asterisk users - Aug 2009 - Accessing Asterisk gosub arguments in extensions.lua

How does one go about accessing gosub arguments from Asterisk in 
extensions.lua?

For example, I have the following in extensions.conf:

exten => 1000,1,Wait(1)
exten => 1000,n,Gosub(functions,mytest,1("123"))
exten => 1000,n,Hangup

And then the following in extensions.lua:

extensions = {
   functions = {
     ["mytest"] = function()
       app.saydigits("ARG1")
       app["return"]()
     end;
   };
}

I would like the call to speak "one two three", but instead nothing 
happens because ARG1 isn't available to lua.


Thanks much.

You cannot.  The various methods of dialplan creation are not designed to be
interoperable.  Some people have made various methods work (such as between
extensions.conf and extensions.ael) but those methods are not guaranteed to
work, nor are they supported.

Use one method and stick with it.

Why does Asterisk even have functions in pbx_lua like app.return and 
app.gosub, which jump between extensions.conf and extensions.lua if its 
not supported or guaranteed to work.  Theres nothing in extensions.lua 
or pbx_lua.c, which so far as I can tell are the only available sources 
of documentation for pbx_lua, that suggests extensions.conf 
interoperability doesn't work.

Deciding to switch between a 10,000+ line dialplan in an assembly-like 
language (extensions.conf) over to one in Lua in one all at once is not 
a good position to be in.
