I have been using Google Voice since the it was Grand Central and it is just and amazing solution. I highlighted in an earlier post my 10 favorite aspects of google voice. Google has made some advancements that until now I just overlooked and never worried about. It is interesting because I have heard many complaints about this exact issue in a Google Wave thread. In order for this to work open the Android Market and download the Google Voice update. Also you either need a Google Voice account or know someone that can send you and invite. Here is the press announcement.
Using Google Voice for Android just got a whole lot faster. Until now, notifications of new messages appeared within 15 minutes of when they were sent. Today we are releasing a new feature called Inbox synchronization, which will notify your Android-powered device of new text messages or voicemails within seconds of receiving new messages in your Google Voice inbox.
To activate Inbox synchronization, open the Google Voice settings on your phone and touch Refresh and notification. Once you have selected the Synchronize Inbox option, you will start receiving faster notifications. Plus, Google Voice will automatically disable SMS forwarding to your mobile phone, so you won’t receive duplicate notifications.
Finally, we have made it much faster to interact with your contacts from the Google Voice app. Now you can click on any contact photo and get the option to quickly respond to voicemail by email or IM.
