What is Business VoIP?

No matter the development phase your business is in, whether it’s a startup or a company that is already growing and expanding, you will always strive for further development, higher efficiency, and independence.

However, these goals are challenging to achieve without a well-thought-out business plan, which will reflect all the critical success factors: right working conditions, production, and customer-oriented processes, as well as a communication strategy.

Thus, the vital role of communication systems in ensuring effective communication both within the company and beyond shouldn’t be overlooked. An outdated phone system is a serious obstacle to business growth because it practically does not scale, poorly integrates with other platforms, and is too expensive to maintain.

VoIP (Voice over Internet Protocol) or IP-telephony is voice communication over the Internet (in contrast to traditional telephone communication performing via telephone lines or a mobile GSM/3G network). One of the essential advantages of today’s IP-telephony, attracting numerous customers, is affordable or free long-distance and international calls.

At the most basic level, Voice over Internet Protocol (VoIP) is the process of converting analog audio into digital packets that can be delivered over the Internet. In plain language, VoIP allows you to make a phone call in much the same way you send an email. Like most other Internet technologies, VoIP has a clear advantage of the ability to use it on multiple devices, having an adequate Internet connection.

This means that VoIP phone services can be received from your computer, on a mobile device, or from a desk phone (terminal). At a more technical level, VoIP is a way to make calls over your local area network (LAN) or wide area network (WAN). VoIP technology turns your analog voice into digital packets, which are sent over the IP network to your final destination.

On-premise vs. cloud-hosted solutions The VoIP telephone system uses your local area network (LAN) as the foundation of your system. When you connect your VoIP devices and your VoIP service provider to a VoIP PBX, you are likely to use HD-IP phone devices for communication. The VoIP telephone system uses IP technology to handle call management and manage your WAN connections.

Although a VoIP phone uses VoIP and is connected to your local network, most systems can directly connect to a public switched telephone network (PSTN). This provides you the ability to use both VoIP and PSTN for your call. Two main options VoIP phone systems exist:

On-premise
Cloud-hosted service

Mostly, VoIP telephony systems are what you can imagine when you think of a traditional business telephony system. These include hardware and software IP phones, as well as any other necessary equipment to connect to your VoIP network (gateways, etc.). IP PBXs can save companies money, time, and IT resources, and they also have the added benefit of increased flexibility, scalability, and ease of use. These are the benefits of all IP PBXs, regardless of deployment type.

Permanent solutions (on-premise)are great for enterprises that expect their communication needs will remain relatively stable in the foreseeable future and are willing to make upfront investments that will save money and improve business communication. The VoIP hosting systems are often called cloud or cloud-based phone systems because they operate in the cloud.

Cloud is a terminology that has been used very often these days. Commonly, cloud means a server or a network of servers that store information or provide data. For example, a traditional phone system will require you to store all of your communications equipment in a closet somewhere in your building or office.

A cloud-hosted phone system does not require physical equipment at your location. The entire phone system “lives” (or is located) on a server somewhere else on the site or the data center, so you do not need to purchase, install and maintain expensive phone line equipment. Cloud-based systems also give you the opportunity to access your phone system on virtually any device that has Internet access, which is a considerable advantage for more mobile or remote operations.

How to Choose the Best Business VoIP Provider

Requirements for the quality of communication in business are much higher than in everyday life. A lost connection is a lost customer. Noise, lags, and cut-offs are unacceptable for business, so it is so difficult and so important to select the best business VoIP provider. When using telephone contact automation tools, the quality of communication begins to play a decisive role: speech recognition is very demanding on the quality of the audio stream.

The communication quality directly depends on your IP provider. Specifically, it also depends on the Internet provider and the speed of the Internet channel. But precisely, the VoIP provider is responsible for transmitting voice from one user to another. It is essential to get a clear signal without interference, malfunction, or ambient noise in the handset.

Good web proxies and other equipment are obligatory to succeed. Now we move on to the selection process. Make a list of providers in the market First of all, decide whether your business needs on-premise or cloud-based phone service. This will help to narrow your search among the companies offering service plans you need.

Do not forget to ask for recommendations from colleagues or partners already using VoIP service, examine the search results, and independent ratings. You can immediately cut off those providers who do not offer services or features (toll-free numbers, local numbers, call recording, etc.) you require. Estimate the budget and needs Try to answer the following questions:

How much do you assume to spend per month (what is the affordable budget for your company to spend on communication)?
Where will you call most often?
How many lines do you need (how many employees will use the virtual PBX)?
How many offices do you have and where are they located?
Do you need additional services and options?

If you don’t have an intensive calling or the budget is limited, choose those who offer inexpensive rates with basic options. For example, Nextiva’s Basic plan for $20/mo/user allows unlimited calls and faxing with toll-free and local phone numbers.

