The fine folks at google never stop working. Good thing too, because you and I always benefit. Google Voice has expanded its reach once again. This time to include voicemail support for your carrier-issued number, along with other features like online, searchable voicemail, free automated voicemail transcription, custom voicemail greetings for different callers, email and SMS notifications and affordable international calls.
Every carrier in the nation must be pissed. The real interesting thing about these new options is that your messages follow you no matter what, even if you switch carriers to get some hot new device.
