Summary:                    App Dial "crashes" when received a 484 (Address
Incomplete) from a SIP Trunk
Description: 
I'm trying to make a call over a SIP Trunk (oferred by one Voip Company).
All works fine, but when I put a invalid (not expected number), the SIP
Trunk come back with a 484 "Address Incomplete" from the SIP Trunk.
And at this time, the DIALPLAN comes out of any extension and priority,
junst reporting:

   -- Got SIP response 484 "Address Incomplete" back from X.X.X.X
  == Everyone is busy/congested at this time (1:0/0/1)
  == Spawn extension (macro-dial-external, s, 5) exited non-zero on
'SIP/10000-00000000' in macro 'dial-external'
  == Spawn extension (Rota_Inicial, 02125405285, 3) exited INCOMPLETE on
'SIP/10000-00000000'
[2010-06-02 14:59:28.784] WARNING[4068]: pbx.c:4358 __ast_pbx_run: Channel
'SIP/10000-00000000' sent into invalid extension '02125405285' in context
'Rota_Inicial', but no invalid handler

I tried the same in a very simple DIALPLAN, something like (JUST AN
EXAMPLE):
exten => _X., 1, Noop(Hello)
exten => _X., 2, Answer
exten => _X., 3, Dial(SIP/mysiptrunk/${EXTEN},300)
exten => _X., 4, Noop(${DIALSTATUS})

The result is allways the same: when calling a valid (expected) number,
works fine including the "4" priority (in this example). When calling a non
expected number for the sip trunk, never comes to the 4 priority, ending
before, receiving the messages above.

Below comes all the real configuration of the situation exaplaned. But is
just for illustration, because it occurs too in a simple way, like the
example above.
