For calls from ISDN1, delete the first two digits of the calling numbers that start with the prefix 88.
The TDM 1 rule is as follows:
OutCDPN:C1S66/R1S71/InCPN:C1S88/D1S2
Description
In this rule, OutCDPN:C1S66/R1S71 is used to operate the called numbers of calls to ISDN1.
If the called number of a call is 6602, it conforms to the matching rule C1S66. Then, the substitution
rule R1S71 is applicable; that is, the called number 6602 is substituted by 7102.
In this rule, InCPN:C1S88/D1S2 is used to operate the calling numbers of calls from ISDN1.
If the calling number of a call is 88123, it conforms to the matching rule C1S88. Then, the deletion
rule D1S2 is applicable; that is, the first two digits of 88123 are deleted so that the calling number
88123 is translated to 123.
