asterisk users - Sep 2019 - asterisk-users Digest, Vol 181, Issue 3

Thank you a lot for your kindly help and reply. Actually it helped me a lot.I
was using _X. in the extensions.conf at the trunkinbound context.Can you advise
me what is the difference between _X. and s? In other words, when it is better
to use s and when it is better to use _X.?
Again, I am fully thanks for you.RegardsBilal

OPTIONS is treated as if it were an INVITE, so it looks up the extension in the
dialplan. The following shows what extension and context:

[Sep 4 12:42:20] Looking for s in trunkinbound (domain 10.240.147.26)

If you add an "s" extension to the "trunkinbound" context it
should then respond 200 OK.

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.

Cheers
Tony
