Hello,
So, if you are calling any internal point to point call does your SX10 works properly?
If yes, that means problem is not with SX10 unit, and at some point of network is blocking the incoming media which you can isolate by taking logs and pcaps on all hops.
If no, then you need to try any other HDMI cable or any other monitor to see if the problem is with your cable or monitor or with codec?
Thanks
