You can only dial IDs of objects created in Unity. You can't just get the opening greeting and then go wild dialing digits and call the weather line in Japan or something...
Any call handler created with an ID or subscriber ID in the system can be dialed by an outside caller from the opening greeting if you haven't locked down the one key maps. If there are transfer rules configured on those handlers/subscribers Unity will dial those numbers (which can be external numbers, of course).
Folks that can make changes to the dialout numbers either over the phone, from the SA or via the AA are restricted by their Class of Service for which numbers they can enter into transfer fields. In this way you can restrict what numbers a subscriber can enter into their transfer number in the subscriber conversation... if you want to be really tight you can association subscribers with a COS that has a restriction table for transfers set to deny ANY number and then they couldn't change it. Only and admin with rights to do so could do it for them (i.e. folks manning a help desk... this is common in larger deployments).
Each COS has 3 seperate restriction tables (one for transfers, one for notification dialouts and one for fax delivery numbers). These dictate which numbers can be entered into a transfer field, NOT at dial time... whatever number is in the transfer field at the time it's accessed will be dialed. In this way admins can change transfer numbers for folks that are associated with restrictive COSes that don't allow for such things and the transfers still work OK.
If you want to, you can lock down all the one key dials in the opening greeting and/or every handler in an audio text tree such that users can only hit one keys and not dial IDs of call handlers or subscribers directly. If you're really paranoid about making sure outside callers go only where you want them to, this is the way to do it.

The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
