[asterisk-users] How to access environment variable?

[Larry Alkoff]

I was only trying to demonstrate that my special variable MYIP was 
indeed in the environment of the shell.  I suspect it's not in the 
Asterisk process environment - why I dunno.

I'll look at that tomorrow but suspect I'll never be able to read the 
MYIP variable from Asterisk.
