This table is displayed in three columns that are edited the same way as the first
table, except that there is no special editing as in the second column of the first table.
3.3.4.3 Callback Table and special routing
The last table on this page, which is only activated if there is a valid Basic Pro license
(see 3.3.15), allows to call back special GSM numbers on request. The callback can
be initiated either by a call (which is rejected) or by an SMS, depending on which
method is allowed in the columns “Call“ and “SMS“ by entering “yes“. If a callback by
SMS is allowed, it is sufficient to receive an SMS from that GSM number. If the SMS
contains a number, it is stored as desired number to be called.
If the callback is accepted by the GSM user, he usually gets a dial tone and can dial
a number to one of the allowed destinations. If the channel used does not allow
dialling (“Call Default“), there is no dial tone and the call is forwarded to the number
configured in column “Forward to“. If the callback was done due to a received SMS
and the SMS contained a number, there is no dial tone either and that number is
called.
If one (and only one) line has an empty “Calling Number“, this line matches any call
without CLIP. These callers never get a dial tone but are always forwarded to the
number configured in column “Forward to“.
This table can also be used to configure a default number different from that in the
channel settings. The number configured in column “Forward to“ supersedes the
number of the channel settings and is called if that special GSM user is calling and
nothing is dialled or dialling is not allowed. This is also true if no callback is allowed,
so that the entry only assigns a different default number.
Additionally, the table can prevent certain callers from calling specific destinations. If
a calling party number matches an entry in the callback table, those destinations in
the routing table not allowed by this entry are removed from the possible routes.
3.3.4.4 Automatically inserted country and area codes
The own country and area code is programmable on the dialog page named “ISDN
Cfg“. This enables the router to find matches in the tables even if the table entries are
specified with these codes and called numbers are lacking them. It is also possible to
specify the tables without these codes and called numbers with these codes will still
match. This eliminates the need for specifying all possible number representations.
