It is not uncommon for Lawyers in the US to question the method by which evidence was gathered. They try to create "reasonable doubt" about the charges against their client in order to get a case dismissed.
I was involved in a case a few years ago, regarding computer technology but not VoIP, and this is exactly the approach the Lawyers took.
I have not personally looked at CALEA requirements. I may have to in the future and I was just asking about mediaproxy's ability to accurately associate a recording with a phone number, date/time, location, etc.
So just to be safe I understand this -- are you telling "RTP proxy intergrity problem" means that a smart lawyer can attack RTP proxy as technically imperfect solution (e.g., because traffic is easy to fake) and invalidate legal value of intercepted calls?
Well, if I was the lawyer I would not hesitate to choose this practice and I would be able to generate some technical arguments too :-)

Does this help?

Steve,
I am having a language difficulty -- what do you mean by mediaproxy's _intergrity_?
Thanks!

This may be a little off topic but what are the legal issues you or your company face with CALEA? I'd be surprised if the integrity of the mediaproxy wouldn't become an issue if such a case went to Court. Have you look into this?
Just curious, Steve

I was thinking about having a group called "spy" in the grp table and anyone with this ACL would be sent to a modified mediaproxy that would capture the RTP.
User that don't have the "spy" ACL would be handled normally and if NAT traversal is needed then use an unmodified media proxy.

Why not use a from/to etc detection in .cfg (using database...) to trigger a remote proxy through the requesting agency They then have the capture issue and you have no monitor or delivery issues? Might require conditions of their placement of a proxy? (but is their problem) Regards Chris

Hi All.
I'm located in the US and would like to comply with the Communications Assistance for Law Enforcement Act (CALEA) that Congress passed which basically says that VoIP providers should have the ability to wiretap conversations for the FBI upon request.
I use mediaproxy for NAT traversal. So my question is how can I be CALEA compliant? I assume I should be able to modify mediaproxy to write RTP streams to disk, but I'm unclear on how to "mix" both sides of the conversation.
Can anyone help with a suggestion?
Regards, Paul
