"intercept" calls during voicemail


I’m installing an asterisk in my home environment, and it work like a dream !

There is one functionality I miss from my simple answering machine… If I’m too far from my phone and the voicemail take the call, I would like to be able to put it back to the phone…

I tried the “steal” function from the “bristuff” patch, but I could’nt have it working…

Is there another way to “steal” an answered channel ?
