[OpenSIPS-Users] Passive call recording using rtpproxy

[Bogdan-Andrei Iancu]

Hi Alexis,

To record the RTP on the your platform, you need first to get the RTP to 
flow through your servers, right ? So you have to do RTP pinning - to be 
transparent for the users (if recorded or not), you will have to do it 
for all calls I guess. And here you can use RTPproxy to pin the media.

Now, once you have the RTP on your servers (via rtpproxy), you have 2 
options:
     1) get the recording directly from RTPProxy
     2) get the RTP via port mirroring

Let me know if ok so far.

Best regards,
