You can configure translation patterns to manipulate digits for any type of call. Translation patterns follow the same general rules and use the same wildcards as route patterns. As with route patterns, you assign a translation pattern to a partition. However, when the dialed digits match the translation pattern, Cisco Unified Communications Manager does not route the call to an outside entity such as a gateway; instead, it performs the translation first and then routes the call again, this time using the calling search space configured within the translation pattern.
Translation Pattern Prerequisites
Before you configure a translation pattern, you must complete the following tasks:
For each translation pattern that you create, ensure that the combination of partition, route filter, and numbering plan is unique. If you receive an error that indicates duplicate entries, check the route pattern or hunt pilot, translation pattern, directory number, call park number, call pickup number, or meet-me number configuration windows.
Configure translation patterns to specify how to route a call after it is placed.
Configure Translation Patterns
Configure translation patterns to specify how to route a call after it is placed. Configuring translation patterns allows Cisco Unified Communications Manager to manipulate calling and called digits as appropriate. When the system identifies that a pattern match occurred, Cisco Unified Communications Manager uses the calling search space that is configured for the translation pattern to perform the subsequent match.
From Cisco Unified CM Administration, choose Call Routing > Translation Pattern.
Choose one of the following options:
To add a new translation pattern, click the Add New button.
To modify the settings for an existing translation pattern, enter the search criteria, click Find, and choose a translation pattern from the resulting list.
The Translation Pattern Configuration window appears.
Configure the fields on the Translation Pattern Configuration window. See the online help for more information about the fields and their configuration options.
