Tips for choosing the best provider for you

While every business’ needs are different, and so what you’ll look for in a phone systems provider will change, here are some questions to consider to help you navigate the decision-making process.

  • Specialism – Do you want a provider that specialises in phones for businesses or would a more generalist supplier be more suitable?
  • Customer support – Where and how can you access assistance? Think about the time zone that support agents are located in, and the ways in which you can contact them e.g. phone, email, live chat
  • Services – Is it only the actual devices that your business requires, or are you looking for a provider that can offer additional services, like hosting, as well?
  • Purpose – If you need phones that can offer specific functions, then seek out a provider that offers these in their devices, such as connectivity or compatibility with other systems
  • Budget – the amount of funds that you can allocate for the phone system is likely to affect which providers you can choose from, as they all have a different price points

Tips for choosing the best business phone for you

There’s a lot to consider when deciding which business telephone system is best for your startup. We outline some of the key questions below:

  • What features will work for you? – Most small businesses don’t have the luxury of IT departments to help with their technological woes. Maybe your business has complicated needs, or perhaps it makes sense to keep things simple.
  • What is your current setup? – Because VoIP requires less equipment and installation, it often helps businesses cut costs. But of course, this can depend on the current infrastructure of where you work. You could already be set up with PBX.
  • Are you growing? – Traditionally, PBX systems come with specific telephones. This could mean that to change the phone system, you would need to buy all new equipment too. But not always – be sure to check with the provider.
  • How is your internet quality? – Since VoIP systems run over the internet, even distance calls can be crystal clear. But if you live in an area where the signal is poor or unreliable, PBX may offer the most peace of mind.
  • How mobile are you? – If you or your staff spend a lot of time working remotely, hosted (or cloud) phone providers will help to keep you connected.
  • What type of calls does your business make? For example, consider if your business makes predominantly local, national or international calls. Similarly, assess if they’re mainly inbound or outbound calls, as well as other types.
  • Where will your phones be located? For example, reception phones that handle multiple calls and desk phones for a single staff member will have different requirements because of their location.
  • What type of phone system will your business use? This could be a landline, a multi-line system or business mobiles. It may be a combination of these types, or all three.

  • Provide top customer service – Be there when your customers need you. Did you know calls are also the most effective method for closing sales? And for unique queries or complaints, nothing works wonders more than speaking to a real person.

Small business telephone systems: The FAQs

We’ve profiled some of the best phone systems and providers to help you choose the right ones for your startup. But what if you still have some questions? Here we highlight some of the main queries.

What is the difference between VoIP and SIP?

SIP stands for Session Initiation Protocol and is the line type for connecting Voice over Internet Protocol (VoIP) to a phone system – allowing video and voice calls to be made over the internet.

  • Although VoIP and SIP both support IP (or internet-based) calls, they aren’t the same thing.
  • VoIP simply means making calls over the internet.
  • SIP, on the other hand, has a much larger scope. It’s a specific protocol that’s used to enable a range of multimedia sessions, which include VoIP calls.

What is PBX?

PBX stands for Private Branch Exchange. This means:

  • You can use outside lines for making external calls
  • Your internal telephone numbers can also be connected to a public telephone network or VoIP provider.
  • PBX phone systems are increasingly similar to VoIP phones. They often have IP points added, so you can host the phone system for your business within the cloud.

Which features do business telephone systems need?

Think about what your budget is and what your small business requires from a phone system. Some features to consider include:

  • Automated call forwarding – Automatically transfer calls to your business phone to a different number at any location. This can be very useful if you’re expecting an important call to your business, but are out of the office or even on holiday.
  • Dashboard – This allows you to manage your office telephone system from one central resource or programme, with access for all team members, dependant on what their needs are. Some dashboards also allow you to integrate all your communication channels, so you have control over your voicemails, emails, SMS and fax messages, at one touch point.
  • Speed-dialling – Store the numbers your team members call the most frequently and easily call them with a one-button dial.
  • Answering machine – This may be a standard answer machine system. Or your business might require the ability to convert voicemails into a readable email that gets sent straight to your inbox. It allows you to sort and scan through missed calls and voicemails at a quicker rate than simply listening to each message individually.
  • Conference calling – This feature enables your team to speak to people off-site easily. Conference calls can be popular for team meetings with off-site staff members or for calls between your sales team and relevant clients, for example.
  • Video calls – If you work remotely, or want to speak to suppliers and providers without the expense of arranging an in-person meeting, a business phone system with a video calling feature is ideal.

The most basic telephone systems will tend to focus on the most common needs (like speed-dialling and an easy-to-use dashboard), whilst more sophisticated models may be able to do everything on the list.
