Algo 8190S User Manual page 45

Register Period (seconds)
Maximum requested period of time where the 8190S 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 the 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.
