Hey... look at that ... it works! Cool :)

So... asterisk can't tell the difference between 's' for 'no extension
dialled', and when 's' was actually the name of the extension dialled...
is this the expected behaviour?

More importantly, is this a security risk in any way? I can't think of a
situation where it would be...

Even more importantly, could this change in a future version?

Thanks
