| Try to set up GOIP for call divert: 
 Mobile 1 => GOIP(mobile 2) => VSP(ET263) => Mainland
 
 Scenario is user uses Mobile 1 to call GOIP(mobile 2&ET263 registered), after password(or whitelist) verification,  user dials a number like 0755123456 to call phone at China. It seems that this solution is not feasible for second dial. Invention of Asterisk is necessary.
