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. '?' 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 digit matches.

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.
