Summary:                    [patch] [SIP realtime] "sip reload" makes
UNREACHABLE users behind NAT
Description: 
When a SIP dynamic realtime user is registered behind NAT (with "nat=yes"),
a "sip reload" command makes Asterisk "forgetting" the public location of
the peer, and instead uses the private address of Contact header to reach
it. Of course it fails and causes the user to be UNREACHABLE.

I have tryed versions 1.4.24 and 1.4.25 with and without the patch.

I haven been able to reproduce the bug when rtupdate was unset. When set,
the bug appeared 100% of the times.

After aplying the patch the bug did not appear in any case. It worked for
me.
