YES!
If you have a mixture of SD Office and SD Pro and OfficeRunner/DW Pro units, they can intermingle!
You can conference in a DW Pro2 in a forest of SD Pros or SD Offices! You can put an SD Office Mic on an OfficeRunner base if you prefer a sleek black headset + a fancy blue cube-shaped base!
You can... you get the picture.
PS: Nothing from the D10 series will pair up to SD or OfficeRunner bases.
