Upgrade to WhatsApp API Without Losing Voice Calling: Why Voice Is a Necessity

Messaging has never been more prevalent than it is today. With emojis, memes, GIFs and endless texts, it might seem like voice calling is fading from relevance. But nothing could be further from the truth.

Here’s why voice calling is still holding its ground:

Builds Trust and Adds Personalization

You just can’t beat an authentic human voice when establishing rapport with a lead or customer. It’s reassuring and adds a personal touch to the conversation, making the listener understand that they’re actually talking to a real person, not another faceless chatbot.

Just think about it. If you were a customer or lead, would you rather resolve complex issues or share your sensitive information (e.g., bank details) via a chat or over a phone call? We’re not saying voice is better than chat, but when used together, it can bridge the gap between impersonal messaging and genuine human interaction.

Reduces Miscommunication

Text-based messages are a breeding ground for miscommunication. How many times have you sent a genuine smiley face only for it to be interpreted sarcastically? With voice calling, you can cut through the ambiguity. Tone, inflections and instant back-and-forths all come together to provide clarity that texts lack.

While chat works well for quick updates or simple questions, voice calling provides the nuance needed for complex scenarios and is something especially important if you operate in mission-critical sectors like healthcare, finance or law.

Resolves Complex Issues Quickly

Time is money, therefore wasted time is wasted money. Imagine trying to explain the full value of an intricate product or service to a potential customer over chat. Tricky, right?

Now, we’re not saying you can’t do this over chat, but when it comes to sales, voice calling can just about give you that edge for complex issues. Voice calls let you explain the finer details, tackle objections in real time and build trust with a human connection.

Helps You Stand Out

So many businesses nowadays seem to be doubling down on chat, chatbots and automated responses, so it’s probably a good idea for you to do so, too. But then, when everyone seems to be doing the same thing, how do you differentiate yourself?

Simple. You use voice calling. When combined with chat, your messaging strategy becomes all the more versatile and can appeal to a much wider audience, letting you tap into that previously untapped segment of the market.

Difficulties When Upgrading WhatsApp API Without Losing Voice Calling

Now that you know the whys behind using voice calling, you might be wondering about the hows. Unfortunately, when upgrading the WhatsApp API, integrating voice capabilities isn’t so easy.

Here’s why it’s a tricky process:

Limited Voice Support in API Transitions

WhatsApp API upgrades often focus on improving messaging capabilities, overlooking voice features. This oversight can potentially create temporary service gaps that disrupt workflows, frustrate businesses and diminish the reliability customers expect from your communication channels.

Technical Complexity of Combining Voice and Messaging

In WhatsApp's architecture, voice and messaging services run on separate systems, and combining them when upgrading to WhatsApp Business API requires careful coordination.

WhatsApp uses WebRTC for real-time communication, but challenges like minimizing latency and integrating with Customer Relationship Management (CRM) systems can crop up along the way.

Regulatory and Compliance Hurdles

WhatsApp strictly mandates user permissions for business-initiated sales calls, and every API update requires meticulous compliance checks, including adherence to relevant regulations such as the GDPR. Miss something, and you’re staring at potential legal troubles!
