CALEA compliance
VoIPmonitor can meet CALEA (Communications Assistance for Law Enforcement Act) requirements by programmatically exporting recorded call data to third-party compliance systems via the GUI API.
Overview
VoIPmonitor records SIP and RTP streams, storing both packet captures (PCAP files) and audio recordings (WAV/OGG files). This data can be accessed programmatically through the GUI API, enabling custom scripts and integrations to automatically share call data with third-party CALEA compliance systems after calls end.
How It Works =
The CALEA compliance workflow using VoIPmonitor follows this pattern:
1. Recording: VoIPmonitor captures SIP/RTP traffic and stores PCAP files and audio recordings to disk. 2. API Access': The GUI API (`php/api.php`) provides programmatic access to retrieve call data. 3. Third-Party Integration: Custom scripts or middleware retrieve recordings via the API and forward them to CALEA-compliant third-party systems. 4. Automation': The entire process can be automated to run on a schedule (e.g., daily export of all completed calls).
API Methods for CALEA Export =
The following API methods are typically used for CALEA integrations:
- getPCAP - Retrieves full packet capture for a specific call (includes SIP signaling and RTP streams)
- getVoiceRecording - Generates and downloads audio recordings (WAV/OGG) for specific calls
- getVoipCalls - Queries the CDR database to get a list of calls matching criteria (e.g., date range, phone numbers)

Example CALEA Export Workflow =
A typical script for CALEA compliance would:
1. Query the CDR database via API to retrieve calls within a specified time window
2. For each call, download the PCAP file using getPCAP
3. Download the audio recording using getVoiceRecording
4. Forward the files to the third-party CALEA compliance system via HTTP/SFTP/other protocol
5. Log successful transfers for audit purposes
The API documentation mentioned above provides complete PHP script examples for bulk downloads that can be adapted for CALEA integration.
Important Notes =
- VolPmonitor does not provide built-in CALEA compliance software - it provides the raw call data that can be integrated with CALEA systems via its API
- The specific integration details depend on the third-party CALEA vendor's requirements (file formats, transfer protocols, metadata formats, etc.)
- Custom development or scripting is required to connect VoIPmonitor to third-party CALEA systems
- Audit logs showing which calls were exported and when should be maintained separately by the integration script or third-party system

AI Summary for RAG
Summary: VoIPmonitor supports CALEA compliance by providing programmatic access to recorded call data via its GUI API. The system records SIP/RTP streams (PCAP + audio), which can be retrieved through API methods (getPCAP, getVoiceRecording, getVoipCalls) and forwarded to third-party CALEA compliance systems. Custom scripts or middleware handle the automation and integration with specific CALEA vendors.
