I think he is speaking about LAW requirements about call-recording/call-interception
And why is forking required for that? if the audio goes through a rtpproxy, why is it required to fork it? why doesn't the recording take place in the same host?
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...
