For "briding" you have to isntruct rtpproxy when to use which interface.<br>
<br>
Thus, in kamailio.cfg, when processing a message, find out if the message goes from v4 to v6, or vice versa , or v4-v4 or v6-v6.<br>
<br>
Then instruct rtpproxy about the direction using the 'e' and 'i' flag. i stands for internal and means rtpproxy's first interface, e for external and rtpproxy's second interface.<br>
<br>
<a href="http://kamailio.org/docs/modules/3.2.x/modules/rtpproxy.html#id2535618" target="_blank">http://kamailio.org/docs/<u></u>modules/3.2.x/modules/<u></u>rtpproxy.html#id2535618</a><br>
<br>
Thus, when starting rtpproxy with "-l 192.168.6.2 -6 /2001:6666:6666:6666::2" the internal interface is v4, the external is v6.<br>
<br>
Thus, for example when processing an INVITE sent from v4 to v6, use the rtpproxy flags 'ie', for the 200 OK use 'ei'.<br>

Hi,<br>
<br>
I am trying to use RTPproxy 1.2.1 in bridge mode between IPv4 and IPv6<br>
together with Kamailio 3.2. I configured and ran it on server together<br>
with Kamailio.<br>
I start it with parameters:<br>
-l 192.168.6.2 -6 /2001:6666:6666:6666::2 -s udp:localhost:7722<br>
SIP messages are correctly exchanged, SDP looks to be translated, but<br>
when RTP session starts, I see RTP flow only from UC1 to RTPproxy and<br>
nothing more.<br>
On RTPproxy server I see 4 open ports for IPv4 address but no one for<br>
IPv6 address.<br>
When I tried to change start parameters to<br></div>
-6 2001:6666:6666:6666::2 -l /<a href="http://192.168.6.2" target="_blank">192.168.6.2</a> <<a href="http://192.168.6.2/" target="_blank">http://192.168.6.2/</a>> -s<div class="im"><br>
udp:localhost:7722<br>
I could see 4 open ports for IPv6 address but no one for IPv4 address.<br>
<br>
Can anybody help? do you know about any known error? can it be related<br>
to Kamailio or RTPproxy?<br>
<br>
thank you,<br>
Lukas Lani<br>
