Your Google Voice : Global And Individual SPAM Management

Google Voice Spam Management http://snapvoip.blogspot.com/
Ever since I started using GMail, say for last 7 years, I have been largely shielded from spam that infects every other mail system I use.
There have been a few times that some spam gets through but I always, report those, preventing them from appearing in my inbox next time.
So same goes for my / our Google Voice accounts, there are some spammy calls that ring our phones and we again report spam.
You can activate your spam control by taking a few simple steps;

Global Spam Filtering

Global Spam Filtering makes it possible to automatically redirect calls, texts, and voicemails from any of the numbers in the Google database that have been identified as spam directly into your spam folder. To enable this feature simply:

1. Click the wrench icon and select Voice Settings.
2. Click the Call tab.
3. Check the box next to Global Spam Filtering.

1. 
   

If a number ends up incorrectly marked as spam, you can easily unblock it by selecting the message and clicking the Not Spam button in your spam folder.

And for spam individual callers management or completely blocking callers;

Spam from Individual Callers

If you get unwanted calls, you can choose to send the caller directly to voicemail, treat all calls from a particular number as spam, or block the caller. Follow these steps:

1. Go to your Contacts list in Google Voice.
2. Select the checkbox next to your contact's name.
3. Click Edit Google Voice Settings and select the second radio button under the 'When this contact calls you:' section, next to the drop-down menu.
4. Choose one of these options from the drop-down menu:
   
   • Send to Voicemail: None of your phones will ring, but the caller will be prompted to leave you a voicemail message.
   • Treat as Spam: The caller will hear ringing and then be prompted to leave you a voicemail message. None of your phones will ring. The voicemail will be automatically marked in your inbox as Spam, and you won't receive a notification for the voicemail.
   • Block Caller: The caller will hear a 'Number not in service' message when calling your Google number. None of your phones will ring. The call will be marked as 'Blocked' under 'History' and 'Missed.

AT&T Admits To Blocking VoIP In Its Wireless Network

No VoIP In AT&T 3G Network
According to the press release by xG Technology, AT&T has admitted to the FCC, the Federal Communications Commission, that AT&T blocks VoIP from the wireless networks. So blocking of Google Voice a while ago that it admitted has nothing to do but Apple's doing holds very thin. In fact no carrier in continental USA allows VoIP in it's wireless spectrums, even though it will save millions to consumers. In it's response to FCC AT&T argued that it needed to block VoIP to assure that revenues from its current voice plans would not be reduced by enabling mobile VoIP calling. 
“It makes perfect sense,” said Joseph Bobier, chief technology officer of xG Technology, “No U.S. carrier currently allows VoIP across mobile networks. Given the billions of dollars they spent acquiring spectrum, building and deploying their cellular networks, the economics simply wouldn’t work.  VoIP saves consumers money, but the flip side of this benefit is that this means less revenue for operators.  In fact, the only two major wireless carriers in Europe that allow mobile VoIP traffic added charges that essentially strip out the savings that VoIP delivers.”
By focusing on reducing the cost of the cellular network itself, xG Technology is a company that believes mobile VoIP can provide significant savings to consumers and still be profitable for carriers.  The company’s approach has been to develop a network that uses free spectrum instead of the carrier paying billions for licensed spectrum.  This translates to lower costs that can be passed onto the consumer. 
“By contrast, xG Technology recognized that Internet based calling—VoIP—will be the technology of the future and we designed our mobile system from the ground up with that in mind.”
