Hi, Negating is done with [^...] in a regex, so 'not 1' is matched with: /^[^1]$/ If you want to match on a longer sequence, you can do that with negative lookahead, for example 'not 123' can be matched like this: /^(?!123$)\d{3}$/ regards, Leon On Oct 21, 2009, at 1:34 PM, Mark Campbell-Smith wrote:
Hi!
How do I do a NOT equal to in a dialplan expression
Normaly in regex I would use the ! character. This doesn't seem to work in FS..
ie <condition field="${variable}" expression="!^1">
Shouldn't that match when the variable is not starting with one?
