Got a weird one. MiVoice Business Express running 8.0.2.301. Calls dialed through the auto attendant (NuPoint Callflow) to a user will not display correct calling number data, or ring the EHDU (cell phone) more than 1 ring unless the user's desk phone is present in their MDUG. When desk phone is absent, the NuPoint port DN is displayed as the calling number in MiCollab, the EHDU only rings once, and then the call drops. If the desk phone is present, even if it's unplugged, everything works as it should. No active SWA, so I can't open a ticket with Mitel.
