[Blink] SIP Problem with private IP addr

It looks like blink is taking the first private ip address from my local interfaces, no matter to which interface the packets will get routed.
The routing is working as on the server a tcpdump show the incoming packets from 10.20.20.6 to 172.18.0.5, but inside the SIP protocol, IP is 192.168.0.12 which is wrong and makes the server trying to answer Register/Subscribe to 192.168.0.12.
