Re: [Serusers] RTP Wiretapping

Jiri: 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.
