This is what I use.  You can see all variables related to the channel by 
using DumpChan app.  From the CLI, you can also do a show channel 
<blah>.  I remember there were some got-yas when using macros.  Take a 
look using DumpChan everywhere to make sure what variables are set 
first.  Doing a show channel from the CLI will show you all variables on 
the channel after the answer, which can vary from what is available in 
your macro at the time.
