wp-image-5617" style="width:630px;height:auto" srcset="/wp-content/uploads/2024/08/offtheshelf.png 1024w, /wp-content/uploads/2024/08/offtheshelf-300x300.png 300w, /wp-content/uploads/2024/08/offtheshelf-150x150.png 150w, /wp-content/uploads/2024/08/offtheshelf-768x768.png 768w" sizes="(max-width: 709px) 85vw, (max-width: 909px) 67vw, (max-width: 1362px) 62vw, 840px" /></figure>







These applications can still support ‘functional APIs’, allowing customers to tweak call flows with custom parameters defined by the partner. This collaboration simplifies long-term maintenance and adjustments, requiring no specialized skills from the customer.

The shopping experience doesn’t start or end at the doors of your store anymore. Your customers are online 24/7. They expect a consistent experience in any contact with your physical store, web shop, after-sales service and more. On top of that, for many shops, being reachable on the phone is already a challenge, as shop employees are attending in-store customers.







Conversational messaging can help you solve both challenges at the same time

A personalized service increases basket size. Set up a&nbsp;<a href="https://proximusapi.enco.io/asset/interact/overview" target="_blank" rel="noreferrer noopener">customer interaction center</a>&nbsp;to expand the shopping experience beyond your store. Offer your customers various communication channels to inform and advise them: text, chat, callback, &#8230;



<figure class="wp-block-pullquote"><blockquote>80% of customers are more likely to purchase from a company that offers personalized experiences</blockquote></figure>







<h2 class="wp-block-heading">1. Your telephone ringing all the time?</h2>



Some of your customers might try to reach your store by phone while at the same time your employees are busy giving your in-store customer the attention they deserve. 



Nothing sucks more for a customer then to wait at the desk while an employee is calling or vice versa customers don&#8217;t want to wait to long on your IVR before hanging up frustrated.



<figure class="wp-block-pullquote"><blockquote>89% of customers who abandoned a company due to poor IVR service spent their money with a competitor</blockquote></figure>



<h2 class="wp-block-heading">IVR deflection to Chat: the way forward</h2>



Everyone is familiar with this scenario:



A customer phones a company and is told by IVR, “All our agents are currently busy. Please hold.” After holding a few minutes, the customer is told, “The current wait time is 10 minutes.”



Now, imagine a different scenario:



“The current wait time is 10 minutes.” And then the IVR system adds, “Would you like us to attend you on your preferred chat channel?”



The customer, who just wants to have their issue resolved, will most likely reply with an enthusiastic YES.



Long wait times and the frustration of a one-way voice conversation are an extremely negative experience for customers that can result in losing their business. This negative experience can transform into a key, positive customer experience like an IVR deflection to SMS, WhatsApp or RCS by deflecting them to a channel they prefer in less than a minute’s time.

The renowned full-service agency, FamousGrey, has developed a real time city guide for Visit.Brussels, called <a href="https://now.brussels/">now.brussels</a>. The app allows you to discover Brussels through the eyes of its true inhabitants.
&#8220;Brussels has a lot of beautiful places, many of them undiscovered by tourists, but known by the locals. Visit.Brussels came up with the idea of creating an app as part of a larger campaign aimed at French and Spanish tourists, that shows visitors where the hotspots are located at any time of the day, in real time&#8220;. States Maarten Breda, Experience Director at FamousGrey.
<img loading="lazy" decoding="async" class="aligncenter size-full wp-image-4446" src="/wp-content/uploads/2019/07/QuoteEN.png" alt="" width="700" height="250" srcset="/wp-content/uploads/2019/07/QuoteEN.png 700w, /wp-content/uploads/2019/07/QuoteEN-300x107.png 300w" sizes="(max-width: 709px) 85vw, (max-width: 909px) 67vw, (max-width: 984px) 61vw, (max-width: 1362px) 45vw, 600px" />
<h4>About now.brussels</h4>
If the user allows the app to determine his location, he can start using the city guide. Hotspots are available in 3 categories: eating, drinking and doing. Based on location, weather, choice of category and preferences of the locals, a suggestion list is created. What is Brussels doing at this moment? The app provides a map that show blue and yellow spots. The spots indicate where the locals and tourists are located.

