Backup SIP Server
The
Backup registration allowed
flag indicates whether or not the phone treats the backup
proxy server as a SIP registrar. If set to "Yes", the phone tries to register its SIP address with
the server whose IP address or hostname is specified by
Backup proxy address
. Once an IP
address has been entered, the SIP-UDP Port is opened, even if SIP-TLS is used for the OS
Voice connection.
The
Backup registration timer
determines the duration of a registration with the backup SIP
server.
The
Backup transport
option displays the current transport protocol used to carry SIP mes-
sages to the Backup proxy server.
The
Backup OBP flag
indicates whether or not the Backup proxy server is used as an out-
bound proxy.