If you have worldwide offices and customers, and plan to connect more numbers and lines, choose large-scale VoIP providers whose services may be more expensive, but they offer more options and opportunities. Then study the price list for international calls, especially for the locations you need to call most frequently. Multiply by the average number of calls per month, add to the subscription and connection fees, and compare the amounts for each operator.

Compare services from different companies Decide how many employees will use the phone service, i.e., how many lines you need. See how the price will change with the minimum and maximum quantities, for example, for 5 or 15 lines. Perhaps in the future, you will need more, and it is better to estimate the costs immediately. The most requested additional features are:

800, 888-833 numbers (toll-free numbers when you pay for the call, not the client)
Smart call-back for a call back from the site (the client orders a call, and the system automatically dials from a free manager)
Record and statistics of the conversations that are stored in the cloud archive

The more useful options and services the VoIP provider offers, the better. Even if you have already found a provider but for any reason were not satisfied by something, feel free to change it to the one who is more convenient to work with and can provide the services of better quality.

Some Questions to Ask a Potential Business VoIP Provider

VoIP phone systems are suitable for business of any scale and orientation. Cost reduction, in general, is one of the main advantages of using VoIP technology compared to traditional phone lines. The business also requires the additional IP phone service functions like conference calls, voice mail, caller ID, an ability to send an email and/or voice mail to a mobile phone, or the features of custom call filtering and call forwarding.

The perfect VoIP provider for business combines the two most essential components: the price and quality, satisfying the maximum number of customer’s needs for a minimum fee. At the same time, we must not forget about technical relevance, especially speaking about the IT market and the products it provides.

Also, be confident to pay attention to the quality of communication with your chosen operator. An essential criterion is the security of communication channels and subscriber accounts from hacking, as well as protecting customers from the theft of passwords and fraud. Moreover, the process of finding the right VoIP provider for your enterprise necessarily includes direct communication with the customer service or support team of the chosen IT company.

So, here follows a couple of tips on how to determine whether this operator suitable for your needs or not. First, evaluate how they work with clients: ask questions via chat or phone, outline your needs and budgets, and see what they answer and how. If you were responded to immediately or within a few minutes, this means that the company will respond to your future requests at the same speed.

And if you had to wait a few days for the answer, it smells bad. It is safe to predict that all your problems that will arise in the process of using services from this company will be resolved just as quickly. Consider those companies that allow testing various options and services for free.

It makes it easier to understand what you really need and how difficult it is to figure out how the whole system works. It is clear that in addition to technical issues, there are other questions to the IP service provider. The most important of them are briefly mentioned below:

Competent technical support team. (Are your questions clear to them, and are you happy with their answers?)
The ability to receive detailed reports on completed calls. (Do you have plans with detailed analytics and reports? Where the call information is stored?)
The ability to manage the service through a personal account on the site (for cloud-hosted solutions). (Which tools I can use to manage my account?)
Month-to-month billing, absence of cancellation fees. (Should I sign an annual contract or you have monthly billing system?)
Free-trial period. (Do you have a free-trial period to test your network?)

In general, connecting to an IP telephone system is a wise choice for many companies, given the use of advanced technologies and reduced costs. Careful selection of the most suitable business VoIP provider is the best way for your business to grow, taking advantage of the modern type of communication.

Key Benefits of Using VoIP for Your Business Phone Service

The main benefit of VoIP for enterprises is the ability to build more efficient corporate communications systems with various voice services. The efficiency of such systems (compared to traditional ones) is quickly confirmed by the following benefits they offer:

Easier and cheaper system’s roll-out (because VoIP systems are built based on existing intranet networks or cloud solutions used)
Free internal voice communication within the company (even with a geographically remote business structure)
The ability to access all communication capabilities in office and while business trips (via the Internet)
The ability to integrate voice services in business applications and business processes
The advanced features for call recording, conferences, and statistics
Mobility and flexibility

Many VoIP services offer different software features, including mobile apps allowing customers to use their business phone lines from any mobile device. Thus, you are free to make and receive calls from anywhere. Another extremely attractive advantage of cloud-based VoIP telephone systems for small businesses and entrepreneurs is their flexibility and ability to expand or customize service plans for the needs of your company.

If your business is snowballing (or has the potential for rapid growth), or if your business is seasonal, it would be meaningless for you to buy a limited number of phone lines and phones. With traditional business phone systems, growing or declining resources can become expensive.

But cloud-based VoIP systems are different. Resulting using your Internet connection for VoIP system instead of physical telephone lines, resources can often be added or reduced easily, making transition periods easy for your business.
