SoundStation 2W Register

I have the Sound station 2W matching console and base(serial numbers are the same). I have tried to upgrade the firmware by following the perscribed method. I am getting an error message Upgrade was NOT successful. Close the application and restart the upgrade process. When I go to this phone in the menu and check the versions I see CVM:UNAVAILABLE, DSP:S2W.CON.01.605, CPLD:1.06. When I try to exit from this screen, it is frozen. I have to manually reboot.

Re: SoundStation 2W Register

Hello 56willys,

welcome to the Polycom Community.


Once the SoundStation2W unit shows the CVM as unknown and/or toggles between unknown and a value the Unit cannot be recovered in the field and you need to raise an RMA via your reseller or call Polycom support.

Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.

Best Regards
