Best VoIP Systems

Efficient communication is undeniably the key to any business’s success. Although email and instant messaging have become the pillars of modern correspondence in the workplace, there is still an ever-present need for phone systems.

Thanks to advancements in technology, businesses are no longer required to subscribe to expensive and complicated traditional telephone networks.

Instead, the best VoIP systems offer an affordable and straightforward solution that guarantees high call quality without breaking the bank.

Voice over Internet Protocol (VoIP) is a technology that allows you to make voice calls using a broadband connection instead of an analog phone line.

Depending on the virtual phone service, you may be able to only make calls from a computer or a special VoIP phone, but some services work with traditional phones connected to a VoIP adapter.

In a nutshell, virtual phone systems convert audio into a digital signal (called data packets) that travels over the internet. In cases where you’re calling a normal phone number, this digital signal is then converted to a regular phone signal before it reaches the destination.

Since virtual phone systems only require an internet connection, you can make calls wherever you are as long as you either have a Wi-Fi, ethernet, or cellular data connection.

SIP vs VoIP

As the name implies, Session Initiate Protocol (SIP) is the technology used to initiate, maintain, and end multimedia sessions within VoIP applications. More than voice, these sessions can also include video, fax, and messaging in a call.

SIP enables SIP trunking, which acts as a virtual phone line that also uses packet switching to connect calls. In other words, it works the same way as VoIP.

The main difference is that SIP trucking supports video, messaging, and fax (in addition to voice).

So, VoIP and SIP aren’t totally separate from one another. In fact, SIP (and SIP trunking) is a subprotocol that enables VoIP.

While VoIP is an umbrella term that covers many voice communication protocols, SIP is a protocol that explains how VoIP calls are established, maintained, and disconnected.

Types of VoIP services

There are various types of VoIP service. Something as basic as making a call on Teams is considered VoIP. The most common ones are:

• On-premise VoIP: A modernized version of the traditional POTS where all the hardware and connections of the VoIP system are deployed and maintained within the company. While more secure, it’s the most expensive solution and requires a dedicated team of technicians.
• Hosted VoIP: The most common VoIP service deployment, in which the system provider maintains all the hardware, and your business just needs to supply the phones and internet connection. Although it’s more affordable, it’s important to bear in mind that the company’s communication will be reliant on this provider to maintain 24/7 uptime.
• Hybrid VoIP: Combines analog and digital components, making it a good option for businesses with existing phone lines or in the process of migrating from a traditional landline to VoIP. Despite being more expensive upfront, it provides higher flexibility and cost savings in the long run.

Fixed vs non-fixed VoIP systems

The main difference between fixed and non-fixed VoIP systems is that fixed systems require an associated physical location.

It might seem like a small detail, but it actually comes with some important differences that need to be taken into account when running a business.

While a fixed VoIP provides higher security and reliability, it’s more expensive and difficult to scale and port.

Meanwhile, non-fixed VoIP systems allow you to have a local presence even in places where you’re not located – but it has a higher potential for fraud.

VoIP hardware and equipment

The hardware and equipment you require for VoIP highly depend on the system you opt for.

The simplest systems available just require a computer and an internet connection, whereas the more complex ones may need a team of specialists to deploy all the phones and connections.

With this in mind, it makes sense to divide the type of equipment required into categories of essential and optional:

Essential equipment needed for VoIP

• Modem and router: For your business to have access to the internet, you’ll need a modem and a router. There’s no need for special equipment, but it’s important to guarantee a strong internet connection for optimal call quality. This can be done either by having the equipment you’re making calls with close to the modem or by using ethernet cables.

Optional equipment needed for a virtual business phone system

• Analog telephone adapter: Also known as ATA, analog telephone adapters allow you to use a standard phone to make calls over IP. One adapter supports one phone.
• VoIP gateway: Converts analog telephone signals into VoIP data packets, making it an essential piece of equipment for businesses that want to keep their original infrastructure of traditional phones. One VoIP gateway can handle dozens of calls simultaneously, so one is usually enough, even for large teams.
• VoIP desk phones: The VoIP version of traditional desk phones. They look like traditional telephones but work with VoIP and also come with buttons to hold, transfer, and make conference calls.
• IP PBX server: Only required for on-premise VoIP systems, an IP Private Branch Exchange (PBX) server works as the center of your phone system and routes the businesses’ calls through the appropriate channels.
• VoIP router: While not necessary, a VoIP router is configured to ensure higher call quality and reliability.

Business VoIP costs depend heavily on the phone system you decide to deploy, the provider you opt for, and the type of plan you go with.

Prices vary so much that it’s impossible to pinpoint an exact amount.

Still, a basic business VoIP system with a free phone number and unlimited calling within the U.S. can cost as little as $20 per user per month.

