Reference:Administration/Relay/CGPN-Maps
The CGPN (Calling Party Number) can be changed with mappings entered here for a call sent thru the respective route. A headmatch of the received number is performed and the matching digits are replaced by the out digits. '.' at the end of the number can be used to match only if a certain number of digits was received and '?' can be used to match any digit.
If the call is received from an interface configured as Gatekeeper/Registrar, the mapping can be restricted to a certain registration.
On presentation restricted numbers can be matched and the presentation restrcited property of a calling party number can be set or cleared.
Configuration
GK Reg. Name
If configured, the mapping is applied only if the call is received from a Gatekeeper/Registrar interface and the name configured for the registration matches this name.
Number In
Digits used for the headmatch on the received number. In addition to the normal dialing digits (0..9,*,#) the following characters have special meaning:
| R | If 'R' is used as first digit of the number only numbers with 'presentation restricted' match. In this case the 'presentation restricted' property is cleared if 'R' is not used on 'Number Out'. |
| ? | Can be used at any place inside the number and means that any received digits matches. |
| . | May be used at the end of the number to indicate that after the matched digits more digits must be received to match. Digits matching to '.' are not removed from the number as the other matching digits. |
Number Out
The matching digits are replaced by this number. A 'R' as first character means that the 'presentation restricted' property will be set for the calling party nuumber.
