[SR-Users] answer back from wrong IP / Interface

[Mihaly Zachar]

Hi Gents,

It turned out that it ran with a wrong config and it was bounded to 0.0.0.0.

In this case the source IP is based on the routing decision, I can
reproduce it.

I think Kamailio should be smarter in this case.

Thanks anyway.

Cheers,
Mitya
