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 unen-
crypted 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.
SIP Outbound Support (RFC 5626)
Enable this option to support best networking practices according to RFC 5626. This op-
tion should generally be enabled if the Algo device is being registered with a hosted server
or if TLS is being used for SIP Transportation.
