The idea with the softphone is more for an individual account. Each user will have its own account on the softphone.
A user could own a number of OBi devices, and if the user wants to share with others, just invite to the CoT.
So ideally, the most expert user can "own" all the OBi devices, and invite others who only have softphones to the CoT.
The OBi devices could live all around the world - in Australia, China, India, Spain, USA. OBiTALK will connect them accordingly.
