A Comprehensive Guide to Cloud-Based Phones 2025

Communication costs can be a significant drain on company resources, whether you are running a small enterprise or heading a large corporation.

In light of this, investing in fully hosted and managed internet calling systems, such as cloud-based phones, can be transformational for your business. This is especially true for industries like hotels, healthcare, real estate, retail, and customer support, where reliable communication is crucial.

Cloud phones use Voice over Internet Protocol (VoIP) technology to conduct and receive calls over the internet. This reduces the overall operational costs for client-facing departments like sales and customer support across the organization. Research by Zippia suggests 82% of businesses report cost savings after moving to the cloud.

With the right cloud-based phone system, you can increase agents’ productivity and streamline communications to support the growing needs of your business. 

In this article, you’ll get a comprehensive overview of cloud-based phones, including what they are, how they work, and how they stack up against traditional phone systems. We’ll also dive into who they’re for, their pros and cons, and must-have features. 

Key takeaways: 

1. Cloud-based phones, using VoIP technology, significantly reduce communication costs and enhance operational efficiency.
2. Cloud-based phone systems come with advanced features like voicemail, call routing, analytics, and AI-driven functionalities.
3. CloudTalk is highlighted as an exemplary choice for businesses prioritizing AI integration and advanced analytics. It offers robust features such as intelligent call routing, sentiment analysis, call recording, and monitoring.

What Is a Cloud-Based Phone?

Cloud-based phone systems are a type of business communications solution hosted over the internet, eliminating the need for a traditional analog phone system. They use VoIP technology to manage calls and offer features like dialers, call routing, and analytics. 

Since these solutions store all call data off-site in the cloud instead of a server, like an on-site Private Branch Exchange (PBX), your information remains secure against any malicious agents. 

You can also save on maintenance costs since everything can be easily updated in the cloud.

How Does a Cloud Phone Work? 

Cloud phones work similar to a regular phone, except you use the power of the Voice over Internet Protocol (VoIP) technology to place your calls instead of traditional phone networks. 

When you dial a number, the call is routed via:

1. Translating analog speech impulses into packets of data
2. Sending those data packets across your internet connection

Once the data packets are received at the other end, your VoIP provider converts them into analog speech signals that the person on the other side of the call gets to hear.

Due to the nature of cloud-based phone solutions like CloudTalk, you have complete control over business phone numbers, call forwarding, user additions, and other features via an online real-time dashboard.

9 Must-Have Features for Cloud-Based Phones

If you’re looking to integrate cloud-based phones into your business, it’s important to know what features you should look for in your cloud-based phone system provider.

Here are nine must-have features for cloud-based phones: 

1. VoIP (Voice Over Internet Protocol)

Cloud-based phones use Voice over Internet Protocol (VoIP) technology to send audio and multimedia data over the Internet, replacing traditional phone lines.

VoIP enhances call quality through advanced codecs and reduces latency. It also significantly lowers costs by eliminating the need for dedicated phone lines and offering lower call rates, especially for long-distance and international calls. 

VoIP also supports scalability, easy integration with other digital services, and advanced features like call forwarding, voicemail, and conferencing. This makes it an efficient and cost-effective solution for modern communication needs.

Benefits:

• Cost-savings
• Scalability
• Flexibility
• Easy maintenance 

2. Auto-Attendant

An auto-attendant phone system is a cloud phone service feature that automatically answers and routes incoming calls based on the caller’s input or pre-defined rules. 

It uses Interactive Voice Response (IVR) technology to offer menu options for directing calls to appropriate individuals or departments.

Benefits:

• Efficient call routing reducing wait times
• Consistent greeting and user experience
• Cost savings on hiring live operators
• 24/7 availability ensuring calls are always managed

3. Call Forwarding

Cloud-based phones offer advanced call transfer features that route and forward direct incoming calls to the appropriate person or department based on pre-set criteria.

This ensures that calls are handled efficiently, reducing wait times and improving customer satisfaction.

Benefits: 

• Better customer service
• Efficient call management
• Improved productivity
• Business continuity 

4. Unified Communications

Cloud-based phones work on a unified Communications-as-a-Service (UCaaS) model. This means they connect with various other cloud communication platforms and collaboration tools, such as CRM, email, chat, and video conferencing, and unify them into a single platform. 

With these systems, you can transfer your phone calls to the cloud and integrate them with your instant messaging, CRM, video conferences, and other business procedures. 

However, while all cloud-based phone systems integrate with popular tools, it’s important to find one with a broad palette of integrations. This way, you can make sure it works with systems you’re already using and increase the software adoption rate. 

Benefits:

• Reduced response times
• Improved data sharing
• Better customer support
• Efficient workflow management

5. Analytics and Reporting

Cloud-based phones offer advanced call analytics and reporting features that centralize your team’s data. This helps managers access in-depth insights to assess agent performance, identify patterns and anomalies, and optimize communication strategies. 

These solutions track call center metrics, such as duration, frequency, and resolution times. 

With call center analytics software like CloudTalk, you can track everything that happens during your inbound or outbound call journeys, decipher call statistics and performance indicators for individual agents or entire groups. Plus, you can narrow your search with filters ranging from call statistics to agent performance and team overview. This can help your business refine processes, improve service quality, and make data-driven decisions.

Benefits: 

• Performance tracking

Benefits: 

• Enhanced record-keeping
• Improved accessibility to call content
• Reduced information silos
• Training and development opportunities 

7. IVR (Interactive Voice Response)

Interactive Voice Response (IVR) is a more conversational alternative to automated customer service. It uses pre-recorded messages and menu options to interact with callers, collect information, and direct calls.

The IVR feature improves customer satisfaction by providing 24/7 service, freeing up human agents for complex issues, and enhancing overall call management efficiency.

Benefits:

• Efficient call routing
• Reduced wait times
