8128 SIP Strobe Light (G2)
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.
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 8128 SIP Strobe Light will re-register
with the SIP server. Default setting is 3600 seconds (1 hour). Only change if
instructed otherwise.
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 8128 SIP Strobe Light will
attempt to register with the primary server but switch to a secondary server if
necessary. The configuration allows re-registration to the primary server upon
availability or to stay with a server until unresponsive.
Backup Server #1
Only visible if ‘Server Redundancy Feature’ is enabled. If primary server is
unreachable the 8128 SIP Strobe Light will attempt to register with the backup
servers. If enabled, the 8128 will always attempt to register with the highest priority
server.
Backup Server #2
Only visible if ‘Server Redundancy Feature’ is enabled. If backup server #1 is
unreachable the 8128 SIP Strobe Light will attempt to register with the 2nd
