[SR-Users] RTPproxy on Kamailio 3.2.1 difficulty.

[nunu abe]

Dear Daniel,
Greetings and Happy New year to you all! I would like to thank you very much for your detailed and well structured tutorials on Kamailio. I am resending this email as I sent the earlier one before I was a member of the mailing list and I thought it may have been sent to the spam folder. If not then, I apologize for double posting.
I was trying to design a similar scenario like the one " Run your own SIP VoIP service on both IPv4 and IPv6 " as explained on Asipto web-page(http://kb.asipto.com/kamailio:kamailio-mixed-ipv4-ipv6). However I ran into difficulties with rtpproxy. The proxy is not routing media packets as it should. I followed the instruction regarding the kamailio.cfg file and edited the necessary lines according to my settings. I think my problem comes from setting up the rtpproxy.
1. I edited the /etc/default/rtpproxy file. i.e. I uncommented the line -  CONTROL_SOCK="unix:/var/run/rtpproxy/rtpproxy.sock"
2. I started the rtpproxy with this command: rtpproxy -F -l ADDR_IPV4 -6 /ADDR_IPV6 . However, after this command the system returns the message : rtpproxy: setbindhost: No address associated with hostname
It displays the same message even when I replace ADDR_IPV4 and ADDR_IPV6 with IP addresses.
 
3. I have also tried using the udp socket:- CONTROL_SOCK=udp:127.0.0.1:22222, of course I have replaced the unix socket by this udp socket in the kamilio.cfg file. 
So my question is, what did I do wrong with the settings that SIP messages are traversing normal from IPv4 client to IPv6 client and vice versa but media files(RTP packets) are not? The rtpproxy receives the media files from one client but fails to forward them to the other client. 
Thanks for your help.
