Finding the right office phone system for your small business is important decision if you’re looking to compete with larger, more established competitors. A comprehensive phone system for any organization should include a range of functions which not only support the way in which your business communicates with customers and clients but also internally across divisional teams and departments.


Voice over Internet Protocol – also called VoIP and IP telephony – is fast becoming a business standard all over the world. It allows voice, video, and oftentimes collaborative interactivity without using dedicated phone lines, and is often less expensive than traditional telephone services. Granted, VoIP is a clear choice for many businesses, but how do you choose the best VoIP phone system for your small business?

What Benefits Are You Looking For In a Phone System?


How to Choose a Small Business Phone System

Finding an office VoIP phone solution to suit your business needs is made slightly more challenging with the sheer amount of choice you’re faced with. However, this is also an advantage as well, with a number of leading manufacturers within the telecoms industry now focusing their efforts on IP phones you can be sure to find a solution that meets your budget and includes features most beneficial for your business.

Our team of experts have carefully surveyed the best VoIP phones available from leading suppliers including Polycom, Mitel, Avaya, Cisco and more to bring you a selection of the very best office phones that are ideal for small to medium-sized businesses, catering for a broad range of budget options.

Many VoIP providers recommend particular models of desktop phones that are known to work optimally with their services. The larger providers also often supply office phone handsets as part of your chosen package, either for a single up-front payment or as an on going monthly contract.

Whether you are looking to install a new system or upgrade your network, there are a number of considerations you need to make when deciding on a phone system for your small business.

These factors can be broken down into the following:

  • How many business phone lines do you require?
  • How many extensions are needed for the size of your office?
  • What telephone system features would most benefit your business
  • How will your businesses’s growth strategy impact your phone system needs in the future

This guide will explore a range of the best office phone systems for small business, providing a breakdown of the different type of solutions to ensure you can make an informed decision regardless of the size of your business or the industry you operate within.

The Different Types of Office Phone Systems

Unfortunately, there is no ‘one best office phone system for everyone’. Different types of organizations have different priorities and budgets, and even two nearly identical organizations might face vastly different challenges and opportunities. With that in mind let’s look at which systems perform better for different customers.

PSTN (Landline) Phone Systems

These are the ‘standard’ phone systems most of us grew up with. Only fairly recently have other types been commercially available, so these are what many think of as ‘normal’ phones. PSTN stands for Publicly Switched Telephone Network.

Pros:

 These are a very mature technology, so they are reliable.
 Most users already understand the system.

Cons:

 In order to use these for any but the smallest offices, you will need to have PBX or VoIP-type extension hardware installed on-site.
 Many providers are getting out of the ‘landline’ business, so these systems could soon become difficult to purchase and service.
 Long distance calls are particularly expensive over most PSTN systems.

VoIP (Voice over Internet Protocol) Phone Systems

These systems route your voice traffic over your existing internet connection. They do not require Traditional PBX (Private Branch Exchange) hardware, but the features and details can vary significantly between providers and systems.

Pros:

 VoIP is by now also a well-established system with excellent reliability.
 These systems offer a wide variety of standard features that were added extras on PSTN systems.
 They are inexpensive, especially as most do not apply any long-distance surcharge.
 It is particularly easy to route calls to remote employees, or those who are traveling.

Cons:

 These systems rely totally on your internet connection, so if that ever goes down (which still happens to the best networks) your organization could be completely cut off.

Different Types of VoIP Phones

Once you have all of the necessary components in place to build your VoIP system, it is worth looking at the different types of phones available for businesses. There are three main types of VoIP phone; wireless, soft and conferencing.

Wireless – A VoIP phone with built in Wi-Fi or a DECT transceiver which connects to a base station or access point. Cordless phones allows users to move freely around their workspace while on a call.

Softphones – This is in essence a software application which is installed onto a computer and equips the device with the ability to make and receive calls. Softphones are particularly useful for remote workers and even call centers because they are relatively cheap to set up and run.

Conferencing – A conference phone will usually function in the same way as an analogue telephone. However an IP conferencing phone will be used in a large business or conferencing facility where calls take place with multiple participants

With so many options available, VoIP offers a workable and practical solution for many businesses and contact centers who need a fast, reliable and high quality communications system.

VoIP Solutions for Small Business

Small business owners can often have trouble building a strong reputation and one of the main reasons for this is because it is sometimes difficult persuading a potential customer that you can meet their requirements. Voice Over Internet Protocol systems allow businesses to appear more professional. Modern VoIP solutions offer a virtual receptionist, video conferencing, call recording, screening and other tools which businesses can make use of.

VoIP can give the impression of a larger business than it actually is, which can give customers more confidence. As an example, a caller may find it more professional to receive an automated line with a range of options to be put through to the right person than simply receive an immediate answer by a member of the team. VoIP can also create the impression that your business is well established and properly set up with wider coverage than perhaps a small local area.

