I am having a weird issue with with my iPhone. I have been using Google voice for over an year now and my ggogle voice number is configured to forward call to my iPhone. But I just noticed that when I call my AT&T cell directly and reject the call, instead of playing my ATT voicemail greeting, the message says that "The ggogle voice subscriber you have called is not available. And then in 1-2 mins I receive an email from google voice informing me of new voicemail. I had installed GV mobile app couple of weeks ago but that should not start routing calls to my ATT number to Google voice network. I have also checked call forwarding on my phone and it is disabled right now. This just doesn't make any sense. Is anyone having a similar issue?? I am on a call with AT&T CS right now and he is checking what is going on.
