I just realized we may be out of luck. I remembered with Phonemail the 9006 uses an SLMS card, so maybe out of band digit recognition isn't possible with 2 SLMR channels. I could probably set up individual voicemail access channels by connecting an analog line into a trunk port dedicated to the voicemail access extensions. There's also an AMO I don't have access to with my rsca login, I think it's PURFT. That would display whether the Phonemail option is enabled, if that's required.
