How did we choose the best virtual PBX?

Before choosing a virtual PBX for your company, you should take into account the basic needs you have to cover. For example, what size of company do you have, do you plan to continue growing your business, what CRM tools do you use and are they compatible with the PBX you are considering? The list of 12 virtual PBXs you have just read reflects to the 12 most complete PBXs we have found in the market. In addition to being flexible and having some of the most important functionalities, they offer very affordable plans for those who are looking for a slightly simpler cloud communication solution.

What is a PBX in a company?

A business PBX is the platform or department, physical or virtual, responsible for organizing and managing the telephone communications of a business. In the past, these switchboards were departments of people who made connections between incoming calls and recipients manually.

Over time, procedures and devices evolved into a telephony solution that made connections in a simplified manner. The person at the switchboard who received the call could transfer it to the correct recipient by specifying a series of specific numbers, called extension numbers, corresponding to that person or department.

However, thanks to the digital transformation and the emergence of new platforms adapted to the needs of a new and growing market, cloud communication solutions like virtual PBX were developed. These solutions use IP telephony as the basis for all the actions and functionalities they offer.

Remember that IP telephony is telephony that transmits data over the Internet. This means that the devices used for this will be software, i.e. programs or applications that can be used from any connected device, resulting in considerable savings in material.

What types of PBX switchboards are there?

As we have mentioned above, PBXs have undergone a great positive change since their beginnings back in 1878, when telephone switchboards were manual. Today, there are four types of PBXs: analog, digital, virtual and multiline. Let's take a closer look:

• Analog: The traditional PBXs of all life. These are the most limited PBXs in terms of features, they can only send voice and fax.
• Digital: They use the so-called Integrated Services Digital Network (ISDN) to transfer information over copper wires. This type of PBX began to add extra functions such as the possibility of placing a call on hold.
• Virtual PBXs: These are PBXs that use the VoIP protocol to transmit voice and data over the Internet. They are also known as cloud PBXs because they are software that can be accessed at any time from anywhere with Internet-connected devices.
• Multiline: These are PBXs that combine the three previous ones, using hardware and software. It may seem a bit cumbersome but the advantage of using different types of lines is that if one goes down, you do not run the risk of losing all connections.

What does a PBX do?

A telephone switchboard is a hardware device or virtual application that manages and unifies all telephone connections in the same place, whether it is a small office, a larger one comprising an entire building or even a geographical area. These PBXs link calls between different users by establishing connections.

The users that go through the PBXs can be the company's own employees, using an internal network of extensions determined for each department or person, and external users: customers or prospects calling to get more information or resolve doubts.

What is an IP PBX?

It is the natural evolution of the traditional analog or digital PBX. Instead of using copper wires to transmit information from telephone connections, the VoIP PBX or IP PBX uses LAN and WAN networks to transfer voice and data over the Internet, as its name suggests (IP stands for "Internet Protocol").

Best Cloud PBX FAQ

What is a cloud PBX?

Cloud PBX (private branch exchange) is a business phone system that runs on a managed service in the cloud. Many companies subscribe to a SaaS to have a cloud PBX service, which brings many advantages to a business. A virtual PBX system allows for flexibility, integrations with other business software, and valuable performance insights thanks to analytics dashboards.

What is the difference between PBX and VoIP?

There is very little difference between cloud PBX and VoIP. However, traditional PBX is very different from VoIP because PBX is based on landline telephones and VoIP sends calls over the Internet.

Why use a cloud PBX?

A virtual PBX provides a lot of flexibility. You'll be able to choose how to route your calls, and employees will be able to connect to their virtual PBX service through any Internet-connected device. Plus, you'll be able to scale your business easily because virtual PBX providers often offer multiple plans depending on the features needed.

What are the benefits of a cloud PBX?

Other advantages that we can find once your company has adopted cloud telephony as the basis for its communications are:

• Flexibility. The fact that you can use it from anywhere allows you to be flexible and adopt a hybrid work model, authorizing your teams or agents to telework or work remotely on certain days of the week. In case you need to have some control over your teams, many cloud-based PBXs for companies offer real-time monitoring functionalities so that you don't miss anything about your teams' work and performance.
• All in one. In general, a PBX in the cloud presents a fairly extensive list of extra functions. These include automatic call forwarding, agent performance statistics, call recording, creation of virtual numbers, IVR... All in a single interface. Depending on the type of communications and team management you need, you will have to choose one solution or another.
• Integration with your CRM. This feature facilitates data collection and promotes teamwork, since the information on the various interactions with contacts and prospects is stored directly in the commercial tool you have and this, in turn, is integrated with your business PBX. Immediately access the file of one of your contacts in order to improve your sales performance.

These, together with the cost savings in material and maintenance, make cloud PBX for companies the ideal platform to elevate your conversations and turn them into a real competitive advantage.

How to create a company PBX?

Creating a company PBX is very simple, especially if you install a virtual PBX. All you have to do is follow five simple steps.

1. Find a provider that fits your needs. Choose one that offers specific extra functionalities for some kind of problem you want to cover. For example, if you need to improve the coaching of your equipment, choose one with a dual listening or whisper function. If you would like to have more than 1 unified channel and, for example, the ability to create SMS campaigns, choose a contact center.
2. Once you have chosen your provider, the first thing to do is to open the application and assign administrator and user roles, limiting and privatizing permissions to avoid manipulation. Administrators are those with access to almost all functions, users will have specific and more reduced permissions.
3. Now it is time to create an IVR that allows the caller to select the department (or person) he/she wants to speak to directly. Create an interactive voice menu that allows the caller to select the department they want to contact. You can configure the welcome message to provide information about customer service contact hours or even add answers to common questions. You may be able to resolve the caller's question before he/she transfers the call to an agent.
4. Set your business switchboard hours to avoid being disturbed outside your office hours. You can model an answering machine message that informs you of the times when an agent will be available. If it is a 24-hour business, you can set up an automatic forwarding to support agents who are on call.
5. Finally, integrate your PBX with your CRM business tools. This is one of the main features of the PBX in the cloud, as it allows you to automate the collection and organization of data from all contacts that go through your company's PBX.

And now you can start using your virtual PBX, it's that easy!

What is needed to install a virtual PBX?

There are not many technical requirements to install a cloud PBX. The basic and important thing is to have a good Internet connection and an Internet-connected device: smartphone, tablet or computer.

One of the added values of virtual PBX is that you can install and configure it yourself. In case you need support, an agent will be connected at all times to follow the process and guide you in those moments when you need it.
