Hello Daniel
I did some more tests and my previous statement is wrong.
Actually it do call set_contact_alias on 200 reply for INVITEs
but somehow it has no change.
I really missing something here.

Hello Daniel
You are right. 200OK messages are also with private IPs.
I think the problem is that
since I call dlg_bridge with Kamailio's own IP
It sends INVITE messages to itself first then it routes INVITE msg to user
location.
Because of this i see two record routes in the INTIVE headers and 200
reply headers.
if (is_reply()) {
if(isbflagset(FLB_NATB)) {
if(is_first_hop())
set_contact_alias();
}
}
But according to this code in NATMANAGE block, it only set contact if it
is first hope.
Since these messages have two record routes, this code block does not
modify contact field
Am I right? or Am I missing something else?
Thanks

Hello,
dlg_bridge is not using the location table at all, because it has to use
the contact from 200ok of INVITE.
Have you used set_contact_alias() for natted 200ok received for INVITE?
Cheers,
Daniel

Hello Daniel
This is the sample output from our location table;
kamailio=# select username,contact,received,user_agent from location
where username='5678*0012';
username | contact | received |
user_agent
-----------+---------------------------------+-----------------------+---------------------
5678*0012 | sip:5678*0012@192.168.1.21:5090 |
sip:DEVICE_PUBLIC_ADDRESS:5090 | Cisco/SPA504G-7.6.1
(1 row)
After calling dlg_bridge Kamailio firing INVITE and rings the device.
After answering on this device Kamailio firing REFER message.
But as you can see from ngrep output below, Kamailio is trying to send
this message to address in the contact field which is a private IP.

Hello,
can you send the ngrep trace for such case? I would like to look at the
headers to understand properly what do you mean.
Cheers,

Hello
I am trying to implement click 2 call functionality on Kamailio
with dlg_bridge.
But It seems that Kamailio routes REFER messages to devices according to
Contact field of location table instead of Received field.
But if the the IP in the Contact field is private REFER messages are
failing so
does the dlg_bridge.
I called dlg_bridge in the config like this:
dlg_bridge("sip:$param1", "sip:$param2",
"sip:IP_ADDRESS_OF_KAMAILIO:5060");
It rings the device in $param1 but after answering on that device
Kamailio fails to send REFER if the Contact field for that device is
Private IP.
So it fails to initiate a call.
How can I force Kamailio to use Received field for REFER messages
instead of Contact field?
Thanks
Huseyin
