phones are not working at all

[23410]

I know nothing about this phone system. One of my employees set it up and is not available to help resolve the issue. I am left to figure it out myself. Can anyone help me troubleshoot? I am not receiving inbound calls or out bound calls

When both inbound and outbound calls fail at the same time on 3CX SMB, the issue is almost always the connection to your telecom carrier (your SIP trunk).

3CX provides the software, but an outside telephone provider supplies your phone numbers and minutes. You can refer to this guide Get a Number & Start Calling
