How's that?  Of course Vonage can intercept RTP streams.  Either it cross
their SIP proxy servers, SBCs, or TDM gateways to the PSTN.

As I mentioned in the previous email, if the VoIP crosses our data network
and we have a data tap order, then yes, we will of course be capturing those
RTP and SIP packets, but it's not our job to play back the audio.  We will
just send the data back to the LEA.

What do you mean that Vonage has washed their hands of this?  There are
multiple sources pointing to Vonage becoming CALEA compliant:

If the LEA wants to tap a Vonage line they're going to start with IP
telephony provider which is Vonage, not the broadband provider.   Why would
they start with a broadband provider for a voice call?  I can see some
mitigating circumstances, such as if the internet link was poor that the LEA
might want to go closer to the edge of to obtain a better quality RTP
stream, but that's pure speculation on my part.

It depends if you're talking about PacketCable or their routers.  See
