Unless this is only a paraphrase of what you have, I think you should
use ${EXTEN} instead of ${ARG1}:

[from-pstn]
exten => _555573XX,1,Dial(DAHDI/g1/${EXTEN},,T)

And here, why the 's' extension? I would do:

[from-nec]
exten => _X!,,1,Dial(DAHDI/g1/${EXTEN},,T)

I think ${ARG1} etc should only be used within macros.
