<\/h3>\n<\/h3>\nVoice over Internet Protocol (VoIP)\u00a0 has become a popular communications solution for small- and medium-sized businesses. There are so many providers and services to choose from, but how do you pick the right one? One crucial factor you should look into is a vendor\u2019s Quality of Service, or QoS.<\/span><\/p>\n VoIP providers and IT experts define \u201cQuality of Service\u201d as the overall performance of a VoIP system or network. This performance is usually measured by looking at objective statistics like bandwidth use, transmission (call) delay, error rates, etc. Subjective data, like what the end users think of the system\u2019s performance, are also factored in.<\/p>\n QoS does not just apply to VoIP, but also to traditional phone systems. It would not be an exaggeration to say that the quality of landline calls are near perfect. This is because all traditional phone network providers invested in physical networks and connections that offer high QoS. That means switching from one provider to another doesn’t affect the quality of the calls.<\/p>\n But investments in physical networks were expensive, and customers ended up shouldering the costs. The high cost of maintaining the transmission network (phone lines, switches, etc.) is also why there are only a couple of phone providers in your area. In other words, it’s just too costly for small companies to launch a traditional phone network system.<\/p>\n In comparison, VoIP systems are a lot cheaper to set up and maintain. This has led to a high number of VoIP providers. And because anyone with capital can set up their VoIP systems without having to adhere to a standard, the QoS amongst providers can vary drastically. To find the provider with the best QoS, ask them these three questions:<\/p>\n Almost every VoIP provider will rely on public infrastructure in order to transmit data. The rule of thumb is, the bigger the company\u2019s share in the infrastructure, the higher its QoS is. This is because the provider will have more control over the technology.What is QoS?<\/h3>\n
Why does QoS vary from provider to provider?<\/h3>\n
How much of the network infrastructure do you own?<\/ol>\n
\nOne of the best options is to look for facilities-based providers. These companies own almost all of the network that carries VoIP calls and can therefore offer better services and quality.<\/p>\nHow much traffic will run over public internet?<\/ol>\n
