Configuring SRTP
To prevent anyone from listening in to VoIP conversations, you can encrypt these connections.
The connection setup and termination, and also signalling, are encrypted with SIPS. The call
data is encrypted with SRTP.
Important: If you are using this on an Auerswald PBX, the PBX specifies the
encryption method. The PBX overwrites manual settings.
You can configure SRTP as follows:
