Encrypting SIP and RTP Communication
SIP signalling is secured by setting 'SIP Transportation' to 'TLS' (under the Advanced Settings → Advanced SIP tab).
Setting it to 'TLS' ensures that the SIP traffic will be encrypted. The SIP signalling is responsible for establishing the call
(the control signals to start and end the call with the other party), but it does not contain the audio.
For the audio (voice) path, use the setting 'SDP SRTP Offer'. Setting this to 'Optional', means the SIP call's RTP audio
data will be encrypted (using SRTP) if the other party also supports audio encryption. If the other party does not
support SRTP, then the call will still proceed, but with unencrypted audio. To make audio encryption mandatory for all
calls, set 'SDP SRTP Offer' to 'Standard'. In this case, if the other party does not support audio encryption, then the
call attempt will be rejected.
