I updated the firmware on my dad's device, and after that all the speed dial numbers got replaced with account-wide speed dials from ObiTalk admin panel (**9xxx matching the devices that I have).
To make it worse, now these values get overwritten every time provisioning happen. So the only way to make them stick is to disable auto provisioning. I know - RonR will say that I shouldn't enable auto-provisioning in the first place ;) - but these values were not overwritten before.
Is it a bug? for variety of reasons disabling auto provisioning will make things very inconvenient for me ::)
Note - it didn't wipe out anything on another adapter... weird!
