hi, all
is it possible to implement with an openser a legal interception? maybe with t_replicate() to another server.
what about the media forking of the call?
thanks

using latest cvs head, check the siptrace module:

what about the media forking of the call?
latest rtpproxy should have some features in this respect.

thanks

unfortunaly our SBC for lawful intercept don't discriminate single call but only all traffic.
I imaging something like that:
RTP UA ----------------------------------------------- UA | \ / | | \ / | | + ---> SBC ----> OpenSER(1) ---> PSTN --- + | | | | \ | UA call replicated | \ | | \ OpenSER(2) | \ | / \ | / \ RTP | RTP / +--------------- LawUA ------------------+
- SBC do the NAT traversal - OpenSER(1) dont'n know about media, only signaling - OpenSER(2) i think nathelper and rtproxy goes here
hmmm
sorry i'm dreaming ;)

I do not know how you could force the UA to fork the media. Also, legal interception has to be transparent for the UA, otherwise they can detect that something happen with the call and tear down.
