Ip address issue

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Setup a local sip server(opensips/asterisk) in local network.(e.g 10.10.4.58)
2. Enable 3G connection and got the public ip address at android phone. (e.g. 
42.70.185.89)
3. Enable WIFI connection instead of 3G connection and got the internal ip 
address at android phone.(e.g. 192.168.3.202)
4. Setup identity & network(enable wifi only) options in Imsdroid.
5. Click on "Sign In" button in Imsdroid.

What is the expected output? What do you see instead?
Expect to connect & register to the local sip server but timeout.

What version of the product are you using? On what operating system?
imsdroid: 2.0.504, 2.0.509
android: 4.0.3

Please provide any additional information below.
use Wireshark to capture the packages and find a wire problem in the source 
field,
the ip address of mobile should be the internal ip address(e.g. 192.168.3.202),
but the ip address seems to be provoid by the phone carrier with 3G 
connection(e.g. 42.70.185.89).
when Imsdroid try to connect to the local sip server before timeout, 
type the command "busybox ifconfig" in the terminal and it show the internal ip 
address(192.168.3.202) at interface wlan0,
also tried to connect to the sip server at same time with other sip 
app(Csipsimple) and it's work.

Hi Mamadou, we are facing the same issue on various phones, like LG Optimus 
Dual (2.3.3), Desire HD (with 4.1 mod) and others.
I saw that Android added the 'isUp()' method to NetworkInterface to check an 
interface's validity.
Is there any similar test that can be performed at Linux layer?

Thank you very much

Marco

on all systems (windows, ios, linux...) the best interface and IP address is 
chosen from the native code using routes and metrics at 
http://code.google.com/p/doubango/source/browse/branches/2.0/doubango/tinyNET/sr
c/tnet_utils.c?r=776#599

on Android, this is done on java as some required functions are missing unless 
you directly link to the core code.
I have changed the code as suggested in comment 3:
