The Dialstatus approach will only work if asterisk is fully aware of
the status. In the case where the poster is sending a call to VoipJet,
asterisk may believe all is well, but in fact the problem is behind
VoipJet somewhere. (Eg, the VoipJet equipment might know the exact
status, but its under no obligation to report that back to asterisk.
All depends upon exactly what failed at VoipJet.)
