Hello,
Thanks for your reply.. am able to make the call reach from 3CX to Kamailio
using the src_ip, thank you, but still not able to redirect the call invite
from Kamailio to 3CX and send the 302 message.
Kamailio
192.168.111.139
Phone A (192.168.111.11)
302
Phone B (192.168.111.10)
Herby what am putting in my routing:
If (is_method("INVITE"))
{ if(!load_gateway("1")) {
sl_send_reply("503", "unable to load gateways");
Exit; }
{ if(! next_gateway()) {
sl_send_reply("503", "unable to find gateways");
Exit; }
Route(1);
$ru = "192.168.111.138";
send_reply("302", "Redirected";
Km_append_branch(“uri”);
Exit;
What am I doing is wrong in the above script? And causing “call failed”!
attached ‘test.txt’ the ngrep capture if needed.
Your help is highly appreciated.
Kind Regards,
F Chahrour

Hello,
if you know the IP address of 3CX, then you can skip authentication for that,
like:
if(src_ip==__3cx_ip__) {
# don't do authentication for the traffic coming here
}
You can use permission module to store the a list of ip addresses and then use
functions from that module to match against source ip of requests, as
alternative to above, providing more flexibility when dealing with lot of
trusted ip addresses.
Cheers,
Daniel

Hello Danial,
Hereby details:
My current working 1st scenario is a call generated from A-party x-lite
registered on kamalio, this call is routed based on kamailio lcr routing module
which add prefix and send prefix to 3CX then 3CX forward the call to B-party
x-lite, registered on 3CX, successfully.
In kamailio.cfg routing logic I only used :
...
If (is_method("INVITE"))
{ if(!load_gateway("1")) {
sl_send_reply("503", "unable to load gateways");
Exit; }
{ if(! next_gateway()) {
sl_send_reply("503", "unable to find gateways");
Exit; }
Route(1);
....
Now, my target is to register also the A-party x-lite to 3CX where I added a
rule in 3CX to forward the call comming to kamailio to take the route desicion
and act.
So, here I need to know how can I tell kamailio to accept the call from 3CX?
this is what I meant by configuring 3CX on kamailio.
I have weakness in the routing logic configuration, could you please help in
this too! What is the required replacement on the above to be done?
Moreover, I appreciate if you provide with docs or tutorials that can help me
understand more kamailio's routing logic functions!
Much appreciated.
Thanks in advance.

Dears,
I have an installed 3CX where I want to generate a call from it to the Kamailo
to get a list of suppliers to terminate the call to.
Thus, the Kamailio should act as a sip redirect to the 3CX (for routing
decision).
Have you tried such configuration before? And how do I configure the 3CX on the
Kamailio?
I don't understand what you expect from 'configure the 3CX on the Kamailio',
can you add more details ?
For sending a redirect, practically you have to update request uri and then
send the 3xx reply, like:
$ru = <sip:[email protected]> "sip:[email protected]";
send_reply("302", "Redirected";
If you need to put more contacts in the redirect reply, then add:
km_append_branch("uri");
uri parameter can contain variables.
Cheers,
Daniel
