Hi, I'm running the latest version 7.0.4744 of 3CX and experiencing some difficulties configuring a forward rule to dail an external number if the call isn't answered. Using these settings; Rule Type: No Answer Hours: All Hours Call Type: All Calls Action: Forward Call to External Number Destination: is a Dutch 10 digit cell phone numbr After the 'Add Rule' Button the following error occurs: After the Clear Button the rule has been added, but it's not working correctly. Also the Continue Ringing value in General Forwarding Options, although I change the value to 10 sec. that's about 3 rings it will return to 60 again after refreshing the window, or selecting the forward rule. Any idea?
