[Asterisk-Users] NOTICE[507921]: app_dial.c:742 dial_exec: Unable to create channel of type 'Zap'

[Rich Adamson]

Looks like asterisk is trying to send the call out Zap/1, but is having
an issue that appears almost like there is no telephone line attached to
your x100p card. Is this machine located in the US and are you sure
the pstn line is properly plugged to the card?
Another remote possibility is that asterisk is detecting a busy signal
on the pstn line. If you are in the US, what is 403142142? That isn't
a standard US telephone number. (Nine digits?) Again, if this is in the
US, best guess is that sending those digits out the pstn line is 
resulting in some sort of busy/congestion tone coming back from your
telco.
