How much bandwidth is required for VoIP service?

Using a VoIP system is a cost-effective communication service for businesses. The system is Internet-based and traditional telephone lines are no longer required to make and receive calls. Due to the dependence of VoIP system on the Internet and the importance of maintaining communication with customers, you need to be sure of the quality and speed of your business Internet. In this article, we are going to mention the criteria of choosing the proper bandwidth required for VoIP service.

Bandwidth is the ability to transfer data from one point to another over a specified period of time. The more bandwidth you have, the more data you can send over your broadband internet. Since audio data is much larger than textual data, and because the VoIP system is Internet-based, you need to provide Internet bandwidth that is matched to your business needs.

Before setting up VoIP system in your company, you need to consider the amount of bandwidth required for this service. The bandwidth required for your VoIP phone service depends on the number of simultaneous calls. As you know, bandwidth includes both download and upload speeds. Obviously, the faster the data upload, the better the quality of your calls, and if the upload speed is low, there will be a possibility of interruption and interference in your calls.

In shared bandwidth such as ADSL, the bandwidth is usually sharing among users and the download and upload speeds are always changing, and at peak times there is a possibility of slowing down and the VoIP system may face problems. For this reason, we suggest using a dedicated bandwidth service. Depending on your organizational needs, different speeds and capacities are defined for dedicated bandwidth, of course, 100% of it belongs to you and you can use it without speed and traffic limitation.

If you are using call center and CRM software in your organization, it should be considered in your bandwidth amount. Video calls also require about 3 to 20 times more Internet compared to voice calls. Other activities, such as surfing the Internet, working on various websites, using emails, etc., also need specific amount of bandwidth. Therefore, you need to consider each of these before choosing your bandwidth service.

A series of codecs are used to encrypt and compress data over the Internet. Each of these codecs is for different data such as audio, text and fax data, which converts them from analog to digital data packets. These codecs have a great impact on sound quality, so it is necessary to use the right codecs to achieve the desired quality in calls.

The minimum bandwidth required for a VoIP system, excluding other uses such as Internet browsing, video calling, e-mail service, and etc. for a voice call, is approximately 100 kbps. This amount of bandwidth required will increase as the number of simultaneous calls increases. As a general rule, VoIP calls typically require 100 Kbps or 0.1 Mbps. Therefore, if your upload speed is 10 Mbps, your network should be able to handle a maximum of 100 VoIP calls simultaneously. However, this number is usually limited to 10 or 20 calls, as there are other activities using the network.

Since VoIP technology is based solely on the Internet, the quality of your calls depends on your Internet service. When switching from traditional telephones to VoIP technology, always run bandwidth speed tests and do not forget the factors mentioned above that may affect your bandwidth.

As mentioned before, you need to have enough bandwidth to make high quality VoIP calls. If the quality of your calls is poor, you can change your router settings and set your data network priority over voice calls. This prevents other programs from affecting the quality of your business calls.
