Although you can sync bOnline Unlimited Calling with email and workspace platforms, it’s missing integrations with web conferencing, external and internal live chat, analytics, and SSO, and doesn’t have an open API. This might force your team to jump back and forth between different systems, slowing down your customer service speed.Onboarding support: available for Unlimited Calling subscribers.Scalability: although bOnline Unlimited Calling doesn’t limit your user numbers, and prepares you to deal with large numbers of callers thanks to call queue and ring groups, it’s not the easiest system to scale. It lacks internal live chat and web conferencing, which could complicate remote working. It also has a thin security barrier as it doesn’t have compliance certifications, multi-factor authentication, or user permissions.bOnline Unlimited Calling ComparisonsOur meticulous research has brandished bOnline Unlimited Calling with a 4.5 star rating for small businesses overall, placing it in the third spot of our top eight telephone systems for small businesses, bested only by 8×8 and Vonage.Although we’ve given it a 3-star rating for scalability as it’s missing a few key ingredients to help your business grow seamlessly, its price is pretty much unrivalled.

If you’re looking for a provider that has a track record of pleasing its users, you should look no further than Nuacom.Nuacom Unlimited FeaturesSoftware integrations: compared to other providers like 8×8, Vonage, bOnline, Nuacom has a limited offering of external connections. Although you can sync your telephone system with CRM, Helpdesk, internal live chat and email integration, you can only do so with a small number of platforms – only Hubspot, Slack, and Google Workspace. This means Nuacom is not integrable with Web Conferencing, external live chat, analytics, SSO, and does not offer an open API.Onboarding support: offered as a 15 minute onboarding support session.Scalability: with a requirement to have at least 2 users, Nuacom comes equipped with call queue and ring groups, which can help you manage a large number of callers. However, this isn’t necessarily the most scalable solution as you’d be missing out on a number of management features like customisable call routing, call monitoring, call-flow designers, and setting up teams. You also wouldn’t have access to video conferencing which can complicate keeping your team connected when working remotely.Nuacom Unlimited ComparisonsOur research has given Nuacom a 4.2-star rating, which places it in the fourth spot of our best telephone systems for small business comparison, right before GoToConnect. Nuacom’s average customer review score of 4.6 places it in the pole position of customer satisfaction, with bOnline racing close behind at 4.4, This places Nuacom in the pole position of customer satisfaction, with bOnline racing close behind at 4.4. That said, Nuacom scored just 2.6 for its features and 2 for security, so if you want lots of features and more stringently protected data, 8×8 or Dialpad would be a better phone system for your small business.

It also includes web conferencing and internal live chat if you’re happy to use Google Meet and Google Chat. Therefore, what it lacks in management features is made up for in terms of security, but keep in mind that this isn’t a golden solution to scale up your business.Google Voice Standard ComparisonsOur researchers have put the key features offered by Google Voice for small business to the test and have given it a 3.7-star rating. Whilst it’s a great option for Google users, its limited offer of features gives it a 2.6-star rating in this category.

Save by comparing prices for the right phone systems for your small business Do you already have a business phone system? Yes No Just answer a few questions – it only takes a minuteHow did we compare the best phone systems for small businesses?Our team of researchers has conducted an in-depth dive into the most used and best-rated phone system suppliers on the market. Prioritising all the possible features that small businesses might need from a VoIP phone system, we’ve narrowed it down to the top eight providers and their best subscription models for small businesses. They shine through because of their onboarding and management features, and their ready-made integrations that can help you strengthen your operation.We’ve also aggregated customer reviews from platforms like Trustpilot and Capterra to assure you that our knowledge is not only robust on paper, but also in practice. Regardless of which choice you make to meet the demands of your small business, our research-backed recommendations will match you with the most suitable players in the VoIP market.How to choose the right phone system for your small business?When making the crucial choice of which VoIP phone system to bring into your small business, there are a couple of key features that can help you make your decision less stressful and complicated. You can consider:Money: as is the case for a lot of things in business, money can be an inevitable pain point. Therefore, it’s important to prioritise options that charge low up-front monthly fees, offer inclusive domestic minutes, provide multiple communication channels (so you don’t have to pay extra to get these from other providers), and provide solid customer support, so you can avoid losing money during a potential phone downtime.Compatibility with your software infrastructure: when you’re entering the VoIP-verse, the last thing you want to do is spending aeons switching back and forth between all the software platforms you use to run your business. Therefore, choosing a provider with integrations is key. Look out for ready-made integrations for things like CRM, workspace, email, web conferencing, internal messaging, and external messaging platforms.Scalability: as a business, you can be burdened by extra costs in the long-term if you outgrow an important software system, forcing you to upgrade to a different provider. Therefore, you’ll need a VoIP system that can grow as fast as your business can. Key indicators for this will be providers that let you onboard an unlimited number of users, and come with call queues, ring groups, a good array of management features, and things that allow you to run your operation remotely, like internal messaging and video conferencing. Security will also be key here as this shields your business from risks as you expand.

