6.5.4. Routing
Port modes
CLIP
By activating this parameter you switch on the I
2
CR function
(Intelligent Incoming Call Routing). Every incoming call that
contains information about the subscriber number CLIP is
compared to numbers listed in the Clip Routing chart (see 0). If
there is a match, the incoming call is connected directly from the
given port to the port and number (MSN, ISDN number, or similar
terminal number) quoted in this chart. This parameter may be
activated regardless of other parameters.
DISA
DISA is a service that distributes incoming calls. All incoming
calls (except those mentioned in the “CLIP” section above)
are
answered and get a DISA message – to activate this function,
select the required parameters in the “Routing > General
parameters” section (see 6.5.4.1). You are
recommended to activate the Operator
service (see below) at the same time.
Operator 1, 2
Every incoming call (except those that are mentioned in the “CLIP“ and “DISA“ sections
above) is dialled directly to the number included in the “Routing > General parameters”
section (see 6.5.4.1). If you use this function together with the DISA service, every
incoming call will be forwarded to the operator (except for the “CLIP” section) that does
not tone-dial the DDI number – refer to DISA.
Number Normalising
If this parameter is activated, all calls are performed using complete numbers including
all normalised prefixes (+420 2 223344, e.g.). Respective prefixes must be correctly
filled in in the National and International Destination charts (see 6.5.4.2, 6.5.4.3). It is
particularly suitable for roaming activated in GSM networks.
CALLBACK
Global enable/disable of CALLBACK function on a selected GSM port. For right function
you have to activate function CLIP!
Auto CLIP routing
When this function is activated, the gateway begins to register information about outgoing
unconnected (connected) calls in to its local RAM memory. The following information is saved in
to the memory:
- The called number
- The calling number
- Date and time of the call
In the case that a number that had been previously dialed and registered in to the memory calls
back to the gateway within a configurable period of time, this call is routed to the subscriber who
last dialed the particular number. For this function to work properly, it is necessary to activate
CLIP. More information about the configuration of Auto CLIP routing can be found in section
6.5.4.1, on page 40.
