Hello, I'm tryin to configure overvoip.net Voip Provider on my 3cx phone system. I configured the provider with the Generic Voip Provider wizard. When I dial an outside number I have a dial tone, the IVR comes on, and everything seems to work properly. When I dial a US number I'm connected through with out any problems, sound quality is perfect. When I dial a European number, the IVR comes on, tells me the call is being connected, but then tells me "All circuits are busy, pleae try your call later, error 4011". I'm puzzled, initial connection with the Voip Provider has no problems, I can make calls to the US with no problems, which would mean the configuration is ok. Any ideas on what this error means ??? I really need to solve this so please help !!! Leandro.
