Hello,

I'm receiving console warnings that the switch is receiving unsupported RTCP packet version 3. However, a quick trace is showing that the packets are indeed in v2.

Any ideas on why this is happening would be greatly appreciated. Below, also find console output and parts of the trace.

Many thanks in advance.

Cheers
