Digit Manipulation is the process of modifying the called or calling party number. It can be configured in a number of different ways:
- Route Pattern
- Route Group Level
- Translation Pattern
- Translation Rules in VGW
The specific types of manipulatios are :
- Calling Party’s Extenal Phone Mask
- Calling Party Transform Mask
- Prefix Digits
- Discard Digits Instructions(DDI)
- Called Party Transform Mask
Although Digit Manipulation canbe done within a Route Group, it is applied when the the Route Groups are added to the Route List.
Recall also as seen in a previous post, that when digit manipulations are configured at both the Route Pattern and Route Group level, the manipulation configured at the Route Group level has priority over that configured at the Route Pattern level because it is processed later.
Translation patterns can be used also to manipulate the calling or called party numbers prior to call routing. It can be also used to modify elements such as CSS.
