Hello,
I spotted at least one issue: you set the branch flag (with setbflag())
but then you test message/transaction flags with isflagset() -- to test
branch flags you have to use isbflagset().
Cheers,
Daniel

Hello Daniel,
thanks for the reply. I try out your suggestion, but this is not
working. There is no sound transmitted and the connection ended after
23 seconds (I think a timer is expired).
Scenario is:
Kamailio route all internal calls only internal (external vice versa)
Kamailio route all internal to external through rtpproxy (also vice
versa)
INT_IP: 203.207.111.58
EXT_IP: 193.16.163.58
Here my code:
request_route {
if(is_method("REGISTER")) {
if(dst_ip==203.207.111.58){
setbflag(20);
}else{
setbflag(21);
}
}
}
Route [NATMANAGE]
if(dst_ip==203.207.111.58 && isflagset(20)){
rtpproxy_manage("coii");
}else if(dst_ip==203.207.111.58 && isflagset(21)){
rtpproxy_manage("coie");
}else if(dst_ip==193.16.163.58 && isflagset(20)){
rtpproxy_manage("coei");
}else if(dst_ip==193.16.163.58 && isflagset(21)){
rtpproxy_manage("coee");
}
Alternative try
if(from_uri=~".*(a)203.207.111.58"&& isflagset(20)){
rtpproxy_manage("coii");
}else if(from_uri=~".*(a)203.207.111.58"&& isflagset(21)){
rtpproxy_manage("coie");
}else if(from_uri=~".*(a)193.16.163.58"&& isflagset(20)){
rtpproxy_manage("coei");
}else if(from_uri=~".*(a)193.16.163.58"&& isflagset(21)){
rtpproxy_manage("coee");
}
Another try
if(from_uri=~".*(a)203.207.111.58" && isflagset(20)){
rtpproxy_manage("coii");
}else if(from_uri=~".*(a)203.207.111.58" && isflagset(21)){
rtpproxy_manage("coie");
}else if(from_uri=~".*(a)193.16.163.58" && isflagset(20)){
rtpproxy_manage("coei");
}else if(from_uri=~".*(a)193.16.163.58" && isflagset(21)){
rtpproxy_manage("coee");
}
RTPproxy config
EXTRA_OPTS="-l 203.207.111.58/193.16.163.58 -m 20000 -M 20100 -d
WARN:LOG_LOCAL1"
Some debugging information are in the txt file. TCPdump debugging does
not shows interesting informations…
Has somebody a good idea which could be helpful? Do you need some more
information?
Cheers,
Kai

*Betreff:* Re: [SR-Users] Routing between 2 domains
Hello,
the src_ip is not a local IP, so do not match it with INT_IP or
EXT_IP. The dst_ip is local ip, but the one on which the interface was
received.
You can test the $fs to see what socket is going to be used for
sending out.
Or set some branch flag for each interface when the registration is
processed and check that in branch route
if(is_method("REGISTER")) {
if(dst_ip==INT_IP){
setbflag(20);
}else{
setbflag(21);
}
}
then in route[NATMANGE] have conditions like:
if(src_ip==INT_IP && isflagset(20)) {
# internal to internal
} else if(src_ip==INT_IP && isflagset(21)) {
# internal to external
} else if ...
Cheers,
Daniel

Hello community,
I work with Kamailio 4.2.0 which is placed between two networks
(with two interfaces) and RTPproxy in bridge mode.
The task from Kamailio is to handle the calls from internal
networks to internal networks only on the internal Interface
without bridging. For external networks vice versa. If the call
comes from external to internal, then the RTPproxy should work in
bridge mode and vice versa. I adapt the example with IPv4 and IPv6
routing, but this is not working for internal to external calls
and vice versa
(http://kb.asipto.com/kamailio:kamailio-mixed-ipv4-ipv6). Only
external calls and only internal calls works. I think the cause of
this behavior is the routing which I implemented to the RTPmanage
part in the Kamailio config.
The error message is given by the internal device. (call from
external to internal)
If I make a call from internal to external, the RTP stream is only
in one direction.
Internal Interface IP: 203.207.111.58
External Interface IP: 193.16.163.58
The RTPproxy config is:
CONTROL_SOCK=udp:127.0.0.1:9000
EXTRA_OPTS="-l 203.207.111.58/193.16.163.58 -d WARN:LOG_LOCAL1"
Kamailio.cfg:
#!define INT_IP 10.96.0.0/14
#!define EXT_IP 193.0.0.0/8
# RTPProxy control and singaling updates for NAT traversal
route[NATMANAGE] {
#!ifdef WITH_NAT
if (is_request()) {
if(has_totag()) {
if(check_route_param("nat=yes")) {
setbflag(FLB_NATB);
}
}
}
if (!(isflagset(FLT_NATS) || isbflagset(FLB_NATB)))
return;
# rtpproxy_manage("co");
# Start Test routing
if((src_ip==INT_IP && dst_ip==EXT_IP)){
rtpproxy_manage("cowie");
}
if((src_ip==EXT_IP && dst_ip==INT_IP)){
rtpproxy_manage("cowei");
}
if (is_request()) {
if (!has_totag()) {
if(t_is_branch_route()) {
add_rr_param(";nat=yes");
}
}
}
if (is_reply()) {
if(isbflagset(FLB_NATB)) {
if(is_first_hop())
set_contact_alias();
}
}
#!endif
return;
}
Can someone help me with the right routing? Do you need some more
debugging information?
Cheers,
Kai
