Routr

The future of programmable SIP servers.

Visit Routr

Routr is a lightweight SIP proxy, location server, and registrar that provides SIP infrastructure for telephony carriers, communication service providers, and integrators. It is a cloud-native server designed to run on Docker and Kubernetes, addressing the need for a programmable SIP server that can be deployed as part of VoIP networks.

The server can be controlled through a command-line interface for remote server control, a RESTful API, or a web-based GUI. Routr ships as a Docker image that includes the server and deployment tools, and it is tested with popular cloud providers. The project provides documentation and code examples for getting started, along with community channels including GitHub Discussions and Discord.

Routr is aimed at telephony carriers, communication service providers, and integrators building VoIP networks. It is distributed as open source software; the pages do not describe paid editions, trials, or seat-based or usage-based packaging.
