No, I don't think you should register the ChannelProxy directly as a packet
sink. This should just be a proxy class. You can register the voe::Channel
directly.

Oh, this doesn't have an impl. Leftover?

I'll give it a try.
There is a OnRtpPacket method below. Which just passes the packet on to
channel()->OnRtpPacket(...).
