Soundstation 2Ex and SoundStation 2W



i ordered 2 external microphones for our soundstation 2 expandable.

But if i connect the microphones to the soundstation, most opf the bhuttons stop working and i cant call anyone.


We are using the following products (A Polycom Support Technician already told me that the devices should be compatible...)


Soundstation Part No.



Microphone Part No.



Are these 2 devices compatible?


Kind regards
