The Translation Pattern to match the Calling Number

The translation pattern is the most important tool in the Call Routing Process on Cisco Unified Communication manager.

By definition a Translation Pattern is used to match the DIALED NUMBER (CALLED). After a match is found we perform a digits manipulation.

But what if we want to match based on the CALLING NUMBER?

Yes it’s possible by using the “Route Next Hop By Calling Party Number” option in the translation pattern configuration.

Finally a Translation Pattern can be used to match both the Calling / Called Numbers. But only if the translation pattern with dialed number is matched first and we instruct it to match the next translation pattern based on the calling number.

There are so many scenarios, we can use the translation pattern, we can write a book about this attractive tool.
