Screen Calls From Various Google+ Circles
Send unwanted calls straight to voicemail by organizing your contacts using Google+ and Voice.
Google Voice has paired with Google+ to allow you to organize your contacts in a more comprehensive manner. You can coordinate how to handle each individual contact who tries to call you according to which Google+ Circle they’re in. For example, calls from the ‘Friends’ circle will go through to your mobile. While contacts calling from the ‘Random’ circle could go straight to the voicemail greeting. The greeting can also be customized for every circle.
If you’re looking to try out the new Google feature, simply click on the Groups & Circles tab on the Voice settings page.
