Introduction to Business VoIP

Chances are, you already use some form of VoIP or internet phone service through your business phone line. If you’ve ever used Skype or WhatsApp, or any kind of Internet phone to make a call, you’re experiencing the power of Voice Over IP, or to put it simply making calls over the internet. When it comes to integrating VoIP into your business line, there are some factors to consider before you choose a provider. The top VoIP providers can help you lower costs, reach more customers, and even enhance your mobility and productivity. The wrong VoIP companies could be too expensive for you or simply not understand the importance of this tool in your business.

Benefits of Having a Business VoIP Phone System

The full benefits of having a business phone system will depend on the size and type of business you own. However, loosely speaking, many business benefits from:

Lower Costs - Businesses on average see a reduction in costs of between 50% and 75% after switching to VoIP. This is a combination of reduced communication expenses and logistical benefits.

Productivity - Investing in internet phone allows companies to let their employees work remotely, which can increase productivity by almost 20%. Also, employees will be able to reach each other more easily, thus saving time.

Reliability - Because of QoS (Quality of service) protocols, common issues like jitter, latency or delay are monitored for a satisfactory standard for business practice. In a recent study, less than 0.5% of survey respondents reported being dissatisfied with VoIP call quality.

Customer Satisfaction - Unsatisfied customers would rather switch services than complain, so customer service needs to be more on top of visitors needs than ever before. Giving your customers more ways to reach your business is simple with the help of VoIP. This could be helping employees work remotely, increasing ‘office hours’ or just offering the customers a number to call when a problem arises.

VoIP Features

Voice over IP companies will differ greatly from one to the next. Some of the most popular features are:

  • Call routing

  • Call recording

  • Migration of your current numbers

  • Voicemail transcription

  • Software phone

  • 24/7 tech support

  • SIP phone support

  • Toll-free options

  • Speed dial

  • SMS messaging

  • E911 services

  • Group calling

  • Video conferencing

  • Voicemail to email

Types of VoIP Systems

The biggest difference in costs is going to be dependent on the type of VoIP service you choose for your business. There are three main types of VoIP systems available:

Hosted System. Similar to a website hosting plan, this means that the vendor owns the hardware, and your business leases or buys the phones. Maintenance will be handled by the vendor, too. Companies will usually charge a subscription to use the internet business phone system. This includes lower costs up-front, and no maintenance, so it works well for businesses without their own IT staff. However, it is less customizable and reliant on the vendor’s servers.

On-Premise System. In this scenario, your business owns the hardware, and that means that you are responsible for any upgrades or maintenance work. You’ll of course have a higher initial cost, but if you’re a larger business who wants the best options for customization and security-it could be a good choice.

Managed System. The business still owns the equipment, but the vendor takes responsibility of the hard work like set up and maintenance. This is a great ‘best of both worlds’ option, allowing you the good things about both on premise and hosted solutions. The costs are higher, and your downtime is more likely than if you went with a hosted solution.

VoIP can help your business

What to Know

Here are some of the most common VoIP related terms made simple:

Hosted PBX: Private Branch Exchange is like a private telephone network which works within a company or organization. This might be in one building, across multiple offices, or even globally across many countries and time zones. The users of the system can easily communicate with one another on one private and secure business phone network. If your VoIP provider offers a PBX, this will be using your LAN or WAN data network rather than the traditional telephone network. There are many VoIP services which offer a PBX system, including some of the top providers on the market.

Call Centers: Traditional call centers have been completely revolutionized by VoIP technology. Customer service is improved by having ‘always on’ support, with better quality and efficiency. Customers can be immediately routed to the right technician for their query, improving technical support at every stage of the game. A Voice over IP system for a virtual call center means that you can integrate headquarters, remote offices and even outsourced locations seamlessly. You can even include agents who are working from home.

Web Conferencing: VoIP can help your company make meetings easier and more efficient. Arrange for entire teams to meet ‘face to face’ without spending a cent on flights or managing dozens of schedules. Look for solutions which are multi-channel and don’t need specific hardware for a certain OS. Of course, you will need audio, video and chat capabilities. You might also want screen-sharing, uploading files, and recording functionality, too. If you’re looking to streamline your business, then web conferencing software might be for you.

Residential VoIP: As most people pay for broadband services nowadays, it’s becoming more and more common to switch from a regular landline or home phone service, to VoIP for residential purposes. If you’re used to paying for features like an answer phone, call forwarding, caller ID or call waiting, you might be surprised to learn how much you could save by switching to a residential top VoIP provider.
