of the calling numbers is made according to the CGPN maps specified for ISDN interfaces
or gateways, if available.
Enable “Exclude from Auto-CGPN” check box if you want certain routes to be excluded
from this process.
21.5 Selective Routes Depending on the Calling Number
In certain cases it can be useful to restrict individual routes to particular calling numbers. In
this way, access to a chargeable exchange line, for example, can be restricted to certain
extensions (selective class of service).
Proceed here as follows:
1 In Gateway > Routes, select the entry that you want to restrict.
2 Select the “Verify CGPN” check box.
3 Click on the Insert Map symbol, see figure 73 on page 94. A new window opens.

4In the Number in field type the common prefix that you wish to allow for this route.
In this case it does not make any sense to make no entries.
5In the Number out field type the sequence of digits that is to replace the prefix
entered above. It usually does not make any sense to make any replacements here.
The same sequence of digits is then specified as in the Number in field.
6 Leave the remaining fields empty.
If you have set automatic correction of all calling numbers (see section 21.4 Automatic
Correction of all Calling Numbers on page 146) the check applies to numbers already
corrected.
Note: If you delete the CGPN Maps, make absolutely certain that you clear the “Verify
CGPN” check box, since otherwise no calling number at all would be allowed, making the
Map ineffective.
21.6 Change the Calling Party Number for Specific Routes
In some case it can be useful to modify the calling party numbers for calls routed with the
aid of specific Maps. Proceed here in accordance with the relevant descriptions under
section 21.3 Manipulation of a Calling Number (CLI) on page 146.
