Benefits and Disadvantages Of Using Automated Voice Messaging

As with any software or service, there are benefits and drawbacks to using an automated voice message system. Although the advantages typically outweigh the disadvantages, businesses should still know all details and information about the chosen software or API. Here is a quick rundown of some of the benefits involved with voice messaging:


Voice messaging and voicemail drops are incredibly flexible and can be used for many different purposes, regardless of what industries a business may be involved in (as detailed in the previous section)


Because you can automate nearly every step involved in voice messaging software, businesses have to invest significantly less time and resources in manually calling customers, including time for creating scripts and scheduling the actual calls.


Investing fewer resources while increasing output means that your business saves money since those resources can either be scaled back or redirected to areas of your business that need more attention.

These are just a few benefits businesses can leverage if they integrate voice messaging into their communication and marketing campaigns. However, there are not just benefits to using this medium but also drawbacks that businesses should understand. Some of these include:


Integrating a voice messaging API can be daunting for businesses, especially those who do not have IT departments experienced with coding or programming APIs.


Unfortunately, there are no automated voice message free services, which means that your business will need to budget for the service; while the cost-savings you receive in the future offset these initial costs, they still need to be addressed.

Learning Curve

Most APIs and software are designed so that users can quickly pick up how they work. However, businesses will still have a learning curve when transitioning from manual to automated messaging, which may temporarily slow operations.

FAQs About Automated Voice Messaging

Many businesses have questions about automated voice messaging and how it works, which they want answers to before signing up with a service provider. To clarify, we answer some of the most frequently asked questions.

How can I add a voice messaging API to my business?

Suppose you sign up with a service provider that offers an API. In that case, your business will need a software developer or programmer to integrate the API into your existing project.

This will involve writing code. More specifically, your business must add a web reference to your application, allowing it to call on the API for processing. Esendex's API can be integrated using any language that can make a REST or SOAP call, including C#, Java, Python, Ruby, PHP, and Node.js.

How can I test a voice messaging API before sending a real campaign?

Many businesses want to test their software or APIs before using them in real-time. Your business can use test credentials to test a voice message API, which should have been provided at sign-up time. Test campaigns will not be sent out to customers; your business should not be charged for these tests.

Is voice broadcasting legal? Will my business get in trouble for using it?

Voice broadcasting is legal if companies follow all rules and regulations set by federal agencies like the Federal Communications Commission (FCC) and Federal Trade Commission (FTC). These regulations dictate what content can be included in the messages, to which the messages can be sent, and when the messages can be sent. Your business remains compliant with regulations. Your communication and marketing campaigns are legal.
