Group_Count Problems


I am having Problems using Group_Count function. Means, as soon as I use that function and transfer it the call to an another extension, the count doesnt decrease from 1 to 0.

Is there any way to decrease the group_count as soon as the call is getting transfered ?

I am using:
exten => 1,1,Set(GROUP()=dect)


Did you every get this resolved?