<h4>Innovative with real time data</h4>
FamousGrey and Proximus are already working together today. &#8220;At FamousGrey, we always try to keep up with the latest Proximus technologies and solutions. We try to use them creatively and integrate them into solutions and campaigns aimed at our customers. For example, someone noticed Proximus&#8217; recently launched Real Time Crowd Management technology and matched it to the needs of the city of Brussels.&#8221;
FamousGrey uses the <a href="https://proximusapi.enco.io/asset/rtcm/overview">RTCM (Real Time Crowd Management) API</a> of Proximus EnCo. Via the microsite on <a href="http://enco.io">enco.io</a>, you can easily define certain zones and retrieve data about them over a predetermined period. The creation of the most interesting zones for the Now.Brussels app happens automatically, thanks to the availability of the API. This way FamousGrey retrieves data every day. The tracking happens at the highest granularity (100m x 100m).
The zones have been defined both in collaboration with the Tourist Office and based on social media messages of Brussels residents, from which data is retrieved in real time. &#8220;The zones form blocks next to each other on the RTCM microsite, but in the app these zones are flattened to &#8216;liquid shapes&#8217; to obtain a visually attractive and well-arranged layout. The API then allows for the automated creation of data streams on the defined zones, with new data streamed every 5 minutes. The map is therefore updated every 5 minutes in the app.&#8221; According to Arno Van Biesen, web-developer at FamousGrey.
&#8220;In a second phase, it is anticipated that the &#8216;liquid shapes&#8217; will also move in real time. But this processing was not the initial focus, so that is what is currently being worked on.&#8221;
<h4>What does the future hold?</h4>
Visit.Brussels will be running the now.brussels app during the summer. After this period, an evaluation will be done based on usage and user feedback to decide whether the app will remain available on the longer term for visitors.”

