Number Translation Configuration

To create a translation rule:

In Superuser mode, type configure terminal and press Enter.
```
ORACLE# configure terminal
```
Type session-router and press Enter to access the session router configuration elements.
```
ORACLE(configure)# session-router
```
Type translation-rules and press Enter. The system prompt changes to let you know that you can begin configuring individual parameters.
```
ORACLE(session-router)# translation-rules
ORACLE(translation-rules)#
```
From this point, you can configure translation rules parameters. To view all translation rules parameters, enter a ? at the system prompt. The following is an example of what a translation rule configuration might look like. Parameters not described in this section are omitted below.
```
translation-rules
        id                             addplus1
        type                           add
        add-string                     +1
        add-index                      0
        delete-string
        delete-index                   0
```

Translation Rules

Set the following parameters to configure a translation rule:

ID—Set a descriptive ID name for this translation rule.
type—Set the type of translation rule you want to configure. The default value is none. The valid values are:
- add—Adds a character or string of characters to the address
- delete—Deletes a character or string of characters from the address
- replace—Replaces a character or string of characters within the address
- none—Translation rule is disabled
add-string—Enter the string to be added during address translation to the original address. The value in this field should always be a real value; i.e., this field should not be populated with at-signs (@) or dollar-signs ($). The default value is a blank string.
add-index—Enter the position, 0 being the left most position, where you want to add the string defined in the add-string parameter. The default value is zero (0). The valid range is:
- Minimum—0
- Maximum—999999999
delete-string—Enter the string to be deleted from the original address during address translation. Unspecified characters are denoted by the at-sign symbol (@).

The @ character only works if the type parameter is set to delete. This parameter supports wildcard characters or digits only. For example, valid entries are: delete-string=@@@@@, or delete-string=123456. An invalid entry is delete-string=123@@@. When the type is set to replace, this value is used in conjunction with the add-string value. The value specified in the delete-string field is deleted and the value specified in the add-string field is inserted. If no value is specified in the delete-string parameter and the type field is set to replace, then nothing will be inserted into the address. The default value is a blank string.
delete-index—Enter the position, 0 being the left most spot, where you want to delete the string defined in the delete-string parameter. This parameter is only used if the delete-string parameter is set to one or more at-signs. The default value is zero (0). The valid range is:
- Minimum—0
- Maximum—999999999

Session Translation

To configure session translations:

Exit out of the translation rules element and enter the session translation element.
```
ORACLE(translation-rules)# exit
ORACLE(session-router)# session-translation
ORACLE(session-translation)#
```
From this point, you can configure the session translation element. To view all session translation parameters, enter a ? at the system prompt. The following is an example of what a session translation configuration might look like:
```
session-translation
        id                             lrules-out
        rules-calling                  rule1 rule2 rule3
        rules-called                   addplus1
```
ID—Set a descriptive ID name for this session translation.
rules-calling—Enter the rules calling in the order in which they should be applied. Multiple rules should be included in quotes and separated by spaces.
```
ORACLE(session-translation)# rules-calling "rule1 rule2 rule3"
```
rules-called—Enter the rules called in the order in which they should be applied. Multiple rules should be included in quotes and separated by spaces.

Number Translation Application

To complete your number translation configuration, you must enter into a realm-config or session-agent element and assign session-translations there.

Navigate to the chosen element.
- To move from the session-translation element to the session-agent element, exit out of the session translation element and enter the session agent element.
```
ORACLE(session-translation)# exit
ORACLE(session-router)# session-agent
ORACLE(session-agent)#
```
- To move from the session-translation element to the realm-config element, exit from the session translation element to the configuration path.
```
ORACLE(session-translation)# exit
ORACLE(session-router)# exit
```
  Navigate to the ream-config element located in the media-manager path.
```
ORACLE(configure)# media-manager
ORACLE(media-manager)# realm-config
ORACLE(realm-config)#
```
In both realm-config or session agent elements, you must specify an in-translationid and/or an out-translationid in order to configure the number translation.
```
session-agent
        in-translationid
        out-translationid              lrules-out
realm-config
        in-translationid
        out-translationid              lrules-out
```
Set the following parameters to configure a translation rule:
- in-translationid—Enter the configured session translation that you want to affect the incoming traffic in this parameter.
- out-translationid—Enter the configured session translation that you want to affect the outgoing traffic in this parameter.
