Just got an AT&T number on straight talk but unable to make any calls using google voice. I have the google voice app installed and when I try to make a call using google voice, it tells me it cant make the call. It tries to make a call to a 916 number but I saw this same thing when I was on another carrier. Also when I try to text the ST number from google voice, it always returns saying it couldn't be delivered. Has anybody else run into this? Does anyone know if ST is blocking google voice? I can make normal calls from my ST number and can receive calls.
