[reSIProcate] How can I catch the interface that received a SipMessage

[Lorenzo <webmaster@xxxxxxxxxxxxx>]

Hi all,
I have got a machine with more than one IP Address (interface) and I 
want to know the IP Address of the interface that catch the SipMessage.
How can I do?
The getDestination() return 0.0.0.0 instead the getSource() return the 
real source address.

Any tips appreaced!
