Hi Vikram

Yes, SIP messages are being proxied, otherwise the call wouldn't be possible.

Here are the SIP messages that are being proxied in case this helps to debug my problem

interface: eth1 (192.168.34.1/255.255.255.240)
filter: (ip or ip6) and ( port 5060 )

I'm no expert when it comes to rtpproxy or Kamailio , but i've
encountered a similar problem in the past. I took a quick look at your
logfile and i noticed that there aren't any SIP messages in the log (eg.
REGISTER, INVITE...). Are you sure that SIP messages are being proxied ?
if not recording would not be possible.

Regards,
Vikram.
