Interesting. I heard of CALEA in the past and wondered how CALEA is implemented.
>The IP-based "soft switches" typically do not contain a built-in CALEA intercept feature
Is there a specification you must follow? Like maybe you had a VOIP company with your own custom protocol or softphone, would you just code up some web interface where they have a login and then type in a number to see if any active calls, then click a "Listen" button then an audio stream starts playing. Or is there a well defined way for them to access the call, audio codec, etc has to be?
