8028 SIP Doorphone (G2) FW 3.2
SIPS Scheme
Only visible when ‘SIP Transportation’ set to ‘TLS’ or ’Auto’. Enabling SIPS Scheme
requires the SIP connection from endpoint to endpoint to be secure.
Validate Server Certificate
Enable this option to validate the SIP server against common certificate authorities. To
validate against additional certificates, use the System > File Manager tab to upload a
Base64 encoded X.509 certificate file in .pem, .cer, or .crt format to the 'certs/trusted'
folder.
Force Secure TLS Version
Enable this option to require TLS connections to use TLSv1.2.
SIP Outbound Support (RFC 5626)
Enable this option to support best networking practices according to RFC 5626. This
option should generally be enabled if the Algo device is being registered with a hosted
server or if TLS is being used for SIP Transportation.
Outbound Proxy
IP address for outbound proxy. A proxy (server) stands between a private network and the
internet.
Register Period (seconds)
Maximum requested period of time where the 8028 SIP Doorphone will re-register with the
SIP server. Default setting is 3600 seconds (1 hour). Only change if instructed otherwise.
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.
Media NAT
IP address for STUN server if present or IP address/credentials for a TURN server.
Server Redundancy Feature
Two secondary SIP servers may be configured. The 8028 Doorphone will attempt to
register with the primary server but switch to a secondary server when necessary. The
configuration allows re-registration to the primary server upon availability or to stay with a
server until unresponsive.
If Server Redundancy is selected the web page will expand as shown below.
