8138 SIP Multicolor Strobe Light
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 8138 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 8138 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 8138 SIP Strobe Light will attempt to register with the backup servers. If enabled, the
8138 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 8138 SIP Strobe Light will attempt to register with the 2nd backup server. If enabled,
the 8138 will always attempt to register with the highest priority server.
