Thank you Sammy for noticing :)

Now I have a bit of different but same problem. After the earlier posting the message I decided to start everything from scratch and I installed everything new. 
But I still have problem. The rtpproxy server is not working, it fails to replace the IP address of the sender in the SDP and hence there is no RTP communication.
These are the steps I followed:


1. Freshly installed kamailio 3.2.1 on Kubuntu from GIT

2. Installed mysql server

4. installed rtpproxy, changed its user to be kamailio.

3.Copied the provided kamailio.cfg file from the link and edited the IP addresses and the DBURL to reflect my settings

4. Uncommented the Control socket line and added these lines in the /etc/default/rtpproxy file
  CONTROL_SOCK="unix:/var/run/rtpproxy/rtpproxy.sock"
  ADDR_IPV4=[10.10.10.10]
  ADDR_IPV6=[3001:0:0:1::10]
  EXTRA_OPTS="-l {ADDR_IPV4} -6 /{ADDR_IPV6}"

*** I aslso tried without adding the last three lines, but it made no difference.***

5. Started rtpproxy in a bridge mode

xxxx at DualStackCS:~$ sudo rtpproxy -F -l 10.10.10.10 -6 /3001:0:0:1::10 
*** I have also tried to start it this way :xxxx at DualStackCS:~$ sudo rtpproxy -F -l 10.10.10.10 -6 /3001:0:0:1::10 -s unix:/var/run/rtpproxy/rtpproxy.sock  - but no difference****

xxxx at DualStackCS:~$ ps aux|grep rtpproxy
root      1522  0.0  0.0  11384   696 ?        Ssl  15:31   0:00 rtpproxy -F -l 10.10.10.10 -6  3001:0:0:1::10
xxxx    1528  0.0  0.0   3324   804 pts/1    S+   15:31   0:00 grep --color=auto rtpproxy

xxxxx at DualStackCS:~$ sudo /etc/init.d/kamailio start


6. Started kamailio
@DualStackCS:~$ sudo /etc/init.d/kamailio restart

I have attached the log file.

Many thanks for your help.

Regards,

Maedot

Hi,

I had a good laugh when I read the reply, but going through the whole thread again I found this:
" It displays the same message even when I replace ADDR_IPV4 and ADDR_IPV6 with IP addresses. "

So there _IS_ some problem here.

Nuno, can you please copy paste the exact command which you executing, plus paste the logs,

Sammy.

>>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.
