Depends on the phone system and the carrier. On a Nortel Norstar with multiple PRI T-1s I use to admin the number displayed was the main office/billing number. They started another company and wanted a different number displayed for the new company. Called the LEC and had them make sure it passed the numbers displayed from our Norstar. Went to the phones of the new company and programmed the number they wanted to be displayed. So in this case I think it could have been any number I wanted.

I wouldnt say it could be "anything". IIRC, if your equipment is incapable of sending ANI [1] or it isnt properly communicated outward, then your LEC [2] provides the BTN [3] off the primary line; which is typically the main business number for the account. 1.

This is especially true for those using an ISDN PRI from a telco. The phone number that shows up on caller ID is set by the phone system that originated the call (or sometimes the telco themselves). That number could be anything at all. Most typically they are either set to be the company's main line or the direct dial number for the extension.
