Because not every country allows telecom operators to record to WAV
files on a generic machine and email/ftp/whatever every single file once
a day to the authorities. Usually they want "realtime" access and in
those cases you want to fork the media (and the signalling probably, I
don't know for sure).
Exactly. There are countries requiring for example "PacketCable Event
Messages" compliant messages sent to LEA. Beside that, also
corresponding media has to be handed over. Just as an example.
This is a fact we unfortunately have to live with, no matter if OpenSER,
Kamailio, or Nortel CS2k or whatever is deployed...
