Hi again,
My kamailio 1.5 is working well and I'm able to create the session between an IPv4 and an IPv6 UA, but there is no RTP session. That's the point where the rtpproxy comes in. I installed it, and made a bridging (I hope it is): /usr/local/bin/rtpproxy -F -l /192.168.124.146 -6 FEC0:0:0:0:0:0:0:2 and started rtpproxy -F start. But there is no RTP traffic yet.
I read here ( https://www1.ethz.ch/id/people/allid_list/armin/SIP-IPv4-IPv6.pdf ) I have to make two tables named â01Clocation _inet4â01D and â01Clocation_inet6â01D instead of the only â01Clocationâ01D. If it's true, were can I add these? Because it says: "If mySQL is used, the mySQL initialization script (/usr/local/sbin/ser_mysql.sh) has to be modified to create two additional tables" But there is no /usr/local/sbin/ser_mysql.sh on my computer. Where else can I add these tables?
Thanks, Peter

Hi again,
My kamailio 1.5 is working well and I'm able to create the session between an IPv4 and an IPv6 UA, but there is no RTP session. That's the point where the rtpproxy comes in. I installed it, and made a bridging (I hope it is): /usr/local/bin/rtpproxy -F -l /192.168.124.146 -6 FEC0:0:0:0:0:0:0:2 and started rtpproxy -F start. But there is no RTP traffic yet.
I start rtpproxy using the startup script. Therefore I modified the startup script /etc/init.d/rtpproxy (IIRC it is provided with the rtpproxy source code but must be installed manually):
EXTRA_OPTS="-m 10000 -M 12000 -l 11.136.32.162 -6 /2a02:850:1:1:216:3eff:feef:1ffe"
in this case 11.136.32.162 is the 'i'nternal interface and 2a02:FFFF:1:1:216:3eff:feef:1ffe is the 'e'xternal interface.
In kamailio.cfg you have to make sure that you call force_rtp_proxy() with proper flags to instruct rtpproxy if you need RTP proxying between v4-v4, v6-v6, v4-v6 or v6-v4.
The i and e flags is what you need, take a look at the documentation of http://www.kamailio.org/docs/modules/3.1.x/modules_k/rtpproxy.html#id2581697
(this is for 3.1, but the flags are the same for 1.5, and the 1.5 doc is not that clear).
Thus, in kamailio.cfg, you have to find out the flow of the INVITE, and if for example the flow is from an v4 client to an v6 client, then you have to call (when as above the v4 it the internal interface and the v6 is the external interface): force_rtp_proxy("ie")
For the respective 200 OK response you have to call force_rtp_proxy("ei").
If a call is v4->v4 then you call for requests and responses force_rtp_proxy("ii"). If a call is v6->v6 then you have to call for requests and responses force_rtp_proxy("ee")

You can have v4 and v6 clients and the same location table - no problem. But the thing is that it is difficult to find out if the target will be v4 or v6. By separating the v4 and v6 users into separate location tables then you can lookup one or the other and find out if the registered client was registered by ipv4 or ipv6.
