Checking if ANI is blank / null?

[Gerry O'Rourke]

Simple question I think?

But I don't see a way using the decision editor to check if a variable is blank or null?

I can write a simple java action element to check, but is there a way to do this without using some simple java custom code?

You can use the decision editor and use cargument type call data and call data type ani and use operator does not exist.

Ahh, I thought that would check if the actual variable exists or not and not the value of the variable itself.

Thanks for the tip. I will give it a test and see.

It turns out that with VXML Server, if you set a variable value to NULL

then VXML Server deletes the variable.

So you'll never have a session or call data variable that exists with a

NULL value.
