After upgrading to v15 SP4, I went through the usual set up, choose a FQDN and that is all fine. The 3CX license key is correctly bound to that FQDN and the 3CX Mng portal works and on the dashboard specifies the correct FQDN. The problem is the webmeeting FQDN is different for some reason and I can't work out how to change it. As I say the main FQDN is correct and working. Does anyone know how to change the WebMeeting FQDN. Any help much appreciated.
