Hello. For school i am doing a project with VoIP. Doing this i came to 3cx, because its very easy to use and manage. After working with it for a bit, i got everything working in my local network. I could call with everyone in the network and it seemed to work fine. After that i wanted to make it possible for people to call from outside of the network to the inside. This is were my problem popped up. When i was trying to connect with my phone from the outside it said it in the server logs ''WAN IP Blocked''. This was easily solved by going to the extensions properties and removing ''Disallow use of extension outside the LAN''. After that i tried reconnecting with my phone, but now i had a different error. It said on the phone ''Out of office request timed out''. At this point there was also nothing in the server logs about the connecting, when before it said ''WAN IP blocked''. I'm using the 3cx App on my iPad/iPhone to create the connection. The firewall checker tells me all the ports are open and that everything should be fine. I've also portforwarded everything in my router correctly. Saying this i guessed it should totally work. Also on the internet i can't find anything for this problem except for the problem i had before. Does anybody have any clue how to solve this, because i can't find it. Any help on this would be amazing.
