<br>
Is there any way to check if a variable is set in asterisk? I've had a<br>
look around and can't find a purpose built function for it.<br>
<br>
I'm going to be using it to see if an argument has been passed with a<br>
macro or not (e.g. see if ${ARG3} is set or not)<br>
<br>
Thanks in advance<br>
<br>
Ish<br>
