Yes, I know, way behind. We are trying to make the time needed to move on to 11 or 12, but it is quite time consuming. Although we're not alone, at least Steve Edwards uses 1.2.. :)

I tested SIPFROMDOMAIN, and it worked. Important thing to note is that I needed to have at least one underscore at the beginning of the variable, as your example did, it needs to be inherited at least one level. I don't really see way this should be needed, shouldn't Dial be able see it in the channel that executes the application? Maybe this should be noted on the wiki as well, to avoid this kind of confusion? 

Thanks for the help!
