Feature Call with Spark

I can login Spark with Server. But i can’‘t feature ‘‘Call’’, when i call to another number it’'s show “Your connection was closed due to server error… Would you right to Log bcak up?”. I want to know how i must config about server for Spark to call?

Thank you

Hi diff,

are you using Asterisk or how should I understand your very short post? Is the server running fine except of the Asterisk add-ons?
