Its the base that is the issue.
Its a new setup that acts as an extension of a pre-existing rasPBX system I use for my international work/travel.
I suspect it has to do with a voicemail bug I read about. I have reset the base and disabled voicemail, network mail on the phone. Next I will disable MWI VMWI in the obi device and hopefully get to the bottom of it. Obviously this is a unique dilemma but if I resolve it I will post what I find.
