 雯雯,
 
 I'm currently setup the superdial already. But it just seems take a while (~5 - 10 sec) to check if the truck is "failed". So, for that 5 - 10 sec, I got "dead air" on my phone. Then I will get ringing tone again once it jumped to the working trunk. That's why I try to eliminate the dead air.
