However, capturing conversations for archiving, compliance, or analytics isn't one-size-fits-all. Broadly speaking, there are two major capture approaches: - **Download-based capture** - **Real-time capture** Understanding the differences between these models — and when each is appropriate — is critical when evaluating a conversation recording and archiving solution. ## Download-Based Capture With the **download approach**, the unified communications platform itself records the meeting or call. Once the session ends, it offers a way — typically through an API — for third-party systems to download the recording. This method is often implemented via REST APIs, where recordings are listed and retrieved after a short processing delay. ### Key Characteristics - **Post-call availability**: The recording is usually accessible within a few minutes after the call ends. This allows enough time for the platform to finalize and process the file. - **Platform-controlled media**: The audio and video are recorded by the communication provider itself, ensuring consistent quality and removing the need for custom recording logic. - **Simpler integrations**: Since the recording is handled entirely by the platform, integration usually involves making authenticated API requests to retrieve the finished files. This approach is less complex and requires minimal infrastructure or specialized media expertise. - Supported by e.g. **Zoom** , **Cisco Webex**, **Symphony Cloud9** ### Ideal for - **Simple archiving and post-call processing**: Organizations that need to store calls for audit or compliance purposes, without requiring real-time access, will find this model straightforward and cost-effective. - **Scenarios where real-time access isn't critical**: If there's no need to analyze or act on the conversation while it's happening, download-based capture is often sufficient. ## Real-Time Capture **Real-time capture** enables a system to receive live audio or video streams as the conversation happens. This model is commonly implemented via technologies like SIP or platform-specific media bots that join calls as virtual participants and relay the media in real time. ### Key Characteristics - **Live access to media**: Rather than waiting until the call finishes, the system receives the media streams as they’re being spoken and transmitted. This opens the door to immediate insights or intervention. - **Low-latency processing**: Real-time capture allows for live transcription, speaker identification, emotion detection, or policy violation alerts — all while the call is still in progress. - **Complex implementation**: Building and maintaining a real-time capture system is technically demanding. It requires deep expertise in audio processing, real-time network protocols, and the specific APIs or SDKs provided by each communication platform. - Supported by e.g. **Microsoft Teams**, **Cisco Webex** and t**rader voice platforms from IPC, BT, Speakerbus** ### Ideal for - **Real-time analytics and sentiment detection**: Organizations can run speech recognition, keyword detection, or emotional tone analysis live during the conversation to assess what’s being said and how it’s being said. - **Immediate post-call playback**: Because the media is already streamed to the system, it can make it available for playback within seconds of the conversation ending—without waiting for the platform to finalize a recording. - **Highly available, redundant (2N) capture**: Real-time systems can be designed with failover and redundancy (two independent recording paths) to ensure that no critical call is ever lost, even if one recorder fails. - **Proactive alerting and monitoring**: Real-time access allows compliance teams to be notified instantly when suspicious or non-compliant language is detected, enabling quicker interventions. - **Surveillance or supervision use cases**: In regulated industries such as finance, supervisors may be required to listen to live calls. Real-time capture enables this level of oversight in a compliant and secure manner. Some use cases even require **listening in to live calls**, which is only possible with real-time capture. For example, financial firms may need supervisors to monitor trader calls for market abuse or insider trading in real time, rather than reviewing recordings after the fact. ## Our Platform: Real-Time When It Matters While we support **download-based integrations** for simplicity and broad compatibility, our platform offers **real-time capture whenever it's available** from the communication provider. This ensures we can meet even the most demanding operational and compliance requirements. Here’s how real-time support adds value: - **Start transcription before the call ends**: Real-time capture lets us process audio on the fly, so transcripts are ready almost immediately after the call finishes. - **Generate alerts or insights during the session**: We can detect keywords, sentiments, or potential policy violations as they happen — not hours later. - **Offer highly available, mission-critical capture**: For environments where recording is mandatory and system uptime is non-negotiable, we provide 2N (dual-node) capture to ensure resilience. - **Allow playback seconds after hang-up**: There’s no need to wait for the platform to export or finalize a recording — we already have the media in hand. This flexibility lets our customers meet their compliance, operational, and business intelligence needs with a future-proof recording and archiving solution. ## Final Thoughts Both capture models serve important purposes: - **Download-based capture** is simpler, easier to integrate, and sufficient for many use cases involving archiving or post-call analysis. - **Real-time capture** is more complex to implement, but enables powerful capabilities like live transcription, monitoring, and alerting — making it essential for high-stakes, regulated environments. As unified communication platforms continue to evolve, support for real-time APIs is likely to expand. In the meantime, platforms like ours are built to **take full advantage of real-time access whenever it’s available**, helping our customers stay compliant, proactive, and insight-driven.
