titleAD Wild Cards

 

Note SBC supports the use of wild cards. This means that you can do partial matching in AD fields. The following is an example of how the =telephoneNumber= field is used to forward an inbound call to the user's new extension.

Scenario

Someone dials extension 3633, the four digits are added to the Area Code and prefix as well as the wildcard character, the result (User Value 1) is used in an AD query against the =telephoneNumber= field. The contents of the first =telephoneNumber= field containing the match string is then parsed for the last four digits, which are output from the transformation.
