this is CME 7.0 running on 2851, trying to allow users to edit their own speed dials via phone UI ( or web if possible), having trouble with it. followed the CME sys admin guides, but in the directory menu of the phone, it still doesn't show the speed dial editing option. I am testing with a CIPC because I don't have physical access to the phones. could this be the issue? if not, what are the essential steps to achieve it?
