"Screen Calls by requesting caller name using an IVR" doesnt work

[jroozee]

I tried checking the box for "Screen Calls by requesting caller name using an IVR" for an extension under options, but it has no effect.
Am I doing something wrong?

Read an explanation of the feature here. It is to be used in conjunction with Rebound.
