[SR-Users] set_advertised_address

[Kjeld Flarup]

So I could do something like this:

listen=192.168.2.9:5070 advertise 20.30.40.50:5070
listen=192.168.2.9:5050

However when I do an invite to 192.168.2.32, would Kamailio choose 5050 
or 5070?
Same when inviting to 40.40.40.40

If I were to listen to another local IP, then the routing table in Linux 
could perhaps dictate which connection to use.
