I didn't ask or "cheat sheet". just asking for guidance to what areas of programming I need to enter data. Provisioning? routing? Targets, line access. Will all outgoing calls be done only from intercom? Just looking for general areas in programming I need to address. Thanks"
THAT is exactly what a 'cheat sheet" is!
Nortel (and most manufactures) did not create cheat sheets, only manuals.
As Curlycord pointed out you have to read the manual.
