Encrypted audio flow / SRTP

[tosI5-sysadmins]

Hello,
I'd like some kind of confirmation.
Is Audio flow encrypted when using 3CX app?
I remember in past (=previous version) I was able to decode audio in wireshark and I had to enable SRTP to ensure audio flow is encrypted.
I tried in v.20 but now seems different.

Is there anything official about this? Just for calls to 3CX app, calls sent to voip phones are unencrypted.
An official page would be nice for my CISO
Thanks

Hi,

The latest 3CX Apps use the 3CX Tunnel which encrypts the data via TLS/SRTP, and the webclient uses WebRTC which uses DTLS/SRTP by design.
