How does StartACall encrypt browser calls?

StartACall uses standard WebRTC encryption for media DTLS SRTP and TLS for signaling between the browser and our cloud media gateways.

Is the call end to end encrypted when calling a regular phone number?

When bridging to the public phone network the audio leaves the encrypted WebRTC session at the gateway and continues on carrier networks. For browser to browser calls within StartACall the encrypted path can be maintained end to end.

Can I record encrypted calls?

Yes recordings are optional and stored encrypted at rest with access controlled by account permissions.

Do I need to install software?

No. StartACall works entirely in the web browser. Grant microphone permission and start calling without installing apps.

How are browser calls encrypted?

StartACall uses WebRTC which secures media with DTLS SRTP and secures signaling with TLS. This protects audio in transit between the browser and our cloud services.

Is encryption end to end when calling a phone number on the PSTN?

Media is encrypted between your browser and StartACall Twilio media gateways. When a call is bridged to the PSTN the audio leaves the encrypted WebRTC session and is handed to carrier networks which do not support end to end encryption. For browser to browser calls within StartACall encryption can be maintained end to end.

Can I record secure calls?

Yes. Call recording is optional. Recordings are stored encrypted at rest and access is controlled by account permissions. You can enable or disable recording per call or by policy for your account.

Encrypted Browser Calls

from Your Browser

Make secure phone calls directly from Chrome Safari or Firefox without installing apps. StartACall protects audio in transit with industry standard WebRTC encryption and gives you controls for recordings and compliance.

Learn How It Works

Secure DialerEncrypted

Calls use WebRTC encryption for media and TLS for signaling. When bridging to the public phone network encryption to the PSTN gateway is maintained but the call continues on carrier networks.

How Encrypted Browser Calls Work

A concise technical overview so you can trust the call path and protections for your audio and metadata.

Browser Security

We rely on browser WebRTC foundations which implement DTLS SRTP for encrypted media and TLS for signaling to our servers.

Cloud Media Gateways

Media is encrypted to StartACall and our Twilio backbone. For PSTN calls the gateway decrypts and forwards audio to carriers while maintaining secure links to the cloud.

Controls and Compliance

Enable or disable recording set retention policies and control access with role based permissions. Recordings and metadata are encrypted at rest.

When end to end encryption is possible

If both parties are on StartACall web clients the audio path can remain encrypted end to end. Bridging to external phone numbers involves carrier networks and changes the security model. We surface clear indicators in the UI so you always know the protection level of each call.

Key management

Secure keys and session negotiation managed by the browser and our services.

Proven protocols

DTLS SRTP for media and TLS for signaling are used end to end.

Security Features

Enterprise controls to protect voice privacy and meet internal policies.

Transport Encryption

DTLS SRTP and TLS protect your audio and signaling traffic between the browser and cloud.

Encrypted Storage

Recordings and logs are encrypted at rest and access is restricted by roles and permissions.

Access Controls

Granular user and team permissions with audit logs for every call and recording.

Real Time Monitoring

Track active calls connection status and media metrics to detect anomalies quickly.

Frequently Asked Questions

What encryption does StartACall use?

StartACall uses standard WebRTC encryption: DTLS SRTP for media and TLS for signaling. These protocols protect audio while it travels between the browser and our cloud services.

Is a browser call truly end to end encrypted?

When both parties are connected through StartACall web clients the audio path remains encrypted end to end. When a call is bridged to the PSTN the audio exits the encrypted session at the gateway and continues on carrier networks.

Can I control recordings and retention?

Yes. Recording is optional. Administrators can enable or disable recording configure retention windows and control who can access stored recordings.

Which browsers are supported?

StartACall supports the latest versions of Chrome Safari and Firefox on desktop and mobile where WebRTC is available. For best results keep your browser updated.