FamousGrey & Visit.Brussels launch a real time city guide

Maddalena s.p.a. is an Italian company providing water readers that are frequently used in Belgium and across Europe. Water meters such as the PR-MWM can detect the lowest flow rates (from 0.5 liters / hour). So this makes them, according to this company, “the ideal meter for billing cold water consumption in collective housing”.
Maddalena understood the market&#8217;s need for connected meters quite well. So they teamed up with Kerlink to create a LoRaWAN™ add-on radio module. This module makes it possible to collect water consumption data over long distances. Its battery life can last up to 15 years thanks to the low power requirements of LoRaWAN and an optimization in the way this module works.
<img loading="lazy" decoding="async" class="aligncenter size-full wp-image-4390" src="/wp-content/uploads/2019/05/Image1.png" alt="" width="700" height="250" srcset="/wp-content/uploads/2019/05/Image1.png 700w, /wp-content/uploads/2019/05/Image1-300x107.png 300w" sizes="(max-width: 709px) 85vw, (max-width: 909px) 67vw, (max-width: 984px) 61vw, (max-width: 1362px) 45vw, 600px" />
<h2>Payload challenges</h2>
As you may know, there is no unique or universal payload format definition when it comes to LoRaWAN. Every vendor uses the protocol’s payload capacity to his own liking. Some use it adhering to format such as Cayenne LPP, but most implement their own format. When it comes to utility meters (such as for water or electricity), vendors tend to adopt mostly the Wireless M-Bus (Wireless Meter-Bus) protocol and adapt it over LoRa MAC in our case. The Maddalena LoRaWAN add-on module for the MWM water meters has taken this approach and uses Kerlink’s OpenAMR-MBUS payload formatting.
<a href="https://www.proximus.be/en/id_cl_iot/companies-and-public-sector/solutions/connected-business/internet-of-things.html?">Proximus MyThings</a> can offer payload decoding for many known LoRa device vendors such as Ascoel, eWattch, Adeunis, Sagemcom, etc. But when it comes to Maddalena connected meters over LoRaWAN, there is some additional payload deciphering to deal with.
On top of the standard LoRaWAN network and application encryptions, the Kerlink OpenAMR format implies that data coming from the same meter will be further enciphered. You can use a set of different encryption keys for each device. This means that each message coming from the same device may be using a different encryption key. Obviously, the set of keys is different for each device. This extra encryption/decryption raises the complexity on the end-to-end flow. Meaning that either your LoRaWAN provider has quite advanced payload decoding capabilities to offer or you need an extra application stack on your side to decode the data payload before injecting it in your metering or reporting solution.
<h2>EnCo CloudEngine Maddalena module</h2>
<img loading="lazy" decoding="async" class="size-full wp-image-4400 alignleft" src="/wp-content/uploads/2019/05/Image4-1.png" alt="" width="300" height="250" />
In April, we&#8217;ve added a Maddalena decoder module in the <a href="https://proximusapi.enco.io/asset/cloe/overview">Proximus CloudEngine</a>*. Resulting from our continuous effort to facilitate the integration of IoT data coming out of our LoRaWAN, M2M and soon NBIoT networks.
*As a reminder: the CloudEngine (CloE) is an event hub with an Integrated Development Environment (IDE). CloE ingests events from multiple sources, routes to multiple external sources and allows data transformation via advanced scripting in the middle.
<h4></h4>
<h4>Step 1: Maddalena decoding</h4>
For Maddalena decoding, we need to provide the module with:
<img loading="lazy" decoding="async" class="size-full wp-image-4399 alignright" style="margin-top: 0.857143rem; margin-right: 1.71429rem; margin-bottom: 0.857143rem;" src="/wp-content/uploads/2019/05/Image5.png" alt="" width="300" height="300" srcset="/wp-content/uploads/2019/05/Image5.png 300w, /wp-content/uploads/2019/05/Image5-150x150.png 150w" sizes="(max-width: 300px) 85vw, 300px" />
<ul>
<li>the DevEUI from the LoRa network (64-bit unique device identifier on LoRaWAN networks)</li>
<li>the hexadecimal message to be decoded</li>
<li>the LoRa port to which this message was sent or FPort. Because it will be required for the Initialization Vector to decrypt the ciphered payload</li>
<li>an array of the keys that can be used to decode payloads from the device</li>
</ul>
The CloudEngine’s Configuration Store is used to store a text file associating the DevEUI with the multiple device-specific encryption keys. This file’s content just needs some structure, such as comma or semi-column separated fields.
<h4>Step 2: CloE script</h4>
The second step is to create a CloudEngine script that ingests data coming from Proximus’ LoRaWAN network (ie “Proximus MyThings”). For each incoming Maddalena message, the script needs to:
<ol>
<li>Extract the necessary data from the incoming message: DevEUI, FPort and hexadecimal undecoded payload</li>
<li>Parse the stored text file containing the device decoding keys to fetch this device’s specific keys</li>
<li>Decode the payload using the CloudEngine Maddalena module. This is most probably the simplest part of the script, just a single line like this: 
object valueArray = maddalena.decode(deveui, payloadObject, port, keysForDevice); 
The script returns an array with all decoded values contained in the message, like the example below: 
[2019-04-29T00:00:00=259, 2019-04-30T00:00:00=259, 2019-04-28T00:00:00=259]</li>
<li>Send each of the decoded readings to the desired platform using the CloudEngine outbound modules. Outbound modules such as Microsoft Azure Event Hub or IoT Hub, SAP IoT Leonardo, HTTP, MQTT, sFTP, etc.</li>
</ol>
You can find a complete example script in the inline documentation of the Maddalena module in the Proximus EnCo CloudEngine.

Decoding OpenAMR payloads for Maddalena LoRaWAN water sensors

Today, all types of organisations in many different sectors get confronted with the need for digital transformation. As was Goodplanet at the end of 2017. Together with Proximus they were able to take the first steps into the world of IoT to help them measure the impact of their activities.
Goodplanet is a non-profit organisation that is active in environmental education and sensitization for 20 years now. They work mainly with schools and companies to educated and sensitize them in different environmental fields. Their main topics are nature, food and circular economies.
In the organisation, several employees are managing projects from the office in Brussels. Other collaborators are active in the field to do coaching and raise awareness. “We reach about 500,000 people a year with our many different activities&#8221;, says Clément Magos, responsible for innovation and IT projects at Goodplanet.

