Advanced Settings Tab – Advanced SIP
SIP Transportation
Which transport layer protocol to use for SIP messages. Setting 'SIP Transportation' to
'TLS', ensures the encryption of SIP traffic.
SIPS Scheme
Only visible when 'SIP Transportation' set to 'TLS'. Enabling SIPS Scheme requires the
SIP connection from endpoint to endpoint to be secure.
SDP SRTP Offer
Setting 'SDP SRTP Offer' to 'Optional', means the SIP call's RTP data will be left
unencrypted if the other party does not support SRTP. Setting 'SDP SRTP Offer' to
'Standard', encrypts RTP voice data, meaning the normal audio RTP packets will now be
secure (SRTP). This means SIP calls will be rejected if other party does not support
SRTP. The 'Standard' option secures the audio data between parties, by making sure that
it's not left out in the open for third parties to later reconstruct and listen to.
