I added a Google Voice number last year, and it worked just fine, ringing to my cell phone. I haven't changed anything, but I think because our organization went through this migration to Google Apps it is somehow orphaned. I can't log on to it, and each time I try to using the email id which was used to set it up, it keeps trying to get me to set up a new Google Voice account.
The phone number is still in service, but it just rings directly to voice mail and no longer forwards so something is all confused and I can't log in to check. I am lost in Google Apps land.
