SIP Setting
SIP is a request-response protocol, dealing with requests from clients and responses
from servers. Participants are identified by SIP URLs. Requests can be sent through
any transport protocol. SIP determines the end system to be used for the session,
the communication media and media parameters, and the called party's desire to
engage in the communication. Once these are assured, SIP establishes call
parameters at either end of the communication, and handles call transfer and
termination.
Emergency Routine
This functionality is only working if S
I
P is configured, and helps to monitor the
Satellite Modem synchronisation without traffic consumption, because of monitoring
the SIP re-registration. If SIP is not registered, the router takes some actions to get
the Satellite Modem synchronisation back.
