ISDN_CIRC_%_ROUTE_N='2'
ISDN_CIRC_%_ROUTE_1='192.168.8.0/24'
ISDN_CIRC_%_ROUTE_2='192.168.9.0/24'
All nets must have an explicit entry hence for each route a new ISDN_CIRC_x_ROUTE_y=”
line has to be provided.
For using fli4l’s LC routing features a default route can be assigned to *several* circuits.
Which circuit is used is driven by ISDN_CIRC_x_TIMES, see below.
ISDN_CIRC_x_DIALOUT ISDN_CIRC_x_DIALOUT specifies the telephone number to be dialed.
It is possible to put in several numbers (if one is busy the next is chosen) - numbers have
to be separated by blanks. A maximum of five numbers can be used.
ISDN_CIRC_x_DIALIN If the circuit (also) serves for dial-in ISDN_CIRC_x_DIALIN keeps the
phone number of the callee - with a region prefix but *without* a leading 0. Ports behind
telephone systems may have to specify one or even two zeros.
If more users should be able to dial in over a circuit more numbers may be added separated
by blanks. It is advised to assign a separate circuit for each caller although. Otherwise
two callers trying to dial in at the same time (which is absolutetely feasible with 2 ISDN
channels) could collide on behalf of IP addresses assigned.
If callers don’t transfer a number during calling ’0’ could be used. Caution: everyone
not transferring a number is allowed to call in then!
If number-independent dial-in should be realized set ’*’.
In both cases a separate authentification (see ISDN_CIRC_x_AUTH) is unavoidable.
ISDN_CIRC_x_CALLBACK Settings for callback, possible values:
’in’ fli4l is called and calls back
’out’ fli4l calls, hangs up and waits for callback
’off’ no callback
’cbcp’ callback control protocol
’cbcp0’ callback control protocol 0
’cbcp3’ callback control protocol 3
’cbcp6’ callback control protocol 6
CallBack control protocol (aka ’Microsoft CallBack’) cbcp6 is the protocol mostly used.
Default setting: ’off’
ISDN_CIRC_x_CBNUMBER Set a callback number for protocol cbcp, cbcp3 and cbcp6
here (mandatory for cbcp3).
ISDN_CIRC_x_CBDELAY This variable sets a delay in seconds to be waited until triggering
callback. The meaning differs depending on the direction of callback:
• ISDN_CIRC_x_CALLBACK=’in’:
If fli4l is called and should call back ISDN_CIRC_x_CBDELAY specifies the waiting time
until calling back. Use ISDN_CIRC_x_CBDELAY=’3’ as a rule of thumb. A lower value
may work and speed up connection establishment then depending on whom to call
back.
