They do different things.

_X. will match any extension number beginning with a digit. This is what
you would normally use to match incoming calls that specify a number,
and is presumably what you have already.

s will only match is no extension number is given. This would be the case
for an analogue line, for example, or a SIP connection that didn't give
a destination number. It is also matched for OPTIONS requests used to
handle "qualify".

So in your [trunkinbound] context, just add a line like this:

exten => s,1,Hangup

And leave everything else in that context unchanged.
