Advanced numbers parameters translation on IMG 1004/ 1010

Introduction: 

When integrating with SS7 networks, there may be requirements to translate (override) the values of the parameters in dialed/called number, originating/calling number, generic number, and so on, in ISUP messages. The Dialogic® IMG 1004 Integrated Media Gateway and Dialogic® IMG 1010 Integrated Media Gateway support the translation of these parameters in addition to the digit translations.

Advanced Number Translations under a Translation Table Entry are only performed when that particular Translation Table Entry matches. If the "Re-run option" is set on that Translation Table Entry in order to also translate a different number type, then any Advanced Number Translations configured under the subsequently matched Translation Table Entry will be also performed.

Advanced Dialed number translation objects and parameters are listed below:

1- Advanced Dialed Number Translation

The following parameters can be translated using "Advanced Dialed Number translation" in Dialed (called) number:
- Nature of Address
- Numbering Plan
- Internal Network Number Indicator (INN)

Configuration in Client View:

Dialogic IMG EMS -> Routing Configuration -> Incoming Translation Tables -> Translation Table -> Translation Entry -> New Advanced Dialed Number Translation

2- Advanced Originating Number Translation

The following parameters can be translated in Originating (calling) numbers using "Advanced Originating Number Translation":
- Nature of Address
- Numbering Plan
- Calling Party Category
- Number Incomplete Indicator
- Screening Indicator
- Presentation Indicator
- SI/PI Priority

Configuration in Client View:

Dialogic IMG EMS > New Routing Configuration > New Incoming Translation Tables > New Incoming Translation Table > New Translation Entry > New Advanced Originating Number Translation. 

3- Advanced Generic Number Translation

The following parameters can be translated in Generic Number using "Advanced Generic Number Translation":

- Number Qualifier Indicator (ITU Only)
- Nature of Address
- Numbering Plan
- Numbering Incomplete Indicator (ITU Only)
- Screening Indicator (ITU Only)
- Presentation Indicator

Configuration in Client View:

Dialogic IMG EMS -> Routing Configuration -> Incoming Translation Tables -> Translation Table -> Translation Entry -> New Advanced Generic Number Translation

4- Advanced Billing Number Translation

The following parameters can be translated in Billing Number using "Advanced Billing Number Translation":

- Nature of Address
- Numbering Plan
- Internal Network Number Indicator (INN)

Configuration in Client View:

Dialogic IMG EMS -> Routing Configuration -> Incoming Translation Tables -> Translation Table -> Translation Entry  -> Advanced Billing Number Translation

5- Advanced Carrier Number Translation

The following parameters can be translated in Carrier Number using "Advanced Carrier Number Translation":

- Type of Network
- Network Identification Plan
- Circuit Code

Configuration in Client View:

Dialogic IMG EMS -> Routing Configuration -> Incoming Translation Tables -> Translation Table -> Translation Entry  -> New Advanced Carrier Number Translation

Notes:

• The  parameters in "Advanced number translation" objects are all set to "No translation" by default when the objects are first created. Each parameter value can be selected from the drop-down list depending on the required values for the SS7 network. For example, the "NOA" parameter in "Advanced Dialed Number Translation" can be set to "004- International Number" under a "Translation Entry" that has "00&" String for Dialed number.
• If "Privacy" is enabled in a SIP profile and RPID header is received in an INVITE in a SIP to SS7 call, then SI and PI parameters in Originating Number can be only translated if "SI/PI Priority" setting is enabled.
