Top 10 Features to Look for When Implementing a Business VoIP Solution

Back in 2015 we looked at this conundrum as to what were the best features to look for in a virtual telephone system. Needless to say in 2020, and six years on those key features are no less important but other features have arisen that are now hugely important to the small medium business.

The difference today from back in 2015 is that communications has changed. Where once there was simply voice and chat now a whole array of communication channels need to be supported. These include, voice, chat, instant messaging, SMS, email, video, and video/audio conferencing.

Indeed the need for Omni-channel support is now the priority when selecting a virtual telephone system as businesses must now support the communication channels of preference for their customers.

As a result we have to consider that since 2015 there have been changes in what are now considered required features. However, we should not just forget what once some attractive features were in a small business virtual PBX system but consider them as being now basic features

When considering a business class VoIP system one of the first conundrums to consider is what features and functions are required considering that each vendor offers a myriad of functions and feature options. Indeed so comprehensive are some vendors feature packs that it can be a challenge just to make sense of them, and what benefits they might bring to the business. Moreover, some features are essential whilst others are highly specialized and only of use under specific circumstances. Subsequently, it has become difficult for IT and the VoIP stakeholders to differentiate, validate and justify the functions and features that are required and those that would be nice to have. For example, some of the high-end hosted IP PBX systems have extensive call center features, but those are overkill for an SMB with no contact center facility. Alternatively, an SMB with extensive customer care and technical support might not need a fully featured contact center but might benefit from some of those features such as advanced queuing and CRM / Outlook integration.

Therefore, because requirement differ from one organization to another even in the same vertical market space, in this article we will look at what features you really must have for a balanced business solution that will cover the requirements of typical startups, SMB and larger organizations.

Previously we rated back in 2015 the top essential features as being:

The 10 Essential Features 2015:

  1. Extension Dialing
  2. Auto Attendant/Receptionist
  3. Voicemail to email
  4. Advanced Call Queuing
  5. Advanced Call Forwarding
  6. Web-based Administration
  7. Music on hold
  8. Voice and Video Conferencing
  9. CRM integration
  10. Call Screening

1. Extension Dialing

VoIP extension dialing allows employees to call other employees wherever they are located using the internal local extension number – usually a four digit number. Extension dialing makes call transfer faster and more efficient and can make multiple work locations, such as employee’s homes, remote offices, mobile workers, even employees in other countries, all appear as if they are working within a single location.

2. Auto Attendant Receptionist

An auto-attendant come receptionist uses IVR to greet callers and offer them a menu of options, such as ‘Press 1, for Sales,’ etc. This feature provides the business with an enhanced professional image and reflects well with first time callers, as the image projected is that of a large organization. This feature is especially useful for startups and SMBs where there is no ‘real’ receptionist and the VoIP system handles incoming calls via call forwarding.

3. Voicemail to email

Another very useful feature for business is sending voice messages to email – either as MP3 sound files or by having voice messages automatically transcribed to text. The advantages of sending voicemail to email in text format is that messages is that the recipient can be check their messages silently in meetings or presentations without causing any disruption. Moreover having all your messages in one location, email, means you are less likely to miss any important messages.

4. Advanced Call Queuing

Call queuing is a desirable feature for businesses that use group extensions, for example an extension for the sales or service departments. In situations such as this, it is important that if all the sales or support agents are busy on calls that other incoming calls do not go unanswered. Instead, these calls will be queued and managed by the system, by providing on-hold music, and by keeping the caller informed of their call status, wait time and position in the queue.

5. Advanced Call Forwarding

Businesses today are heavily reliant on mobile employees working from home or their mobile phones. This is especially true now that BYOD (Bring Your Own Device) has become an accepted business practice. Employees’ no longer wish to be tied to a desk phone, furthermore that is not efficient business practice, employees’ need to be mobile but contactable via the organizations phone system. Advanced call forwarding facilitates this as the VoIP system can forward calls to any phone such as a home landline, a mobile phone or a desk phone in a client’s office. This ability for the VoIP system to find the employee by calling a configured list of phone numbers either sequentially or simultaneously provides employees with the freedom of mobility to do their job yet still remain contactable, as if they were on their desk extension.

