[cisco-voip] Destination Pattern Question

[Jason Burton]

You are correct the ^ character matches every but whats contained.
 
Looking in the 4.1(3) system guide you will find the following
 
The circumflex (^) character, used with the square brackets, negates a range of values. Ensure that it is the first character following the opening bracket ([). 

Each route pattern can have only one ^ character. 

 The route pattern 813510[^0-5] routes or blocks all numbers in the range 8135106 through 8135109.

The first two regular expression characters I learned were ^ and $ (beginning and ending of a string)... (BGP).

To be honest, I can't see how someone could say that the ^ means NOT...

However, I just found this: 

[^ ] Matches a single character that is not contained within the brackets. For example, [^abc] matches any character other than "a", "b", or "c". [^a-z] matches any single character that is not a lowercase letter. 

So, we are wrong, they are right... we suck.

	The ^ matches the beginning of a string.
	
	The [ ] match a range.
	
	So, my thinking would be that the [^9] should match anything that begins with a 9
	
	However, so would:
	
	9...
	
	To match the not-9 do this: 
	
	[1-8]...

		Can someone confirm what this statement does?    It was added with the idea that everthing will match except anything beginning with 9.  From what I read it looks like it will match all ext's beginning with 9.
