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 at 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.