6. Web-based Administration

One of the advantages of hosted cloud based VoIP systems is that they facilitate secure web administration of the VoIP system. This is very important for efficient administration and management of the VoIP system. An administrator can create, edited, or delete an extension from any internet capable device and from any location. Furthermore, administrators have the freedom to run, compile and deliver reports by email to stakeholders at anytime and from any device or location.

7. Music on Hold

This is an old feature but still an important one. However, with modern VoIP systems administrators should look for the ability to select custom music to play when callers are on hold. Most systems allow for custom music though some have strict copyright restrictions.

8. Voice and Web Conferencing

Not so long ago, voice and video conferencing was only available to very large organizations. However, VoIP technology has brought voice and video conferencing to the startup and SMB. Moreover, conferencing is now considered a vital business tool that can improve efficiency and reduce wasted time, for example, the time spent traveling to meetings. Furthermore, voice and video conferencing although in many cases considered an extra is still cheap and simple to implement and operate. However, this feature creates value and opportunity beyond hosting remote virtual meetings it has tremendous capabilities for supporting remote team collaboration, presentations and distant learning training programs.

9. CRM and Business Application Integration

Another feature that was once only available to big organizations is the integration of business applications with the phone system. With VoIP, this is now possible as both applications run on IP so are readily integrated. Although CRM and business applications is often an advanced feature it can be highly productive and of great value to the business. The VoIP system can identify incoming callers and pop up their customer history record onto the agents screen allowing the agent to have all relevant information at hand whilst they are on the call. Applications such as CRM, Outlook and Billing systems are routinely integrated, greatly enhancing business efficiency and productivity.

10. Call Screening

The ability to screen incoming calls is another necessary business feature as it allows the employee to make decisions on how they will handle the call. For example, if the caller is a friend or relative they may wish to divert the call to their mobile phone. Call screening can be accomplished in several ways from simply displaying the caller ID on the employees phone display, to more complex methods such as looking up and identifying the caller via a database and whispering the name prior to the call being connected – all this is transparent to the caller. Call screening is a necessary feature in business systems as cold calling, and persistent and aggressive marketing from vendors can be a serious waste of time and patience.

However, in 2020 times have changed and most of the features are in-built to the system but other features such as multi-channel support and collaboration are more desirable – so here are 5 bonus features to keep an eye open for:

5 additional Value-Add Features

Omnichannel Support

This is the requirement to support voice, video, email, SMS, chat and video as a necessity as one has to support the channels that customers prefer. It is now necessary to support all customer channels and integrate them within a single system. The importance is that  customers may want to communicate with you through email, or voice or perhaps even through IM or SMS, regardless you need to be able to support those diverse channels.

Website Integration

These are buttons that can be integrated within a website that allow customers to initiate a call to the company to find out more information or to make an order. These widgets are typically plugins for your website that will initiate a call, a live chat or post a form.

Desktop Sharing

The ability to share your screen or desktop is a huge benefit to SMB as it allows you to share and collaborate with team members. It also allows you to conduct distance training or presentations as the instructor can share their screen with the students.

Mobile Apps

This is probably one of the most important advancements as it allows people to work from their mobile phones. Instead of being tied to the office employees can go out and about and have business calls forwarded to their mobile phones.


This is now a major feature of every virtual PBX as it allows a user to be contacted regardless of where they may be. The phone system rings each configured device either in sequence (call hunt) or all together (call blast) to ensure that you never miss an important call. Read more.


These are the top additional features, which you should seriously lookout for Today. I would strongly recommend any generic VoIP business phone system should support the initial top ten features at a minimum and then recommend looking at getting the bonus features as well as these are become de-facto requirements in modern communications... Some may be more important to your business that others, but if you consider future business growth then most of these features will prove to be advantageous and of value to a business regardless of their size.
