[Freeswitch-users] LUA and return variables

Hi guys (and girls)!

I'm working on a little bit of ENUM trickery and I tried doing some  
(illegal) nested conditions. :-)

What I want to do is to first check enum with the ENUM application,  
then depending on the answer do some stuff. Say that the domain part  
of the ENUM answer is robin.nl, then I want to do action X instead of  
just briding the enum answer directly as I see in most examples.

But I remembered that it wasn't allowed to do nested conditions. So  
what I did was stacked conditions. After that I read the dialplan wiki  
pages again and figured that my regexp never matches because variables  
I "set" during some phase of the extension I can't use in the same  
"go" as another condition. So, now my plan is to use LUA to do the  

I'll pass the enum answer to a lua script which will split the answer  
in a user and domain part and return those two to the main app. Then  
based on those two vars I'll do routing or other actions (like, prefix  
and then route).

Is this how I'm supposed to do it? I can't find many examples on  
manipulating ENUM answers, other than bridging them directly. I can't  
change the way I do stuff to ENUM answers, because in most cases I'll  
just route them out the standard way.

Anyone with experience on fiddling with ENUM answers?
