Hi All, I have a customer who has been using ADSL for their 3CX calls and the connection has been really bad. The customer has purchased a 4G connection and its working really well for internal clients. They also have about 5 devices which have 3CX phone on Android. These remote phones have stopped working as the DNS settings on the customer's hosting server was pointing back to the static IP address. Has anyone tried to use remote devices using a 4G internet connection?
