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 ;)
