I am in India and my husband is in U.S. I checked my dh's phone details. he had called some no. in midnight. the conversation lasted 30 min almost. When i tried to call, it says "thank you for using vonage . the no. you are calling from is not register vonage no. please register your no to vonage account"

for 3-4 no. it says same thing.

does anyone has any idea wats going?