Based on our in-depth research, we’ve found that the best options out there for small businesses are Vonage Professional and 8×8 X2. They’re relatively affordable, come with unified communications features, and they’re more flexible and easy to use both remotely and in the office – all points to consider if you’re a small business! If you want to learn more, scroll up and read our reviews of Vonage and 8×8. What is the best phone system for an office? When choosing what type of phone system to adopt, you have a bunch of different providers to explore – but the first hurdle you need to clear is whether your phone system will be VoIP or PBX. We recommend hopping onboard a VoIP phone as it allows you to easily keep your operation remote, flexible, and adaptable, and most importantly, cheap. In fact, if you want to think about it in another way, VoIP systems provide your business with the key functionality offered by PBX systems anyway, so you wouldn’t be missing out on anything by making a transition to VoIP. Then, which provider you choose should depend on the size of your business and what your specific needs are! You can read our review above for specific recommendations for small business. How much does a small business phone system cost? A small business phone system doesn’t need to cost you a fortune! Depending on what you’re looking for and the anatomy of your small business, a VoIP phone system can cost anywhere from £6 per user, per month all the way up to £135 per user, per month. The choices we look at closely in this review, however, range from £12.50 to £20 per user, per month. How do I set up a small business phone system? Setting up a small business phone system isn’t meant to be hard. Overall, there are four steps that you need to follow to have a fully operational VoIP phone system:Choose a provider that works for you and suits your small business needs, and activate your account based on the specific instructions you’re given.Set up IP phones: if you choose to use IP desk phones, you’ll next need to set these up. It’s as easy as attaching your handset to the base of your IP phone using the cord provided. Plug your ethernet cable into your phone’s WAN port, and the other end into your router. As a side note, keep in mind you don’t need a desk phone if you are installing a VoIP system – you can still access and use on devices including smartphones, tablets, and computers.Transfer your existing toll-free number: if you have an existing toll-free phone number, you can port this into your new business phone system.Customise your phone system: every business is different, so there’ll naturally be features that you’ll prioritise above others. As an administrator, you can change and set up business phone system settings and assign users and extensions based on their job description. Traditional PBX vs. VoIP: what’s the difference? The long and the short of it is this: a traditional PBX system uses the landline to make and receive calls, while a VoIP system uses the internet.Both phone systems allow you to receive multiple calls at the same time, but while a PBX uses a digital on-premise switchboard to branch calls off to different handsets, a VoIP system uses an online server. Let's take a closer look:VoIP phone systemsVoIP phone systems work by transmitting phone audio over the internet. They come in two varieties: on-premise VoIP, and hosted VoIP (also known as cloud-based VoIP).With on-premise VoIP, the system is hosted on your own servers. You'll need all the right hardware for this, and you'll need to pay someone with the right expertise to build and maintain the system.By contrast, a hosted VoIP system lives on your system supplier's servers, and is managed and maintained by your supplier, not you. Over and above all other kinds of phone system, we recommend hosted VoIP to small businesses. This is because it's affordable, it's easy to install, and it tends to come with sophisticated call and UC features for your team to benefit from. That's why most of the systems we review on this page are cloud-based VoIP systems.Another benefit of a VoIP system is that it can be accessed from anywhere. Most come with an app that your team can download onto a device of their choice, and use to make calls and access the system features – meaning you don't even need to buy desk phones if you're on a budget. If you do choose to, though, you should look for IP phones: these are VoIP-compatible desk phones.Traditional phone systemsIf you're not ready to upgrade to VoIP, a traditional landline phone system may be suitable for very small businesses with a handful of employees. All you need is one line in and a couple of phones, so that more than one employee can pick up the phone if it rings.If you tend to receive lots of calls, having one phone line could be holding you back. This is where a PBX system comes in.A PBX phone system turns your traditional phone system into a multi-line system by giving you the option of adding extensions that lead to each phone. Once a call comes in, the PBX auto attendant directs the caller to the right extension number, freeing up the phone line for another call to come in.The features of a landline PBX phone system are basic compared to those available with VoIP – which is one of the reasons why we recommend VoIP instead – but you'll still be able to coordinate incoming and outgoing calls, make call transfers, and manage voicemail.Of course, PBX is flexible in the sense that it can be used with VoIP as well as the landline. In fact, many suppliers give you the option to create an IP PBX system. This uses SIP trunking to connect a traditional phone system to the internet, meaning you can make calls over the internet and benefit from VoIP functionality, in addition to making calls using the traditional landline. How many phone lines do I need for my business? If you choose a VoIP system, you can run multiple phone lines over one internet connection which can easily be scaled up or down depending on your needs.
