[Freeswitch-users] Variable manipulation in the dialplan

[Saeed Ahmed]

Can we also test dialplan using CLI, like "dial" in asterisk?

Thanks anthm!
This way to test directly on the cli is really nice, I didn't know of
it.
If I've understood well, a negative number as first parameter will make
the second parameter useless/meaningless.
Besides, the second parameter is useless/meaningless if set equal to 0
or lesser than 0.

I still think that we could benefit from more power here in the
dialplan,
if I have 
12346578 at domain.org
I'm not able to grab out the number (of which I don't know the length)
even if I know that domain.org is always the same length.
I've looked for something useful in
http://apr.apache.org/docs/apr/1.3/apr__strings_8h.html
and switch_apr.c
but I think I'll end up calling an external script. :)

Best Regars,
Claudio