Cost of Modern Office Phone Systems

There are a wide range of potential costs and charges associated with setting up any office phone system. Some of these costs will only be applicable for on-premise systems, and will also depend on your existing network infrastructure and phone equipment:

  • Cost of IP-PBX central unit and network converters
  • Cost of installation 
  • Cost of handsets, headsets and associated peripherals
  • Cost of maintenance
  • Cost of employee training
  • Cost of additional features and service options: international call support etc.

The cost of the IP-PBX and related hardware can vary greatly, from as little as $80 up to several thousand for fully-fledged units with support for SIP trunking and advanced features.

Handsets also vary greatly in price, from as little as $20 for basic models, to around $100 for mid-range business IP phones, to over $500 for more advanced units with video capabilities and other features. Quite often businesses will invest in one or two more advanced models for senior managers and the person who will be administrating the phone system for things like conference calls, and buy cheaper standard models for the majority of desks.

Service providers will also often bundle preferred models of handsets with their solutions, in which case you may be able to save by purchasing or renting such equipment as part of an overall package. It’s still a good idea to be aware of the regular price of the equipment you’re looking at though, so you know if you’re getting a good deal on a bundled solution.

A typical metric used to compare the suitability of different phone systems for businesses with varying requirements is known as Total Cost of Ownership (TCO). These figures can be plotted on a graph for hosted and on-premises phone systems, illustrating the essential threshold above or below  which it is more cost-effective to invest in one or the other, based on how much you are spending per year and how many years you anticipate using this system:

TCO-hosted-vs-premise-chart

In beginning to calculate the anticipated costs, you will inevitably begin to acquaint yourself with a few of the leading service providers in order to gather their pricing information. Our next step will be to look in more depth at the providers themselves and the broader service and support solutions they can deliver beyond costs for individual equipment items.

Additional Purchasing Tips

 Think scalability: It’s important to invest in a phone system that can grow with your business. Ensure that the system you choose can be easily upgraded to handle greater volumes of incoming and outgoing calls, without having to go through the process again of getting a whole new system.

 Budget for unexpected maintenance: It can be difficult to account for all the possible costs and overheads associated with a new phone system installation, but you should keep a contingency fund available if possible for those unexpected fixes and bumps in the first few months of getting the system up and running.

 Focus on the options you need: It’s quite easy to be dazzled by the range and novelty value of some of the features available when first appraising your phone system options. Know which are the features that are essential or could add massive value to your business, and which are appealing but not absolutely essential. If a key feature on your wants list is not included as standard, see if the provider can add it, and there are features included that you know are of limited value to you, see if they can removed to reduce the overall cost. Modern VoIP phone solutions have never been so flexible and customisable, so take advantage of this.

 Training: Check with your prospective service providers whether training for your employees and phone system users is included, whether this is also applicable for new employees who join the business after the phone system is set up, and in what form the training comes – is it a video series or in-person live workshops, for example.


How Does a VoIP Phone Work?

A VoIP or IP phone system routes your calls, voice messaging, SMS traffic and even faxes over either the public internet or a private data network rather than the standard telephone system. Most business users are attracted to VoIP solutions as a way of avoiding long-distance telephone charges.

When you use a VoIP phone system, your voice is digitized into packets of information that the internet can route to the recipient, which might be another VoIP user or your VoIP service provider’s interface with the public telephone network. This allows VoIP users to contact standard and mobile telephone users seamlessly.


Business VoIP Phone System Diagram


There are many different methods used to achieve this, however. For example, the system might use a ‘codec’ – a way of encoding audio or video signals – which is optimized for narrow bandwidths, for higher security, or for near-flawless audio clarity. Some systems can even choose which codec to use based on network performance and other factors.

Some ‘first generation’ VoIP solutions are modeled after the older phone network in order to offer fully compatible services. Other, ‘second generation’ VoIP providers like Skype provide free or nearly free traffic over a closed network of registered users. Still other, ‘third generation’ providers use a ‘federated VoIP’ system to allow dynamic connectivity between internet domains.

In terms of style and design a VoIP phone is made up up many of the same components as a typical desk phone. Advanced functions which will be explored in more detail below may include large touch screens and additional Ethernet ports.


VoIP Phone Benefits

Cost Savings

If you are looking for a phone system for your business you no doubt already know that finding the right system at the right price can be a difficult task. Phone systems can be a costly investment but one benefit of VoIP phone systems is that they allow you to save some of this expense by eliminating setup and installation fees as well as preventing the need for any on premise server equipment and maintenance.

Sound Quality

Gone are the days when VoIP technology could not match the voice clarity of traditional phone networks. Today you can make calls anywhere in the world and no longer be able to notice any difference at all with a significant improvement in the call quality and a decrease in the number of dropped calls meaning no more strained business relations and more satisfied customers.

Flexibility

The virtual nature of VoIP mean you no longer have to deal with the hassle of registering and setting up country specific phone numbers, instead you can ensure you can be reached on the same business number wherever you are. This is vitally important for any business owners who are required to travel for meetings and other appointments and may be worried about picking up calls on the move.

