Many premises will have PSTN phone systems which are connected to copper cabling. For the NBN rollout the copper cabling to the exchanges are swapped out for optic fibre to the DSLAM or premises. Because of this, phone services are moved to VoIP (Voice Over Internet Protocol) which requires a router to provide the phone services. In most cases, the service provider will supply a basic router providing connectivity to the internet and VoIP services whilst retaining the same phone number. For most households, the ISP provided router will be sufficient, but this may not be the case for many businesses. Especially for businesses requiring features such as a VPN, firewall security, user management, Quality of Service or others. This requires replacing the basic ISP supplied router with one of business grade routers we supply. A particular problem faced by many users is that, if they want to retain their current phone number (an important consideration for most businesses), they are forced to use the router supplied by the ISP. This is due in large part to service providers not providing the VoIP configuration details to the customer. Details including the SIP configuration settings, and the username and password for the VoIP account are held on the device only.
