Debian System Administrators working in conjunction with pkg-voip team member Daniel Pocock have set up a SIP proxy and TURN server for debian.org.

Specifically, the SIP proxy provides a way for Debian Developers to use their Debian email ID as a SIP address for making calls to other project members and exchanging calls with any other domain that is enabled for SIP. The repro SIP proxy from reSIProcate has been chosen for this project.

The TURN server provides a mechanism for users of SIP or XMPP (Jabber) to relay audio and video streams through a public IP address when necessary, eliminating many of the quality issues that arise when NAT devices block the media streams in one or both directions.

The service allows the users to connect directly with the SIP device or softphone of their choosing, including many of those packaged in Debian such as Jitsi and Empathy or third party solutions like Lumicall or CSipSimple on Android. The SIP proxy also includes a WebRTC interface, allowing Debian Developers to immediately try WebRTC voice and video calls without installing or configuring any software of their own other than a web browser.

A second stage of the project involves providing an XMPP (Jabber) server with similar capabilities for federated communications between debian.org users and other domains. Further details will be announced in the weeks ahead.

It is a significant feature of the Debian Project philosophy that we can operate the entire project using free software, specifically, using software available in Debian packages running on our own infrastructure and without a dependency on third party cloud solutions.These new services for project members fulfill those expectations. It is particularly relevant for situations where real-time communication (voice or video) collaboration takes place with third parties such as applicants for Google Summer of Code, Outreach Program for Women, sponsors, media and other free software projects.

Project specific details and a user guide are available now on the Debian Wiki at http://wiki.debian.org/UnifiedCommunications/DebianDevelopers
