Thank you fr your answer, I'll try to find some workaround. Max

Is there any workaround or registry/ini settings to force IVM to answer immediately to a call? The standard option in "Settings/Answer mode/Answer calls after fixed number of rings (2..20)" doesn't accept 1 or 0 and searching in registry I haven't found anything useful. I need to call an external program immediately at the first ring, in order to switch on a relay on a Building Automation system bus (Knx). The delay due to 2 rings waiting is not acceptable. Thank you in advance Max
