Hello Mattias,
Again I am unsure who TDC are and if they can open a support ticket.
I already outlined who you should be working with and they can open a ticket with Polycom support for you.
This is a software issue and if we can get your currently used configuration we can replicate and if needed fix this.
Please work with WESTCON GROUP EUROPEAN OPERATIONS LTD or force TDC to contact WESTCON GROUP EUROPEAN OPERATIONS LTD as a RMA and using the same configuration is causing this.
Best Regards
Steffen Baier
