[cisco-voip] Num expands

[Nick Matthews]

When you type bad characters into the command line, the error prompt
says you can.  I wasn't able to get ^ to work but I didn't try too
terribly hard.

In the latest IOS (I'm thinking 15(2)T) they greatly increased the
amount of translation rules you can have, so that ban has been lifted
after 10 something years.  There's a limit on num-exp too, but I think
it's in the realm of 512 entries.
