Call gets disconnected right after it is picked up

[ndmehta19]

I have installed OBi200 in India. It is connected with Netgear modem/router combo. Lately when I call from US to India and my dad picks up the call in India, call gets disconnected right away.    However when he can make call to any number in US. btw we are using Google voice. Any idea why is this happening? How can I resolve this issue? Any help will be greatly appreciated.

Thanks in advance!!
