[Serusers] A gateway problem

[Steve Blair]

   Log into your gateway, get into enable mode and type
show dialplan number  <put your called number here>. The command will tell
you the number and sequence of the dial peers that are matched for
this nunber. It will also show what number expansion, if any, has been
done. From this you should be able to tell if your dial peers are forwarding
traffic correctly.
