What is VoIP… really?

Last week, we touched on some of the technological advances that have allowed VoIP telephony to surpass the PSTN in both quality and reliability.

Yet, even though VoIP has been around for two decades, there are still some misconceptions about what it really is. A lot of people think of VoIP as a technology that allows placing phone calls over the internet. Although this is true, such a narrow definition encompasses only a fraction of the functionality of VoIP.

The unfortunate consequence of this misperception is that VoIP is often associated with low quality and best-effort services that offer low cost or free voice calls over the internet. Those familiar with these services have experienced the frequent disconnects, jitter and stuttering on the line characteristic of this type of service. As a result, VoIP has erroneously been associated with an unreliable user experience.

The truth is, VoIP is much more (and better) than just voice over the internet.

Voice over internet protocol, as its name suggests, is a technology that allows for the digitization and packetization of analog voice signals in a format that can be transmitted over an IP network. There are four types of IP networks on which VoIP operates. One is the internet, which is its least functional use case. The more significant ones for private and enterprise users are customer premises networks, SIP trunks, and mobile networks.

Customer premises networks

Enterprises and organizations worldwide have private IP networks in their buildings and branch offices to connect their employees with internal network services. Many universities and public sector organizations maintain geographically extensive private IP networks for interconnecting and providing network services to their locations. All these networks, which are also called LANs (local area networks) and WANs (wide area networks), depending on their geographic reach, comprise infrastructure over which VoIP can operate. Although most of these networks do connect to the public internet, their infrastructure is managed privately and thus they function in a very controlled environment.

Because VoIP shares the same infrastructure as data networks, it can be implemented wherever the organization’s private IP network is available. An IP PBX can be installed at the core of the network and IP phones can be physically located anywhere on the network topography. This makes VoIP telephony more scalable and flexible than a legacy TDN PBX used for analog telephony.

SIP trunks

The other domain in which VoIP operates is on the telecom service provider side (telcos or network operators). This is very different from the best-effort voice services described earlier. A toll-grade VoIP telephony provider provides packetized voice services over a controlled network, not over the public internet. This is in the form of what are called Session Initiation Protocol (SIP) trunks. SIP trunks deliver VoIP in conjunction with Quality of Service (QoS) mechanisms that ensure the voice packets arrive at their destination in a timely and orderly manner, thus maintaining the voice quality that users have come to expect. The counterpart of this network in traditional telephony is the Public Switched Telephone Network (PSTN) or an ISDN PRI voice circuit.

Mobile networks

Mobile telephony networks are a special case of networks that provide both voice and data from end to end. In other words, these networks don’t have a natural demarcation point that separates the customer premises from the operator’s network; the network instead extends to the handset itself.

Mobile operators, too, offer a privately controlled and managed network environment on which VoIP services can be successfully deployed. In the case of mobile, voice is most often carried using the GSM standard, which uses Time Division Multiplexing to digitize voice (similar to an ISDN voice channel), or the CDMA standard, which uses Code Division Multiplexing to digitize voice. However, some mobile telephony operators do instead use VoIP to transmit voice to their subscribers.

Another way that VoIP can be used to transmit voice over a mobile network is via OTT (over the top) applications (think Skype, WhatsApp, etc.) that send voice as data packets. However, because this type of data travels part of the way over the internet, the quality is not as reliable.

CONCLUSION

Much more than merely allowing users to place phone calls over the internet, VoIP is a technology that provides a high-quality, flexible and easily scalable internal telephony infrastructure within the domain of private IP networks, as well as reliable and low-cost routing of voice calls worldwide.

Reason to Swap your Old PBX for a VOIP Hosted PBX

Looking for A Reason to Swap your Old PBX for a VOIP Hosted PBX — How About Eight Great Reasons!

1. Lower CAPEX Costs: Buying a traditional phone system is like buying a new car, it significantly depreciates the day you place it in service. Plus, you own a piece of equipment that you’ll have to one day replace. You can put that money to better use by spending less up- front by intstalling a VoIP Hosted PBX system.

2. VoIP Hosted PBX is Dynamically Scalable: Up-size and Down-size on the fly. VoIP Hosted PBX Service lets you buy the exact number of users you need right now – later you can add users when you actually need them. This helps preserve capital in comparison to guessing what size PBX system you need to buy today to support the number of users you think you’ll have in 3 – 5 years.

In the future, there’s a good chance with a traditional PBX you’ll be at the manufacturer’s mercy for repair and expansion since only their parts will work with your purchase.

Business Voip Requires Reliable Internet Service

Looking for a way to decrease your phone service costs for your small business? Business voip may be the answer you’re looking for. Compared to a traditional pbx phone system and using business voip, business voip can save you money with upfront phone system equipment costs as well as individual phone call costs.

Instead of paying upfront for your business phone system equipment business voip services offer hosted pbx which means you don’t have to make that initial phone system equipment investment. Your business voip provider will already have the phone system equipment and you can access your assigned phone system via internet through your hosted pbx business voip provider services. Using a business voip provider’s hosted pbx services is usually ideal for the small business who would rather make small monthly payments for the business voip phone service rather than paying for the phone service and the phone system equipment. Hosted pbx also saves space and resources for the small business. When using business voip provider’s hosted pbx system, a small business doesn’t have to have a special room or space for their pbx phone system nor does the small business have to pay an extra employee to update and maintain their pbx phone system.

Business voip saves on phone equipment expenses as well. A regular laptop or computer today can use make and receive a phone call using business voip because all the computer needs is internet service and a microphone and speaker. An advantage to business voip phone calls using computers is also making video phone calls. A business can make conference calls using business voip and at the same time help business employees talk face-to-face on the computer via camera. This saves costs on business travel as well. Business voip conference calls allows you to put a face to a voice over the business voip phone call without flying a person out to the other business location.

Business voip isn’t only ideal for the small business, but it benefits a large business also. However, when a large business uses business voip for a call center, for example, that business must ensure that their internet service and bandwidth will be able to handle the amount of internet use for simultaneous multiple phone calls.

If you are considering business voip, having a quality phone call goes hand-in-hand with having quality internet service. Because business voip sends and receives phone call data digitally over the internet, having enough bandwidth and a reliable internet service is vital to a quality business voip service. You can have the best and highest quality business voip service, but without a reliable internet service, your business voip service won’t matter. With irregular internet service voip phone calls can be disconnected or full of static. Business voip runs on the internet, so without internet you’re without phone service and a phone system. No internet? No phone calls.

Without the required bandwidth for business voip, your phone calls can also be choppy and full of static because digital data for the phone call won’t be sent and received as it should. As your business voip provider what the internet requirements are for their business voip phone service to run at top quality. Business Voip Requires Reliable Internet Service

Business voip isn’t only ideal for the small business, but it benefits a large business also. However, when a large business uses business voip for a call center, for example, that business…. Learn more at business voip and unlimited.
