[asterisk-users] Can't read environment variable

[Joost Kuif | Mobillion]

Hi,
 
I can't read a environment variable in a asterisk dialplan. 
When logged in as user root on the system an 'echo $HOSTNAME' gives the
hostame of the machine.
Asterisk (1.4) is started from the same console.
 
I try to read it like this:
exten => s,n,NoOp(host=${ENV(HOSTNAME)})
 
Does anyone know what i am missing?
 
 
 
Ipv een saaie e-mail een leuk videobericht? Ga naar www.KletsKoppies.nl
