So I have a trial system running and I have everything working including a connection to our SIP gateway, extensions, firewall test OK, etc. I was able to get the 3CX client connected by emailing the config file and that is online and I was able to get linphone (A third party SIP client) connected and working. The problem is that when i try to make calls either on the 3CX client or the Linphone client I get errors: Error on 3CX client: The client window shows I am connected but says "CTI - No Phone Connected" When i try to make a call I get a pop up that says: "An error occurred whilst performing a call. It says I cannot use the FREE version with a phone that does not support CTI" "Contact your admin to install a vaiid license" Error on Standard SIP: The client connects perfectly "Not Found. 499 - It displays the Windows machine name and says "not found" All I need to do is get calling working and I am good!
