Unified 4.0(4)SR1 w/ failover integrated with CCM 4.0(2a)SR2b. I'm creating Directory Handlers for each remote location and limiting the search via PDLs. Being unified, there are a large number of PDLs that aren't pertinent to Unity. The DH dialog for searching for a DL contains only the domain and not any specific DL name searching criteria. Is there an undocumented way to reduce the number of DLs displayed?
No, the PDL search mechanism is pretty wide open in the SA to accomodate all kinds of deployments.
However you can simplify things a big using the Audio Text Manager - it has a different search dialog that will let you filter by display name (or extension if you've assigned them to PDLs) and sort by alias, name and extension which will help you find the list you're looking for much more quickly.
AST is installed on your box and is available in the Tools Depot - you can also find the latest version of it on its home page here:
Go to the "Grid View" tab, select directory handlers, choose your handler and then on the "Search Options" tab you can select the DL using the "Set" button...
