The desire for convenient communication has led to advancements and invention. A critical development that has revolutionized telephony is VoIP. A good communication system should be reliable, comfortable and affordable.

Cost is a vital factor in defining the viability and usability of a given method. VoIP relies on data to enable communication and costing can be is determined by the amount of data. VoIP has matured enough, and an assessment of its efficiency is necessary, through managed IT services VoIP can be easily managed for your company.

A comparison between the present and the traditional, and test on feasibility is a must. Is VoIP the solution to your communication? Let’s see the answer on the basis of data usage thus affordability.

VoIP use

Voice over internet protocol (VoIP), uses the codec to transfer multimedia content. VoIP does away with circuit-switched connections thus minimizing the infrastructure cost. Notable pros of VoIP telephony include flexibility, enhanced productivity, portability, and accessibility. A questionable advantage of VoIP is in the cost-saving aspect.

Connection in a VoIP relies on internet connectivity, and data cost is thus a good measure of cost-effectiveness. VoIP can use a standard internet connection to ensure “free phone calls.” The only cost incurred comes in buying of data.

There are many VoIP providers worldwide considering the rapid expansion in IP telephony. Analog telephone adapter, IP phones, and computer-to-computer are the common forms VoIP services. The service provider may vary from region to another. Vonage, for example, is a US-based company which has been in the market for long enough. Some of the VoIP software is available on the internet for free. If you think of trying it out, the free versions are good since you will only spend on data.

VoIP call cost

Overly, you will spend way much less when you make VoIP calls than the traditional phone system. When calling someone on the same service, for instance, Skype, the calls are free. Even calling a landline will still cost significantly lower costs. The cost comes in hidden and sometimes may go unnoticed if it is not the sole purpose of internet use. Data cost will inform how active VoIP call is. The dent on your data plan can be worrisome depending on how you use VoIP.

How much data does VoIP use?

Data use in making the VoIP connection will vary depending on how one uses the VoIP service system. This is dependent on the desired quality of connection while making calls. Some of the factors that will determine your data usage include bandwidth used, quality wanted and optimization. These define the system’s data usability and will help you establish costs. Sometimes, you may have to converse with your vendor to get clarifications on how much data is getting used.

VoIP data determinants

The volume of calls; this refers to the number of requests you make or receive in a given duration of time. You can establish a trend and ask your vendor to advice on data usage. A clear understanding of your call volume is crucial to plan on VoIP data use. When you make longer calls or a high number of requests, then you are likely to use more data.

Desired bandwidth; bandwidth refers to the most massive transfer rate of data. A higher call volume will mean a high bandwidth. VoIP uses a lot of bandwidth and can vary depending on the connectivity reflected on the costs. High bandwidth maintains high voice quality during a VoIP call and reduces latency. Thus, it is recommended that you have a higher bandwidth than you need.

Optimization of call quality; having servers set to focus on VoIP calls can have data implications. Keeping call quality high is essential for clear audibility seen in traditional forms. Sometimes, this can be achieved by data security settings which will affect data usage.

The question on how much data a VoIP can use is one that is frequently asked. Figures don’t lie, and although variations exist, a rough estimate is possible.

VoIP voice calls

To achieve a good quality voice call high sound quality and higher data connectivity is vital. Most of the reliable VoIP services use the G.729 codec to convert speech into HD digital signals. Skype and Facetime use G.729 codec. Inasmuch as sound quality is guaranteed, this comes with a higher data cost.

The amount of data used by a codec is proportional to the quality of service rendered. G.729 use approximately 30 megabytes per hour. G.723.1, which is the most economical uses approximately 0.33 MB per minute (20 MB per hour). At the extreme high end is G.711, which employs about 1.3 MB of data per minute (78 MB per hour). It is essential to create a balance between quality, bandwidth needs, and costs. Besides, you should have a service that provides excellent sound quality and at the same time use fewer data.

Video calls in VoIP

Video calls generally use more data compared to voice calls. Further, additional factors come into play such as video quality, screen size, and device specifications. Connecting non-compatible devices will, for instance, need more data.

A video call between two small mobile devices, for example, a smartphone will use fewer data. Connecting a smartphone and a computer will consume approximately 270 megabytes hourly.
Video quality is also a critical determinant of how much data a video call will use. A standard video can use as low as 190mbs per hour. When you desire HD videos, you can use an average of 1.25 GB per hour. All these will contribute to the cost of a given connection in VoIP. Setting a data plan and securing connection is helpful in helping you reduce your data usage. Sometimes, you may require a monitoring device to record trends in data use and establish a plan with the vendor.

In conclusion, data usage by VoIP is considerable, and the appropriate budgetary mechanism is necessary. However, VoIP SIP-based telephony still has a tremendous cost-saving advantage over traditional phones. Getting a suitable data plan from a reliable service provider can provide a solution.
