I bought an OBI. When in the road the idea is to call from my cellphone to my OBI Google Voice, get access to the landline and make calls overseas. Somehow when I press 2, it says service is unavailable, despite the fact that the landline works perfectly well if I use the phone.
Assuming it works, I have read certain technicalities regarding calling setup. The vast majority of my calls are overseas, thus I would need to call like 011- and then country codes+ area code+ phone numbers. How can I set it up for various country codes where each country has different number digits variations (from 7 to 11)
Thanks.
