#1 CloudTalk

Cloudtalk’s Benefits

CloudTalk Voice provides high-quality offers, care, and service, all included in our business phone system solution.

  • Easy Management: Use CloudTalk’s web-based admin interface to manage your call center in real-time, add agents, phone numbers, and set up everything you need at any given moment.
  • Reduced Operational Costs: With our business phone system, you can significantly reduce your operational costs, as no special skills are required and there’s no need to hire extra IT specialists. CloudTalk can be managed in a user-friendly interface – all you need is an internet connection.
  • Accessible Anywhere: CloudTalk is a completely cloud-based business phone system – all you need is to set up your CloudTalk account. But don’t worry, if you already have an existing infrastructure, CloudTalk can be easily linked to it. Switch between your laptop and your cell phone easily.
  • Smarter Calls: Distribute all calls to your team in a smart way and view past customer interactions during the call to enhance customer experience. Native integrations with CRM, helpdesk or other popular apps boost your productivity and take lots of manual tasks out of your workflow.
  • SLA: A service level agreement can be provided for all CloudTalk PBX business phone systems, guaranteeing a maximum level of reliability and technical support.
  • Reliable Operation with 24/7 Monitoring: We always make sure your data and voice services are safe. All data (including VoIP itself) are stored in secured locations of Amazon AWS with 24/7 monitoring provided by CloudTalk experts.

Key Features

With CloudTalk advanced features, your phone experience will get to a whole new level.

  • ACD: Automated smart and efficient queue distribution of inbound calls based on all available data to make sure that callers are always directed to the most qualified agent or agent group.
  • IVR: Create your multi-level interactive voice response (IVR) menu to guide the caller through different options. Make sure they are always directed to the right department, agent or group of agents and that they are receiving relevant information through customized messages.
  • Call Queuing: Create customized call queues. Inbound calls are sorted in call queues based on pre-defined rules and steered to available agents within the right group. Personalized messages are available as well.
  • Call Recording: CloudTalk can automatically make a recording of all calls. Once the call ends, you can listen to it directly from your internet browser anywhere and anytime. Improve customer interactions by monitoring your team’s calls.
  • International Numbers: Acquire international numbers (with geographic or non-geographic codes) from more than 160 countries. Local phone numbers allow customers from abroad to call you at standard local rates or free of charge.
  • Real-time Customer Card: Your agents can see all caller information displayed in one place. During the phone call, they can instantly look at the client’s history of interactions, orders, chat, or notes. This allows them to deliver top-notch customer service.
  • Callback: If there are any unanswered phone calls, CloudTalk can automatically call your customers back. A missed call from a customer is registered in the system, which will later dial the customer’s number until the agent and the customer are successfully connected.
  • Business Hours: Define your business hours and decide when you are available for receiving calls. Outside of these hours, you can choose a special personalized absence message, redirect calls to a different phone number or answering machine or even use various combinations.

What is CloudTalk Missing?

According to our users, CloudTalk Analytics needed remastering in order to give users more precise data. That is why we launched a new version of Analytics with in-depth insights into your calls, including call steps, reasons for missed calls, and much more.

What Type of Business is It Best For?

Maximize Call Center Productivity with Advanced VoIP Features

CloudTalk offers a wide range of enterprise-level call center software features at a startup-friendly price.

How Call Centers Use VoIP Software

Small Businesses

It’s difficult to lead a small business, manage all the operational chaos, and be there for your customers all at the same time. With VoIP Call Center software, you can (virtually) be in multiple places at once. Route all incoming calls to your smart device while keeping your personal number private, or just take some load off your shoulders with auto-attendants and IVR.

Mid-Sized Businesses

Mid-sized businesses tend to have enough employees to take care of their operations, but onboarding new agents is still an issue. By using call monitoring, seasoned company veterans can help newbies and offer advice without the customer even knowing it, or jump into a 3-way call directly. Automatically dividing calls via ACD and setting up business hours for additional routing are only a few more invaluable features in the mid-sized call center toolbox.


With so many people, tools, and resources rubbing shoulders in one place, staying efficient is one of the biggest challenges for corporate call centers. Thankfully, tools like call queues and smart and power dialers can help cut down busywork significantly. Analytics help you keep track of every important call center metric, while inter-connected 3rd party integrations help to keep your business running smoothly.

How We Cut Revolut’s Sales Ops by 40 Hours per Month

Building the world’s first financial super-app and managing millions of monthly transactions is no simple task. After going global, Revolut learned this the hard way, and soon, the need to grow its sales teams became obvious. And although the company managed to scale its SDR count from 0 to 500+ in just 18 short months, it still lacked one thing – a unified call center solution. 

Revolut was looking for several things. A fast, reliable, and secure way to contact their prospects, easy access to actionable insights in their CRM, and the ability to easily expand into new markets. That’s when the company reached out toCloudTalk.

CloudTalk dramatically increased Revolut’s control over its inbound and outbound calling operations. Every sales agent’s work aspect can be monitored and tracked to improve performance. As a result, Revolut reduced sales operations by 40 hours per month, cut costs, and improved efficiency. 


How much does VoIP cost?

The cost of VoIP can vary depending on the provider and the features offered, number of users and the length of the contract. CloudTalk has 3 different plans: Starter at $25.00 per user per month. Essential at $30.00 per user per month. Expert at $50.00 per user per month.
To get an idea of what else you should consider except for price, you can check out our e-book “How to choose a VoIP package”.

How does call center software work?

Call center software is designed to help businesses manage their customer interactions more efficiently. The software can handle various tasks such as call routing, call queuing, call recording, and reporting. When a customer calls the call center, the call is routed to the next available agent based on predefined rules. The agent can access customer information and history to provide personalized assistance.

Call center software can also integrate with other tools, such as CRMs and help desk software, to provide a seamless experience. To learn more about how call centers work, check out our article on “How to start a virtual call center” on our blog.

How many VoIP providers are there?

There are numerous VoIP providers in the market, each offering different features and pricing plans. Some of the top VoIP providers include CloudTalk, RingCentral, and Nextiva. You can learn more about all of them on our page.
