It looks like the number you called timed out or something. I think
this is beyond what we can help you with, you may have to talk to
whoever manages the switch at the other end to figure out what might be
wrong. In Q.850, for SS7 is says that cause code 31 is:
Call failure information
indicating the failure of
a call due to the lapse
of a timeout or a fault
not covered by specific
causes (examples:
expiry of timers Q.764
not covered by specific
causes, release of
interconnected circuit,
etc.)
Maybe that can help when you have to talk to the switch tech.
