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?
Regards,
F Charour

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:newnumber@newdomain.com"; 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.

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.

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.

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.

Hi Daniel,
The call is not redirected to 1st kamailio, below is the call trace where 2nd kamailio(192.168.111.139) send request to 192.168.111.15 which is the gateway in the lcr rule instead of sending this invite to 192.168.111.138.

My problem is hereà This is my Kamailio routing configured on 2nd kamailio which I want from it to send back the call, with lcr_gateway already defined, to 1st Kamailio:

send_reply("302","rEdIrEcTeD");
km_append_branch("uri");
}
Am looking through many documents but can’t achieve my target, I want the 2nd Kamailio, which has LCR configured on it, to send back to 1st Kamailio the gateway from lcr_gateways with 302 redirect message.
My questions are:
How to achieve this?
Do you suggest any document that help?
Do I need to load any specific module?

Dear Daniel,
Attached is my config file.
Is it correct to set $ru=”sip:.*@192.168.111.138"; in case I need any number to be redirected to 192.168.111.138.
Thanks.

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.

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:newnumber@newdomain.com "sip:newnumber@newdomain.com"; 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
Hi again,
I really need your help in my testing lab here!!
I have simplified the scenario and changed configs to make it easy pinpoint the redirect issue and then apply on my real scenario:
Two Phones(username: 106 and 107) registered on Kamailio1 (192.168.111.138).
- Phone 106: dial 107 àOK
- Kamailio routing forward call to Kamailio2(192.168.111.139) àOK
- Then Kamailio should only receive the call from Kamailio1 and redirect it back to Kamailio1 àNOT OK
Note: In my real scenario Kamailio 2 will be responsible for taking the routing decision based on its defined LCR rules and redirect the call with rewritten uri to Kamailio1.
Setting in Kamailio2 routing script the following is not working till now:
$ru = "sip:107@192.168.111.138"; send_reply("302", "Redirected"); Km_append_branch(“uri”);
Kamailio2 is not sending the 302 message and this is my problem.
How can I send the 302 message redirect? And where do I have to place or put the related function in the script?
Thank you.

Hello,
It works now.. It was not an issue in the function you provided but in the presence of route(1) before $ru = "sip:" + $rU + "@192.168.111.138"; in the script.
And successfully kamailio2 now is able to send the 302 message to .138.
Now I’ll work on letting Kamailio1 handle the 302 message in order to make successful call.
Thank you Daniel very much for your help.

This is my Kamailio routing logic configured on the 1st Kamailio to forward any call from 1^st kamialio to 2^nd kamailio:
if (is_method("INVITE"))
{
Sethostport(“192.168.111.139:5060”);
Append_branch();
}
My problem is hereàThis is my Kamailio routing configured on 2^nd kamailio which I want from it to send back the call, with lcr_gateway already defined, to 1^st Kamailio:
if (is_method("INVITE"))
{
if (!load_gws("1")) {
sl_send_reply("503", "Unable to load gateways");
exit;
}
if(!next_gw()){
sl_send_reply("503", "Unable to find a gateway");
exit;}
route(1);
$ru="sip:.*@192.168.111.138";
send_reply("302","rEdIrEcTeD");
km_append_branch("uri");
}
Am looking through many documents but can’t achieve my target, I want the 2^nd Kamailio, which has LCR configured on it, to send back to 1^st Kamailio the gateway from lcr_gateways with 302 redirect message.
My questions are:
How to achieve this?
Do you suggest any document that help?
Do I need to load any specific module?
Thanks,
F Chahrour

Hello, You set r-uri ($ru) to an IP address only -- it has to be a full SIP URI.

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.

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:newnumber@newdomain.com" <sip:newnumber@newdomain.com>; 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.
