I know that I should know this. But I'm having serious brain farts at the moment. I want to have a call be counted in a number of ways outbound inbound potential so, for example, a call comes into my dialplan, I want to add it to TotalCalls (all calls inbound + outbound) InboundCalls (all inbound calls) Potenial (all inbound calls that may potentially enter a conference) Potenial (all inbound calls that may potentially enter a conference by conference name) the potential category needs to be decremented when the call actually enters a conference so, I have exten => _[0-9A-Za-z].,n,Set(GROUP(conference)=TotalCalls) exten => _[0-9A-Za-z].,n,Set(GROUP(conference)=Inbound) exten => _[0-9A-Za-z].,n,Set(GROUP(conference)= Potenial) exten => _[0-9A-Za-z].,n,Set(GROUP()= Potenial_${CONFNAME}) group_count(inbound) group_count(inbound at conference) group_count(potential at conference) group_count(potential_${CONFNAME} ) however, when the call enters the conference, I need to unset the potential calls groups how do I do this ? /me feels very very stupid Julian -- Julian Lyndon-Smith IT Director, Dot R Limited "I don?t care if it works on your machine!
