Internal Calls showing extension instead of name

We have a PBX we replaced for a customer that was using a really old version of PBX in a flash with the old Aastra modules. When they called between the phones, the phones would “translate” the extension into a Name. The new system we put in is a FreePBX Distro with the System Builder Basic module set. Is there a way to restore the functionality of the name rather than the extension? for example Extension 345 (mary) calls extension 456 (John). Mary would show she is calling John once she dialed. But now (with the new system) Mary’s phone only says 456.

Thanks in advance,

I believe this is a “Send RPID” setting under the Advanced settings of the Extension.
