Yep.. using the SPAN port now. I imagine there will be ways to get around
this nuisance, by encrypting the traffic, or something..

AFAIK, these records (Nice, Witness) only work on a LAN (through passive
sniffing on a hub or using a span port) or through a conference server. 
Either way, it'll require the RTP to be proxied through the provider. In
reality, the problem might not be as bad, many SIP-based providers are
already using ALGs (Application Layer Gateway) to help NAT traversal. 
These ALGs will proxied RTP if the phone is behind NAT. In theory, it should
be possible to record the streams from the ALG.
