   In the dial plan, you can simply have a second instruction with
another Dial() command that will only be hit if the first Dial()
command fails.  This is automatic behaviour.

   Or, if you prefer, you can use ChanAvail() to check if the SIP / IAX
trunk is up and that reachability through it has been verified through
'qualify=' (if you have this turned on), and in the event that it is not,
use GotoIf() to route out to the PSTN via analog lines, like you said.
