Secure VoIP Call Recording: Store Audio in Encrypted Files

As VoIP technology continues to power modern communications, data privacy and call recording security have become mission-critical, especially in industries like healthcare, finance, and customer service. With VaxVoIP SIP Recording SDK, you can record VoIP calls in real-time and securely store the audio data in encrypted files, ensuring full compliance with data protection standards.

Why Secure Call Recording Matters

When recording VoIP calls, storing the audio data in plain formats can expose sensitive information. Secure environments require encryption to protect:

• Customer financial details
• Healthcare conversations (HIPAA compliance)
• Legal or regulatory communications
• Confidential internal meetings

Encrypting recordings ensures that unauthorized users cannot access the contents even if they gain access to the file storage.

VaxVoIP SIP Recording SDK: Real-Time Recording with End-to-End Security

The VaxVoIP SIP Recording SDK allows developers and businesses to:

• Record VoIP calls in real time
• Access raw PCM audio data for processing
• Store recordings as AES or RSA encrypted files
• Choose between server-side encryption or client-controlled encryption

Whether you're running a contact center, PBX system, or VoIP gateway, you can integrate encrypted call recording into your infrastructure with ease.

How Encrypted Recording Works

Access PCM Audio

Using the SDK’s recording events, you can access real-time PCM audio data of the VoIP call. This allows you to immediately begin encryption and storage without waiting for the call to end.

Encrypt the Audio Data

You can integrate any encryption method of your choice, including AES-256 for symmetric encryption, RSA-2048 for public/private key encryption, or client-supplied keys for multi-tenant environments.

Store or Upload the Encrypted File

Encrypted files can be stored locally or uploaded to secure cloud storage. You can also tag metadata, integrate with CRMs, and customize key management per client or department.

Multi-Tenant Encryption Support

The SDK supports tenant-specific encryption. Clients can supply their own keys, ensuring their audio remains private—even from the host system. This is ideal for white-label platforms or compliance-driven deployments.
