ALL SD HEADSETS DISCONTINUED! [OFFICERUNNER DISCONTINUED] [DW PRO1 DISCONTINUED] 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 OR bases. SO DON’T TRY IT! Thanks..
