To set the ACN, you use a copy of which extension and configure its parameter?

• A. extension 70551
• B. extension 70550
• C. extension 70552
• D. extension 70560

Answer: (A)

In Epic, configuring something like ACN is done by duplicating a baseline extension that already contains the ACN parameter and then editing that parameter on the copy. This keeps the original extension intact while you adjust the setting in a testable, isolated copy.

The right starting point is the extension that has the ACN parameter built into its configuration, so you copy that one and set the value there. In this case, the template you use is the extension identified as 70551. The other extensions listed don’t carry the ACN parameter you need to configure, so they aren’t suitable starting points for setting ACN.