Of course, plans that offer more advanced call handling functions and other built-in communication tools are usually more expensive and can go up to roughly $40-$50 per user per month.

If you opt for a hosted VoIP system where you just make calls from your computer and cell, the entry cost is usually zero.

However, if you prefer a hybrid or even an on-premise solution, you need to keep in mind that the initial investment can cost several hundred dollars.

Finally, another aspect that highly depends on the provider is calling rates – especially international ones.

It’s essential that you go over these rates before committing to a solution to make sure you choose a provider that best suits your needs.

The best VoIP features you need will depend on the type of business you’re running. Still, there are some core functions that you should always look for:

• Call forwarding: Reroute inbound calls to a secondary device if the primary phone is unavailable.
• Call transfer: Transfers the call to a team member.
• Call queueing: Allows for calls to stay in the queue when the line is busy.
• Call recording: Records calls, which can be used for training, quality assurance, or saving key customer information.
• Voicemail-to-email: Sends a transcription of voicemails to the person’s email, ensuring no customer is overlooked. Voicemail-to-text is also a possibility.
• Auto-attendant: A voice menu system that transfers calls to the right people by directing customers to press a button that corresponds to a particular department or agent.
• Interactive Voice Respondent (IVR): Similar to auto-attendant, it routes calls by using prerecorded audio that tells callers to press specific buttons to reach the department or agent they need to speak with.
• Mobile app: A mobile app with a softphone is essential to make and receive calls on the go.
• Call analytics: Provides an overview of the calls made by everyone on the team, tracking metrics like calls made, calls missed, average duration of calls, and more.
• Third-party integrations: If you’re already using other business software, make sure the VoIP provider smoothly integrates with it.

Essential virtual phone systems integrations to look for

As already mentioned, Voice over IP integrations are key to ensuring a unified system for your business. The most common integrations you should look for include:

• CRM integration: Allows teams to easily include call logs, recordings, and more into CRM software.
• Social media integration: Lets employees quickly contact leads gained from social media by providing them a link to a call on Facebook, X, Instagram, or TikTok.
• Live chat integration: Makes it simple to jump from a live chat to a call to provide better customer service or close deals.
• Calendar integration: Hop into scheduled calls from your calendar with one click instead of manually doing the work. It also helps ensure that appointments don’t overlap.
• Online collaboration tools integration: If you’re using tools like Slack or Teams, this integration sends real-time notifications on activity, calls, messages, and schedules directly to the software.
• Zapier: Provides thousands of extra integrations to boost productivity even further.

The main reason why virtual business phone systems have become so popular is due to the high number of benefits it brings to the table.

It’s more cost-effective, provides excellent call quality, and improves productivity – just to name a few.

Still, as with everything, there are also a few drawbacks to consider, such as the susceptibility to network jitter or the incompatibility with older fax machines.

Any business that requires a phone line is a use case for VoIP, but here are the most common:

• Business communication: VoIP has revolutionized how businesses communicate. From much lower costs and accessibility to advanced features that anyone can set up, it’s no surprise that businesses from all industries are taking advantage of virtual phone systems.
• Remote work: It’s much easier to manage the phones of remote workers with a centralized VoIP system than a traditional phone provider.
• Call centers: Known for having a high volume of calls, Voice over IP decreases the cost of call centers significantly. In fact, call centers have an enhanced version of VoIP called contact center software at their disposal.
• International calling: International calling is extremely expensive with traditional phone providers. Not only are international call rates lower (or even free) with business VoIP, but some providers also include international phone numbers so that your business can have a local presence abroad.
• Healthcare: With HIPAA-compliant VoIP, healthcare businesses have an easier time communicating while ensuring patients’ sensitive information is secure.

On-premise and hybrid solutions are more complicated to deploy, as there are some additional steps to set up the equipment and hardware.

Businesses that decide to have everything in-house will require a team of experts to configure and maintain the system.

From setting up the servers to ensuring all desk phones are properly working, these technicians will be your best bet to guarantee a stress-free installation and continuous uptime.

As technology becomes increasingly more advanced, the best VoIP systems are bound to follow. AI has become more common, and it’s already being integrated into virtual phone systems.

In the future, we foresee AI becoming even more prevalent in business VoIP. From AI-generated voices for auto-attendants to complex IVRs created with just a few prompts and easier-to-understand analytics, we believe that setting up a comprehensive virtual phone system is going to become easier and more beginner-friendly.

We also predict a higher adoption of unified solutions, such as UCaas and CPaaS. Customers are getting more selective about being able to communicate with companies the way they prefer.

So, having an omnichannel system that allows a conversation to start on social media and end in a phone call will be necessary to provide stellar customer support.

On the other hand, online services are going to become less secure, as hackers are also evolving with the new technologies that are accessible to them.

As a result, it will be crucial for virtual phone system providers to invest in cybersecurity and keep up with the new threats that appear every day.
