As part of our ongoing efforts to deliver reliable and high-quality voice communications, Flowroute has in operation a number of PoPs across the world. These additional PoPs have been architected to leverage modern cloud infrastructure. With this update, you can connect your physical or virtual communications infrastructure to Flowroute over SIP following the specs outlined below.
