Chapter 5. Setting up a SMS Gateway
Description
If set, only connections from
these IP addresses are accepted
to receive-port. TCP/IP
connection only.
If this option is set to a value
larger than 0, then the connection
will be closed after the
configured amount of seconds
without activity. This option
interacts with the
keepalive
configuration option. If
is smaller than
keepalive
, then the
idle-timeout
connection will never be idle and
those this option has no effect. If
is larger than
keepalive
, than
idle-timeout
reopens the
keepalive
connection. This allows one to
poll for pending mobile
originated Short Messages at the
SMSC.
A keepalive command will be
sent to the SMSC connection this
many seconds after the last
message. The right value to use
depends on how eager the SMSC
is to close idle connections. 50
seconds is a good guess. If you
see many unexplained
reconnects, try lowering this
value. Set it to 0 to disable this
feature. Requires username or
my-number to be set.
A message is resent if the
acknowledge from SMSC takes
more than this time. Defaults to
60 seconds.
