Hi Klaus,
I reviewed once again mine kamailio.cfg. I use code from
http://kb.asipto.com/kamailio:kamailio-mixed-ipv4-ipv6
where rtpproxy_manage("FAIE") or rtpproxy_manage("FAEI") functions are
to relay
RTP.
/////
# RTPProxy control
route[NATMANAGE] {#!ifdef WITH_NAT
if (is_request()) {
if(has_totag()) {
if(check_route_param("nat=yes")) {
setbflag(FLB_NATB);
} else {
if(check_route_param("nat=v46")) {
setbflag(FLB_V4V6);
}
}
}
}
if (!(isflagset(FLT_NATS) || isbflagset(FLB_NATB)
|| isbflagset(FLB_V4V6)))
return;
if(isbflagset(FLB_V4V6)) {
if(af==INET6) {
rtpproxy_manage("FAEI");
} else {
rtpproxy_manage("FAIE");
}
} else {
if(af==INET6) {
rtpproxy_manage("FAEE");
} else {
rtpproxy_manage("FAII");
}
}
if (is_request()) {
if (!has_totag()) {
if(isbflagset(FLB_V4V6)) {
add_rr_param(";nat=v46");
} else {
add_rr_param(";nat=yes");
}
}
}
if (is_reply()) {
if(isbflagset(FLB_NATB)) {
if(af==INET) {
fix_nated_contact();
}
}
}#!endif
return;}
/////
...but either it looks like does not work for me.

For "briding" you have to isntruct rtpproxy
when to use which interface.
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.
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.
http://kamailio.org/docs/**modules/3.2.x/modules/**rtpproxy.html#id2535618&…
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.
Thus, for example when processing an INVITE sent from v4 to v6, use the
rtpproxy flags 'ie', for the 200 OK use 'ei'.

Klaus

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