Do all devices at that location have the problem—including mobile phones or hardware phones? If so, you—or whoever is responsible for the network—need to dig a bit deeper into the issue.
If hardware phones or mobile phones on the same network don't have the problem, then something on the clients is causing it—antivirus software, for example.
It’s still in the same place. Select the queue in the panel, and—provided you have the correct permissions—you can log agents in and out. There is surely a way to handle this via the API.
If you dont have any access to your pbx, than you cant do anything.
You didnt had admin access before? How are the phones connected to the pbx? If you have the free one hosted by 3cx, you cant use desk phones with it anymore.
Sorry, i need to edit my post...
Sure you can connect from anywhere... You can reboot it from your customer portal or from the webclient with admin access.
