The Bono nodes form a horizontally scalable SIP edge proxy providing both a SIP IMS Gm compliant interface and a WebRTC interface to clients. Client connections are load balanced across the nodes. The Bono node provides the anchor point for the client's connection to the Clearwater system, including support for various NAT traversal mechanisms. A client is therefore anchored to a particular Bono node for the duration of its registration, but can move to another Bono node if the connection or client fails.
Note: This is my attempt to build the container - but I recommend using docker-compose to orchestrate and put everything together. Check out - https://github.com/Metaswitch/clearwater-docker
Thanks Project Clearwater team.
