Parameter Description
Enable hang-up timer
for incoming calls
If you want LARA to hang up an incoming connection, you have
to check this box. The time out value is configured using the
next option.
Hang-up timeout The hang-up time out measured in seconds. Normally it is valid
for outgoing connections only. That means, in case LARA is
configured for callback.
In case the ‘Enable hang-up timer for incoming calls’ option is
checked, the time out will apply for incoming calls also.
IP address range Addresses from this range will be assigned to LARA and the
console computer during establishing an ISDN connection. The
first address will be used for LARA itself. The range must enclose
3 addresses at least.
Enable callback This enables the callback mechanism. If you have callback en-
tries configured (see below) LARA will reject any call from the
configured number(s) and make a call to a number, which can
be configured too.
Force callback Only callback connections are enabled if you enable this option.
That means nobody can dial in without callback. This option
has effect only if you have callbacks enabled.
Calling # This is the calling number - the client that tries to dial into
LARA.
Called # If you want to call the caller back, you have to enter his number
here.
User / Password If LARA calls back these are the user name and the correspond-
ing password for authentication on the console computer.
Call back after [x] sec-
onds The entry is marked as a callback entry in case this checkbox is
checked. Additionally, the delay, after which the callback con-
nection will be established, can be configured. Callback entries
are only effective when the callback mechanism is enabled.
In the following, we will present some example use cases for a proper ISDN configuration.
I want to allow non-callback dial in for everyone.
To achieve this you have to switch off the ”Force callback” option and you should have no callback
entries configured.
I want to allow non-callback dial in for selected people.
First, make sure ”Force callback” is switched off. Second, you have to make an entry with the
calling number for every allowed client. The other fields should be left empty. There must be at
least one non-callback entry or anyone can dial in!
