[SIPForum-techwg] RTCP What?

[Cullen Jennings]

You right Roni - I was confused.

I'd propose the spec say that SP that want to monitor media quality  
need to deploy and Acme^H^H^H^H media relay box. This of course begs  
the question of what do they plan to do about anonymous calls from one  
SMB to another SMB. Are they going to hide the IP of the SMB? If they  
are, the only practical to deploy way I am aware of is a media relay.
