Hi currently i am at home testing 3cx with unsupported Fritzbox. So i even found an guide how to setup, but Firewall test is still showing: testing port 5062... full cone test failed On Router 5062 is correctly forwarded according to settings. On Port 5060 i am using Asterisk on a different server without issues. Is this still normal behaviour? Just want to make sure there are no problems with different router, its gonna be either Bintec BeIP or "Digitalisierungsbox". And another thing, is 3CX also working with multiple standard non trunk SIP accounts i.e. Telekom? If queues are not really needed but the caller should get a greeting instead of ringing is this possible with ring groups?
