[asterisk-users] Dial plan Question

[Doug Crompton]

I am trying to do something that I see describe in a book and it is not
working....

In my sip.conf, I have in my [fxo] context=from-pstn

I then have in extensions.conf

[from-pstn]

exten s,1,answer()
exten s,2,playback(blah)

etc.

It never answers.... but if I do this

[from-pstn]

exten _x.,1,answer()
exten _x.,2,playback(blah)

it works.  Why does the 's' extension not work here?
