Internet telephony, broadband telephony, and broadband phone service are synonymous and refer to communications services such as voice, fax, SMS, and multimedia delivered over the public Internet.

In short, VoIP lets you make phone calls over your broadband internet instead of a traditional phone line.

For a VoIP phone system, you will need a broadband Internet connection such as DSL, Cable, T1, wireless, etc. Internet requirement for VoIP depends on a number of variables. In general, you should have at least 100kbps on both upload and download.

The bandwidth required for VoIP calls depends on the codec used. The codecs optimize the media based on application requirements and network bandwidth.

For example, if your VoIP service uses a non-compressed codec (G711), the bandwidth required will be about 100kbps of both the upstream and downstream. In such a case, every 1000 minutes of call will use about 1.5 GB of bandwidth.

Here are the things you should look for in your VoIP system:

  1. Features

    VoIP services generally offer as part of the basic monthly fee many features, such as call waiting, call forwarding, voicemail, call forwarding on busy, etc.

  2. Integrations

    Determine if your VoIP service provider offers integration of other services such as faxing, alarms, CRM, and credit card machines, etc.

  3. Customer service and Technical support

    This is an important criterion for selecting a VoIP service. All the features and integrations will not be of much help if your communication system is down for long periods.

If you're using hosted PBX (Private Branch Exchange) or residential VoIP, apart from a high-speed internet connection, you would need an IP phone or an ATA adapter.

For a cloud communication system, you don’t need much VoIP hardware to get started. It can be set up with a physical phone by using an adapter/router, or with a smartphone/computer.

Hosted PBX or an Internet Business Phone System refers to a VoIP business phone system service that is offered by a provider that hosts physical servers running users’ services at a separate location.

You typically access the service via a direct network connection. Hosted PBX services provide you with full functionality without any “PBX hardware” on your premises. This service is therefore delivered entirely through the internet. Since this service is scaled to a predetermined size, it doesn’t offer flexibility or scalability. All the features are uniform and the service is constant.

An on-premise business VoIP phone system is where all the hardware is at your physical location. In this system, calls are passed through your own server over a dedicated voice network connection. On-premise business phone networks have higher upfront installation and maintenance costs as well as longer implementation time.

However, it gives you more control over the call quality and reliability. It is more customizable and flexible. In addition, the cost of ownership is lower when measured over a long period.

One of the best features of VoIP phone systems is how easy it is to move. You do not need to wait for a technician to run the phone wires at the new office. You can simply take your computer and/or handset to the new location, connect to the broadband, and start using your VoIP phone service.

Adopting A Business Phone System

Adopting VoIP technology may seem a little daunting in the beginning. However, the benefits are immense and you will reap the rewards even far into the future once you adopt VoIP.

For small and medium businesses VoIP offers a host of useful features that bring more value than the savings in call cost. IP telephony and unified communications offer many integrations that make your business much more efficient as well as professional.


IP networks that do not have a proper internet connection can get easily congested. This can result in dropped calls and/or poor voice quality. Therefore, you need to make sure that your IP network has a stable internet connection and sufficient bandwidth.

Unlike traditional phones, a VoIP phone system requires power. VoIP phones and routers depend on the main electricity lines for power and will go off if there is a power outage. This can be mitigated by installing a UPS. Also, using PoE (Power over Ethernet) will immensely simplify your IP telephony network.

There is a lot to handle if you want to set up a VoIP phone system properly for business use. But, the investment is worth every penny and will start giving returns immediately.