<h4>Measuring is knowing</h4>
&#8220;Today we are affected by the issue of impact and the need to measure the social impact of our activities&#8221;, says Clément. Of course, this applies for all organizations in the sector. As a result of that challenge, Goodplanet and Proximus started the conversation on how they could help realize this need. &#8216;We looked into the IoT technology and services that Proximus had to offer. Soon, we found a way to implement this technology into multiple projects. We are now able to measure the impact of our activities and the evolution in behavior of our audiences on several environmental subjects. The combination of Proximus MySense, the LoRaWan IoT network and the MyThings and CoudEngine platform made this possible.
<h4>Collect data on used transportation to school</h4>
To gather this valuable information, Proximus and Goodplanet created the so called &#8216;Kiosks&#8217; to set up surveys, using IoT technology. The kiosks are large panels with an integrated series of MySense sensors with push button. Goodplanet assigned a question and answer to each one of the sensors, related to topics like mobility and nutrition.
<img loading="lazy" decoding="async" class="size-full wp-image-4177 alignleft" style="font-size: 1rem;" src="/wp-content/uploads/2019/03/blok.png" alt="" width="300" height="200" />
One of the surveys done, was measuring the students&#8217; choice of transport to school. &#8220;In the past, no data was available on that matter&#8221;, says Clément. Tracking the evolution in the use of transport means and how that’s related to Goodplanet’s and the school&#8217;s activities is valuable information to their daily business.
They asked the following question in 8 different schools: &#8220;how did you come to school this morning&#8221;? The answers to choose from: &#8220;on foot, by bike, by car or by public transport&#8221;. Next, all the students had to do, was choosing the suitable answer by pushing the matching button. “It all seems simple, but in our sector it&#8217;s a big step ahead. This system offers a lot of advantages, unlike the paper surveys that were done before”, says Clément.
<ul>
<li>It gives us more certainty on the data quality</li>
<li>It allows larger scale data collection</li>
<li>It allows us to handle more themes in the same period of time</li>
</ul>
<h4>This is how it works technically</h4>
Every time someone presses a button, it sends a message over the Proximus LoRaWAN network. Each button on the deployed panels is battery operated. They have a lifetime of multiple years, because our Low Power LoRaWAN network. Therefore the schools do not need to provide any kind of local connectivity.
The Proximus MyThings platform receives and decodes the messages emitted by the buttons. Decoded messages are automatically pushed to the Proximus EnCo CloudEngine platform. On CloudEngine, 2 scripts have been implemented:
<ol>
<li>The first script <a href="https://docs.enco.io/docs/using-google-api-from-encoscript">creates a new Google Sheet document</a> every first day of the month and saves this new sheet reference on the platform. Thereafter an email is sent to the GoodPlanet administrator to inform him the sheet and online reference was created successfully.</li>
<li>The second script receives decoded messages coming from the buttons over the LoRaWAN network via MyThings. It extracts meaningful information fields from these messages and adds them as a new data row in the Google Sheet.</li>
</ol>
Working with Google Sheets makes it easier for GoodPlanet to use the collected information. Indeed, GoodPlanet is not a large IT shop with tens of developers. Neither does it have an IoT platform with analytics at hand. Using modern, every day online tools such as Google Sheets allows them to easily plot and graph the data just like in Excel. But they can <a href="https://blog.enco.io/blog/bridging-iot-and-legacy-systems-with-cloudengine-1-csv-file-generation/">export this data in any suitable format</a> (csv, XLS, …) for consumption by another service.
<h4>A platform to collect, monitor and visualize 
 <img loading="lazy" decoding="async" class="size-full wp-image-4203 alignright" src="/wp-content/uploads/2019/03/Platform4.png" alt="" width="400" height="206" srcset="/wp-content/uploads/2019/03/Platform4.png 400w, /wp-content/uploads/2019/03/Platform4-300x155.png 300w" sizes="(max-width: 400px) 85vw, 400px" /></h4>
This survey system is part of the GoodSchool DigiTool project. Goodplanet and Proximus created the platform <a href="http://www.goodschooldigitool.be">www.goodschooldigitool.be </a>so schools can visualize and monitor the collected data from the sensors. It does not only contain information on mobility, but also on topics like energy, waste and nutrition.
Schools gain insights thanks to this platform and based on that information, they can sensitize their students and start concrete actions to improve the school&#8217;s sustainability.
