Well after getting Google’s Click to Call to work nicely with calling cell phones I decided to try calling either of my Gizmo Project numbers.
No joy. It could not connect.
Next I tried my Skype In number and same result.
Update–I changed hotels and cities and it worked with Skype..Hmmm
Its possible that Google blocked further calls initiated by your computer because it saw \too many call requests from the same IP address in a short period of time (or perhaps you were calling the same listing with multiple numbers or calling across unrelated categories).
Any of these assumptions true ? 🙂
