Google has announced plans to offer a free unified phone service. The "Google Voice" service will offer users a universal phone number capable of routing calls through to mobile devices, landlines, and desk phones. Google Voice allows users to listen to voicemail messages and choose to have new voicemails automatically transcribed. This allows users to see transcriptions in their inbox and will be able to search for voicemails. Transcriptions are also included in email and SMS notifications. When somebody sends an SMS to a user's Google Voice number, that SMS will be relayed to forwarding cell phones and stored in their inbox. Users can reply from a computer or from any mobile phone and the conversation will be saved in their inbox. Users can then read through the conversation thread and search for past messages.
