Directory help

OK, I made a directory (Applications -> Directory) and seems to be all set up. Dumb question, how do I access it via the actual phones? What is the procedure / process so users can access the directory on their phone? I could not find any doc, if there sis ome, can you also point me to that. Thanks in advance.

Just bumping this in case there is a solution. In fact I’m not sure what the Asterisk Directory is really doing.

I think dialing 411 accesses the directory.
