For VoIP calls, we recommend an upload and download bandwidth of at least 100 kbps per line. Don't think that a one megabyte connection is enough for ten VoIP phones. You need at least one megabyte of available, dedicated bandwidth to handle ten high-quality VoIP calls at the same time. You also need to budget for other activities, such as entering leads into the sales CRM, holding webinars or streaming music.
To accurately estimate the amount of bandwidth needed for your company's VoIP, you should have a basic idea of how many simultaneous calls you and your employees will be making. Typically, you will need between 85 and 100 Kbps per simultaneous VoIP call. Keep in mind that the more surfing activity, the less bandwidth will be available for VoIP calls. The most important aspect to consider is the number of employees making calls and how many calls will occur simultaneously.
The general range for bandwidth needed is 85-100Kbps for each concurrent VoIP call. Bandwidth is measured in kilobytes per second (Kbps). To avoid bandwidth-related call quality problems, it is necessary to determine how much bandwidth will be needed to support a new VoIP phone system, as well as existing Internet usage requirements. Different people or downloads that need to consume bandwidth share the level of bandwidth set so that their Internet connection can do things like download files or make VoIP calls.
VoIP calls are often a large consumer of bandwidth because they require more bandwidth to transfer voice data than, for example, a simple text. As businesses and home users move away from traditional analogue telephone services, replacing them with Voice over Internet Protocol (VOIP), one of the challenges is to allocate the right amount of bandwidth to their Internet phone service. But there is something very important to keep in mind about bandwidth and that is that the, for example, 1Mbps of bandwidth you would use to make 12 VoIP calls covers only those calls. Considering that phone calls are still the primary channel of communication with customers (source), it is especially important that your company does not let the lack of VoIP bandwidth affect your customer-facing communications platform.
Bandwidth is one of a number of important aspects of your VoIP phone system configuration that is critical to success. By completing a VoIP speed test, you will get a good idea of how much bandwidth is available to your business phone system. Connections such as Wi-Fi and Ethernet have to handle other network features (such as packet headers and control messages) that also consume bandwidth in addition to the files and data you are trying to transfer (such as a VoIP phone call or a movie). The speeds listed above are suggested minimum speeds for VoIP use only: you will need higher bandwidth so that your phone usage does not affect other parts of your business.
However, while transferring your phone lines to a VoIP configuration is relatively straightforward, there are some key criteria you should check before making the switch, including Internet speed, also known as bandwidth. Your Internet service (and bandwidth, specifically) are incredibly important to the success of your VoIP phone system. One of the key steps to successfully moving to a VoIP phone system is to be able to plan precisely how much bandwidth or data you will need.
