On my mitel sx- 50 a room is lock how do I unlock it?

SOURCE: CALLER ID

Negative, the SX 50 does not support CID. You can upgrade the Mitel or use a CID Multi line interface to a PC. Here is one such model.

SOURCE: Our phone won't allow us to call 866 numbers

It's in a table of allowed numbers. If you're familiar with the system, you ought to be able to find where 800 and 888 are allowed. Just add 877,866 and 855 as entries.

If ARS is implemented, you'll find your entry in the 700 table, maybe :-)
I don't envy you if that is the case.

Your Wake up device is in DND.... it either didn't hang up or it didn't answer. You should contact your vendor to have them check the RAD (Recorded Announcement Device).
Unless you know the extension number associated with it (the installers use different numbering from site to site and I couldn't even guess for you), you won't be able to clear the DND. If you do know the ext number... follow these instructions from the attendant console.
