+Q: I have two Internet connections, one is my main connection and the

+A: Siproxd itself does not include support for such a thing. However what
+   you can do is, use 2 different siproxd configuration files (with the
+   two different outbound interfaces configured). Then, if the main
+   interface goes down and you activate the backup connection, just
+   copy the second siproxd config file in place and restart siproxd.
+   Active registrations are not lost, as siproxd does save them at exit.
