Google on Tuesday announced an alliance with Sprint to add the Internet giant's online telephone capabilities to mobile phones serviced by the US telecom firm.
Sprint customers will be able to have calls to their numbers simultaneously ring at multiple phones such as home or office lines or even be routed to computers through Google's free email software.
"This basically gives Sprint customers all the benefits of Google Voice without the need to change or port their number," Google software engineer Jacob Hesch said in a blog post.
Whether Sprint mobile phone users stick with original numbers or switch to Google numbers, Voice will replace Sprint voicemail and transcribe spoken messages for delivery by email or text messages.
