What are the benefits of a VoIP Phone Solution for Small Businesses?


Reduced expenditure. VoIP systems are cheaper when compared to traditional business phone systems such as a PBX (see our article on PBX here). The reason for this is if you work in an office where you make internal calls you are likely to accumulate a lot of internal call charges. Across a large company, internal call charges can be eye-watering. Transitioning to a business VoIP system removes the internal call charges entirely as calls are made through your internet connection.


Another added advantage but not necessarily one that may be applicable is that VoIP telephone providers often bundle in free-to-dial codes. Such as free calls to 01 or 08 numbers. Telecom providers also sometimes offer this, so it is best to compare tariffs to understand if there is any saving here.


More functionality. Depending on your existing business phone system the difference in functionality could be staggering. Some PBX systems are features rich so again it is important to compare the two side by side. That being said, VoIP phone providers offer great features on their business VoIP systems often at no additional cost. Regulated businesses need call recordings more often than not nowadays and VoIP systems have the added benefit of being able to integrate with a business’s CRM to log/records calls as required.


VoIP telephone systems also have added call management features, such as call queues, diversion, and statistics. Business VoIP system features give your staff more accountability. Ever wondered if a customer service agent is deliberately terminating calls? VoIP will tell you in no uncertain terms what you need to know when you need to know it.


As mentioned most UK business VoIP providers will work with you to integrate the VoIP system into your CRM. This enables businesses to improve call management and efficiency whilst keeping customer details updated. VoIP gives your business a simplicity that traditional phone systems lack. It seamlessly fits into your existing business structure (at least it should do as the capability is there).


VoIP phone systems for small businesses can be scaled back and grow in relation to your business. It lacks the traditional limitations of a phone system which means if you’re anticipating rapid growth your VoIP system is inherently able to cope. Need a new user added? Or 10? VoIP allows you to do this so that your new staff can hit the ground running.


For fast-growing companies or high staff turnover businesses, VoIP is a robust and straightforward system that offers the flexibility and the customization you need, when you need it most.


What isn’t so great about VoIP systems?

There are a couple of things to be mindful of. The last one is significant and is the bugbear of VoIP clients all over the country.


Dependency on Internet Connection and adequate bandwidth. This is the bugbear we mentioned. Most businesses trade with a few internet outages during the year in the UK. Normally on traditional phone line systems, this would not hamper your progress, your phones still ring, and your sales agents are still able to pick up the phone and make the next sale. With VoIP, if the internet connection drops then your entire phone functionality goes with it. If you know your internet connection drops out frequently it is worth upgrading your connection or if that is not possible consider a traditional telephone system over VoIP until you have a reliable internet supplier.


Bandwidth is also a common issue, VoIP is data intensive and takes up bandwidth, if you rely on fast connections you must ensure your existing bandwidth is able to cope with the increased workload.


It is of vital importance you upgrade your internet connection as much as possible to ensure your VoIP phone system improves your business rather than present it with unwanted hurdles.


There are many factors to consider before choosing your VoIP phone system for your business. What is the size of your business? What you are looking to achieve with your business VoIP system? How much you are willing to spend? Are you looking for the cheapest VoIP system or have a bigger budget to spend? Below we look at the features and services of the top 10 UK VoIP providers of 2019.


Does the VoIP provider offer flexible, scalable service?

Using your VoIP service requires a working internet connection. One of the things that are important to consider when choosing between UK VoIP providers is the degree of flexibility and scalability they offer.


For example, do they offer IP service as part of the VoIP package? If so, this can save you quite a bit versus using a separate provider. Do they offer any other services you are already paying another provider for or services you may consider picking up in the near future? Look for things like collaboration and remote working options, if these would be of any use to your organisation. Another huge benefit that VoIP providers offer is the inclusion of IP desk phones within certain packages so this is something else to look out for.


Scalability is another issue. Most providers will happily increase the number of units or services they provide you under contract, but some will refuse to reduce your agreement (and the fees associated with it) until your contract has expired.


Speed is another huge consideration for modern businesses. Just as you need internet speed can make a massive difference to the efficiency and productivity of a workforce, so can your VoIP phone speeds.


How financially stable is this VoIP provider?

One of the things you will want to research about UK VoIP providers before selecting one is their financial state and their business history. Have they been in business long? What do their debt and profitability situations look like? Are they a ‘plucky new start-up’ or a ‘dependable industry titan’?


Another thing to consider is their commitment to staying on the cutting edge of evolving technology. Will they offer upgrades to their service and equipment quickly enough to satisfy your needs?


After all, getting an amazing deal won’t do you much good if they go out of business in 6 months or are unable to offer the latest upgrades. In fact, having to suddenly seek out a new provider and new equipment could cost you a great deal, both financially and in terms of customer confidence. It never looks good when your phones get disconnected so thoroughly researching your provider is a must if you want to future-proof your business.


Do they offer on-premise, hosted service, or both?

This is where it pays to know what is right for your business. VoIP providers who offer hosted VoIP services typically charge little or nothing up front, but their monthly, quarterly, or yearly fees sooner or later add up quite a bit. On the plus side, they tend to be very scalable, and take care of their own IT support, equipment upgrades, and other ancillary issues, which can often save organisations without their own extensive IT resources quite a lot.


On the other hand, on-premise VoIP service providers typically only ensure that your connection to the outside world is up and running. You have to maintain (and often purchase or lease) your own equipment, including the server that handles all your VoIP traffic. This tends to cost a lot more than hosted VoIP services up front, but the ongoing fees are typically much lower. In the long run, on-premise VoIP services tend to cost less, especially for larger organisations.


What is the total cost of ownership (TCO) for the system(s) they provide?

Make sure you are looking at the full, real costs (the TCO) of the system you select. The best VoIP providers in the UK can give you TCO figures, which should include the costs of training, upgrades, personnel requirements, and upgrades predicted for a period of several years. These can be a great deal higher than the quoted price of the system so well worth considering before rushing to invest in a modern phone system.


What disaster recovery provisions does the provider have in place?

Say you elect to use a hosted VoIP service provider. What will happen if a flood or fire wipes out their data centre, or if they are hacked? Do they have reliable, redundant backup systems and top-of-the-line security in place? If not, that ‘good deal’ might cost you more than you think.


How deep is their SLA (Service Level Agreement)?

Read all of the small print and try to speak with some of the provider’s existing and past customers. What is their contractual obligation when something goes wrong, and do they live up to that agreement in practice?


The best VoIP providers UK-wide will often exceed their SLAs, so keep that in mind as well.


How invested is the provider in their technology and support capacity?

Ignoring the brochures, commercials, and inevitable claims of being the ‘best VoIP service in the UK’, can the provider demonstrate a real commitment to staying on the cutting edge of the technology, and backing that up with effective customer support?


There you have it, by now you should feel empowered to decide with confidence whether or not VoIP is the best phone system for your business. Beyond that, you should also be well-versed on what steps to take and how best to implement VoIP into your business. It is always important to spend the day comparing providers, make a list of their benefits and weigh up which provider will best fit your business model. You will likely be surprised at the packages available from providers especially if they know you are VoIP savvy and shopping around for a provider. The best thing to do is to let them give you multiple reasons to choose them.
