> 14:40 <ra21vi> newtonr: :) I am using GetVar in AGI, and it returns val already set
> 14:40 <ra21vi> in AMI do getvar process any expression before returning the result?
> 14:43 <newtonr> ra21vi: yeah it should
> 14:47 <newtonr> ra21vi: but not sure about AGI, I don't use it much
> 14:47 <coreyf1513> ra21vi: no, in AMI getvar does not accept an expression as input, it accepts a variable name or a function call, so SHA1(junk) works for getvar, not ${SHA1(junk)}
> 14:48 -!- nickfennell [~nickfenne at unaffiliated/nickfennell] has joined #asterisk
> 14:49 <coreyf1513> oops, looks like it does process expressions but it expects the result of those expressions to be a variable name or function call
