Our focus with this bridge is to offer a credible and high-performing alternative to dominant proprietary solutions, such as Teams and its \"Telephony System\" licenses.", "description": "XiVO SIP bridge project presented a significant development challenge, underscoring its disruptive and creative nature. This wasn't a simple assembly of existing technologies, but an engineering effort to bridge two fundamentally different protocols: WebRTC used by Matrix ecosystem and SIP from the IP telephony world.\r\n\r\nThis bridge (built as a Synapse module for now) allows Element to integrate enterprise telephony capabilities provided by XiVO, open source IPBX using Asterisk.\r\n\r\nThe integration approach between XiVO telephony and the Matrix protocol involved designing specific gateways and APIs for interoperability of identities (XiVO user vs. Matrix user, i.e., phone number vs. mxID) and telephony features (answer, hang up, hold, etc.) directly within the Element Web interface.\r\nThe impacts, and outcomes of this successful bridge project are significant. It allows a substantial reduction in communication costs for businesses by eliminating proprietary telephony licenses, all within a single, open-source unified communication tool. It also creates value for the French and European open-source ecosystems.\r\n\r\nIn short, the XiVO/Element bridge is not a mere improvement on existing solutions but a disruptive proposal that creates a \"bridge\" between the world of traditional telephony and modern unified communications. It, nevertheless, required solving complex problems:\r\n- How do you reconcile different protocols and semantics? The SIP protocol manages specific states and signals (e.g., INVITE for ringing, HOLD for putting a call on hold) that have no direct equivalent in the Matrix protocol. The difficulty lies in designing a mechanism capable of interpreting these SIP events, translating them into relevant Matrix events, and vice versa, to maintain a consistent user experience.\r\n- The bridge must be able to robustly track the state of these sessions and ensure that actions performed on one side (for example, rejecting a call in the web interface) are correctly executed and reflected on the XiVO PBX in SIP. A failure in this IPBX/Matrix synchronization could lead to inconsistencies (e.g., a call that still appears active on one side even though it has ended on the other).\r\n\r\nThe idea is to use this presentation to share our progress on this bridge, its integration into our soft-fork of Element (xivo-connect) with a supporting demo, and our expectations to integrate it into Tchap (French gov soft-fork of Element).

The changes might seem very small but have a very big impact in how good it fits into the matrix eco system.

However, unlike E2EE, the effectiveness of these tools depends on large anonymity sets, making widespread user adoption critical. This talk presents a research study with 189 users of messaging apps about their perceptions of \"untraceability\" as a concept, as well as their opinions on the widespread availability of tools for untraceability. The study explores their perceptions of  \"untraceability'' from a broad conceptual standpoint; rather than focusing on a particular tool or implementation, we analyze how users reason about what features should be incorporated by two fictitious messaging platforms, Texty and Chatty, to prevent third parties from \"knowing who communicates with whom\". The results point to a critical gap between how users and privacy experts understand untraceability, as well as tensions between users that see untraceability as a protection to individual privacy and users that see it as a threat to online safety and criminal accountability.

These custom events encapsulate shape and drawing data and are shared via the room timeline, enabling clients to reconstruct a consistent, persistent view of the board over time, even across network disconnections or when joining later. However, while this model ensures eventual consistency, it falls short for real-time interactions that require low-latency feedback, such as live cursor movement or simultaneous drawing. For these use cases, a dedicated real-time transport layer is essential.\r\n\r\nUsing WebRTC, we initially added a real-time layer to NeoBoard that enabled low-latency peer-to-peer communication between users. However, this relied on a full-mesh topology, where each client maintains direct data channels with every other participant. This architecture quickly becomes unsustainable as the number of users grows, due to quadratic bandwidth and connection overhead. Additionally, WebRTC depends on ICE negotiation using STUN and TURN servers to establish connectivity across NATs and firewalls, which is often unreliable and can introduce additional latency and server load. The resulting variability in connection quality and resource usage made it difficult to deliver a consistent experience at scale.\r\n\r\nGiven the success of Element Call's adoption of MatrixRTC and LiveKit, we decided to move forward with an alternative real-time data layer based on these technologies that, given enough backend resources, can scale indefinitely.\r\n\r\nIn this talk, we\u2019ll cover:\r\n\r\n- The architecture and design of NeoBoard\u2019s real-time layer \r\n- An overview of relevant MatrixRTC spec proposals and their role in our migration\r\n-  Implementing MatrixRTC with a LiveKit backend, including: \r\n    - Session membership management\r\n    -  RTC focus handling\r\n    - Infrastructure considerations and requirements\r\n- Live demo\r\n- Key challenges and what\u2019s next", "recording_license": "", "do_not_record": false, "persons": [{"code": "XCPW88", "name": "Milton Moura", "avatar": "https://cfp.2025.matrix.org/media/avatars/XCPW88_BSFEFV4.webp", "biography": "Matrix specialist and software engineer working at Nordeck, building products and services built on Matrix.", "public_name": "Milton Moura", "guid": "cff2c66d-8fb3-56e3-831e-6b98c502e851", "url": "https://cfp.2025.matrix.org/matrix-conf-2025/speaker/XCPW88/"}], "links": [], "feedback_url": "https://cfp.2025.matrix.org/matrix-conf-2025/talk/TM3ASG/feedback/", "origin_url": "https://cfp.2025.matrix.org/matrix-conf-2025/talk/TM3ASG/", "attachments": [{"title": "Slides", "url": "/media/matrix-conf-2025/submissions/TM3ASG/resources/Scaling_R_5RmJIMy.pdf", "type": "related"}]}, {"guid": "1967283f-2406-5430-a62c-aa736416dc88", "code": "8N8HZS", "id": 73143, "logo": "https://cfp.2025.matrix.org/media/matrix-conf-2025/submissions/8N8HZS/Element-Server-Suit_9HEqRmb.png", "date": "2025-10-18T13:35:00+02:00", "start": "13:35", "duration": "01:30", "room": "Alan Turing", "slug": "matrix-conf-2025-73143-getting-started-with-element-server-suite-community", "url": "https://cfp.2025.matrix.org/matrix-conf-2025/talk/8N8HZS/", "title": "Getting started with Element Server Suite Community", "subtitle": "", "track": "Hands-on", "type": "Workshop", "language": "en", "abstract": "Join us for an introduction to the Element Server Suite Community, the simplest way to deploy a Kubernetes-based Matrix 2.0-ready stack, maintained by Element. \r\n\r\nThis workshop will deploy all the components of the suite: a Synapse homeserver with Matrix Authentication Service enabled, a Matrix RTC backend for calls, and an Element web client. \r\n\r\nYou'll be able to try it on your local laptop using your Docker daemon, or deploy it on a virtual machine with a single-node Kubernetes setup. \r\n\r\nWhether you're new to Kubernetes and Matrix or looking to expand your server capabilities, this session will give you the foundation to get started and experience the latest Matrix features on your own machine.", "description": "This workshop introduces you to the Element Server Suite (ESS), a streamlined and user-friendly way to deploy a Kubernetes-based Matrix 2.0-ready stack.