Advanced Functionality

As with any organization, even with a team smaller in size the output and productivity levels must still remain high if an organization is to grow and hit KPIs. This means it is even more important that the phone system you choose has features that help your staff in as many ways as possible and additional features of VoIP phones such as unified video and voice functionality and customizable touch-screen displays can be vitally important.


Key Features of VoIP Office Phones

As well as the convenience and cost-saving benefits of converging your telephone and Internet systems onto one network, VoIP also brings access to the kind of advanced phone service features that until a few years ago only large corporations could have afforded with a traditional telephone system.

Business VoIP systems provide a great degree of customization, allowing you to piece together just the features you want or need for your particular requirements – without having to pay for bundled features that you aren’t going to use.

 Advanced voicemail / Click to call
The difference between the old-school answering machine and VoIP-enhanced voicemail perfectly illustrates how VoIP systems take conventional telephony concepts and bring a whole new level of flexibility and efficiency to their implementation. With VoIP voicemail, you’re never more than a click away from calling someone back directly and easily – but you might also prefer to get each voicemail emailed to you as an audio file attachment, or automatically transcribed and delivered to you via text message or email. You also have the option of tracking missed calls from your email, and calling them back directly from within your email interface: a feature known as ‘click to call’. You can even incorporate fax into the equation, sending and receiving ‘virtual faxes’ as PDFs.


 Online dashboard
From this software interface you have immediate access and control over every aspect of your business phone system, such as voicemail, call logs, contacts databases, programming greetings and messages, setting up conference calls and directing traffic. From here those employees set up as administrators can also manage billing and further customisation of the phone system as needed.


 Find me/follow me
 With VoIP you can assign each employee or member of the team a single ‘virtual extension’ number rather than everyone needing a separate number for each location. Calls to a virtual extension can then be set to ring all of your phones simultaneously, or in order, and also how to handle a missed call. You can choose if a call should go to voicemail or be passed to another extension. The virtual extension also works on outgoing calls, so whichever phone device you’re actually calling from or where you are, the receiving caller ID will show your number and you can present a consistent front to clients, suppliers and customers.

 Auto Attendant
Also sometimes called a digital or virtual receptionist, an auto-attendant is a voice menu system that greets and guides callers through numbered options so that they can be transferred to the relevant departments or extensions within the company.

 Interactive Voice Response (IVR)
Callers are greeted by an automated voice which presents them with a number of options – they can then interact with the voice, selecting their preferred option (for example, which department they would like to speak to) using the keypad on their phone. IVR systems can handle high volumes of incoming calls, and can reduce costs and improve customer experiences by providing access to information and services 24 hours a day without the need for human staffing around the clock.


 Automatic Call Distribution (ACD)
Related to the hunt group or line hunt feature in traditional PBX telephony, ACD is popular with businesses receiving high volumes of incoming calls. The ACD system distributes incoming calls amongst a specific group of phone terminals or operators based on particular criteria such as the customers selection, their phone number, the selected incoming line to the system, or the time of day the call was processed.


 Barge-In
Allows a user to enter a call  between two other extensions or between an internal extension and an outside line, either creating a three-way call or simply monitoring (listening in on) active calls. The feature can be set up to sound a warning tone to the other users when a barge-in is about to take place.


 Call Me Now
This feature allows customers to call your business directly from a form or contact page of your company website, making customer communications fast and easy.


 Call Recording
Users have the option to record, playback, download and delete any incoming or outgoing calls. This feature is often implemented on an individual extension basis, so you make this a system-wide feature or you can choose which phones or extension users have access to the record functions.


 Day/Night Mode
Allows users to set different sets of rules for how their business phone system functions or routes calls depending on whether incoming calls are received during business hours (day) or after hours when no-one is in the around (night).  Night mode typically serves as an ‘autopilot’ mode until the day mode is restored the following morning.


 Conference Bridge
This feature enables users to set up virtual meeting rooms, which can then be joined by participants on their own devices. Most service plans will allow access for 15-25 participants as standard.


 Video Conferencing
Going even further than conference calling, video conference calling works the same way, but also presents all parties with a picture (live video) of the other callers.


 5 Ways to Improve Call Quality

There are innumerable ‘tips and tricks’ to getting the most out of nay service, but following these 5 pieces of advice should put you well on your way to the best call quality VoIP technology can provide:

  • Use a private, dedicated network rather than the internet for your internal calls. This provides more bandwidth and is also more secure.
  • If you do use public internet, use a VLAN and the right switching equipment to keep data and voice traffic separate.
  • Select or enable your provider’s network monitoring service. This will help eliminate packet loss and the ‘jittery’ sound quality it can produce.
  • Chose equipment that supports ‘echo cancellation’ to eliminate one of the most common audio artefacts of older VoIP systems.
  • Make sure your network has adequate bandwidth for your expected call volume, especially at peak times. You might even consider upgrading your network to allow for better sound quality.

VoIP systems regularly rank among the best business phone systems because of their low cost, flexibility and added features relative to traditional telephone systems. Now that you know a bit more about how they work and how to choose the best VoIP phones for you, you’re well on your way to making the most of this still relatively new technology.
