Using MikroTik's 'Firewall Mangle', you will need to tell the router which types of connections are being used for VoIP, then mark each packet for later processing in Queues. Although QoS will help in many situations, it is not a silver bullet to solve VoIP quality problems on poor connections and is therefore not recommended to be used with high latency bandwidth types such as DSL or satellite. VoIP does not require a large amount of bandwidth but it relies on low latency and jitter as voice communication is happening in real-time. In this article, we have included a useful configuration guide to assist with Quality of Service best practices using MikroTik. VoIP is fast becoming the industry standard for office telecommunications and as more people work from home, it makes sense to ensure traffic is prioritised adequately to deliver voice packets smoothly.
