Whether you’re looking to make a simple VoIP call, create a cloud IVR, or build a conversational AI bot, you’ll need to know the basics of what to look for when choosing a provider to build with.

This three-part blog series is a comprehensive guide to building, scaling, and enhancing your voice solutions. In part one, we’ll cover the foundations of building future-ready voice solutions, specifically diving into global coverage, redundancy, and call quality.

Why do voice solutions still matter?

Despite the rise of messaging and video tools, 69% of employees still say voice communications strengthen their relationships with colleagues. Meanwhile, 65% of consumers continue to expect to reach businesses over the phone. These statistics show that consumers still rely on phone calls for business communications. Robust voice solutions meet those demands.

However, as voice communications evolve, and businesses must adapt to those similarly evolving demands. To build truly future-ready voice solutions, it’s essential to understand the trends driving the development of voice technologies.

2024 voice communication trends

Like many technological fields, 2024 brings global connectivity and AI to the forefront of communications. Here are the top trends companies should consider when developing their voice solutions for a changing world:

Remote and hybrid work

The rise of remote and hybrid work models has changed how employees communicate. Reliable, high-quality voice solutions are critical to ensuring teams remain connected and collaborative, regardless of location. Voice communication, alongside video and messaging, enables seamless teamwork, building stronger relationships across distributed workforces.

API-driven telephony

API-driven voice solutions are the backbone of scalable, customizable, and efficient communications systems. APIs allow businesses to integrate telephony capabilities into their applications and services, enabling greater flexibility and control over call handling, routing, and user experience.

Artificial intelligence (AI)

AI continues to play a transformative role in voice communications. From improving call quality to providing real-time transcription and translation, AI tools are enhancing customer experiences. AI-driven call assistants and analytics can optimize the flow of customer interactions, making every call more valuable and insightful.

Being able to take advantage of trends and new technologies is only beneficial if you have a strong foundation for your solutions.

What to consider when choosing a voice provider

Your provider plays a big role in coverage, resiliency, and call quality. Here’s your telephony infrastructure 101 for what to consider when choosing a voice provider to innovate with:

Global coverage to keep up with growing markets

As businesses expand, voice solutions must keep pace with a global customer base. Reliable global coverage is essential for businesses that need to deliver a seamless communication experience across borders. Here are some factors to consider when it comes to global coverage:

PSTN replacement

PSTN, built on outdated analogue equipment, is expensive to maintain and is being phased out globally. Modern voice solutions offer fully-featured telephony services in specific countries or regions, eliminating the need for businesses to rely on PSTN infrastructure.

Access to numbers

A licensed carrier can tap into a large inventory of local, toll-free, and national numbers, extending your global reach. An API-driven approach allows businesses to easily pull the necessary number provisioning and requirements, making the process seamless.

Compliance

Compliance is non-negotiable in voice communications. Adopting SHAKEN/STIR protocols helps reduce robocalls and increase trust in your voice communications. Additionally, seamless number porting ensures businesses can switch providers without losing their phone numbers. E911 functionality guarantees that emergency calls can share accurate location data with first responders—an essential feature for any comprehensive voice solution.

Redundancy to ensure consistent, reliable communication

No voice solution is complete without robust redundancy measures. The nature of cloud-based voice communications allows for flexibility, scalability, and, most importantly, reliability.

Cloud infrastructure

With multi-cloud and bare-metal infrastructure, cloud-based voice systems offer built-in redundancy. Modern cloud practices allow businesses to operate with a level of resilience that traditional voice solutions can't match.

Global Points of Presence (PoPs)

Having PoPs across four continents allows businesses to distribute voice services globally, reducing the risk of regional disruptions. With a presence in key markets, companies can ensure high-quality voice experiences for their customers anywhere in the world.

Carrier-grade redundancy

By partnering with multiple carriers, providers can dynamically route calls through the most stable and efficient paths, minimizing the risk of dropped calls or poor-quality connections. A multi-carrier approach ensures calls are always routed through the best available option, enhancing reliability.

Call quality for better customer satisfaction

At the heart of every voice solution is call quality. Poor-quality calls can damage customer relationships and result in frustration. Ensuring high call quality is vital for delivering the best experience possible.

Private network vs. public network

One key differentiator is the use of a private network versus a public one. Leveraging privately owned fiber interconnects between PoPs and carriers creates a private highway for voice data traffic. This approach improves security and provides low-latency communication—essential for ensuring high-quality voice interactions.

HD voice codecs

HD voice codecs offer significantly better sound quality than traditional narrowband codecs, reducing latency and providing crystal-clear conversations.

Noise suppression

In today’s mobile world, noise suppression is a must. Whether you’re calling from a bustling city or a noisy café, advanced noise suppression technology ensures voices remain clear and natural. For businesses using conversational AI, clear input signals result in more accurate and effective interactions.

Visibility and monitoring

To maintain high call quality, continuous monitoring is essential. Debugging tools give businesses real-time visibility into the performance of their voice systems, ensuring they can quickly identify and address any issues.

After evaluating key factors in selecting a voice provider, the next step is building a solution that prepares your business for future communication needs.
