Automon [featuremap]

Hi all,

I’m trying to use the automon feature and it’s not working… I was wondering if it’s suppose to be working on Asterisk 1.0.9 ?

If yes what should be done to make it work ?

I have in features.conf
automon => *1

And my dial string in extension.conf is like that :
exten => s,1,Dial(SIP/${ARG1},20,TW)

Thanks !
