Hi, Thanks for your reply. As I am running out of my minutes, I would like to use Google Voice for local US calls as it is free. So I registered on google voice and got a number. Now I have installed "Dial central" and logged in with my GV username and password. It picked up my GV number automatically. I also entered the call back number to my mobile. So if I dial any US number , it rings on my mobile. That confuses me. If i remove the call back number, I am unable to make any outgoing calls using my data ( like VOIP). I am sure i am doing something wrong here. Could you please explain me how i can make outbound calls ( just i make free calls from google voice dialer on my browser). Thanks again.
