I believe you are talking about the 3cx platform not Skyetel. I am logged into 3CX but very limited ability to change anything here. No real menu options that allow me to make the change you have depicted above.
Yes. It previously worked and now hasn't worked for months. Continues to say to call back later that the system is temporarily down. I submitted a ticket to Skytel. No representatives available to answer call.
I did check our voip provider (Skytel) and they are stating that there are no outage issues. Sounds like I need to contact them anyway since this is not a 3CX error message.
Can anyone give me a hint on where to start here? We aren't receiving any calls and we have paid for the service. Any assistance would be really appreciated! EO
