TAU-4M.IP Subscriber gateway
In the 'homing' mode, three types of the main SIP-proxy management are available: periodic
transmission of OPTIONS messages to its address, periodic transmission of REGISTER messages to its
address, or transmission of INVITE request when performing outgoing call. First of all, INVITE request
is sent to the main SIP-proxy, and if it is unavailable, then to the next redundant one, etc. Regardless
of the management type, when the main SIP-proxy operation is restored, gateway will renew its
registration. Gateway begin operation with the main SIP-proxy.
