`Call it the “one numberto rule them all” service. Google Voice, which goeslive in
`a few weeks, is supposedto let friends, relatives, and business contacts find
`you whether you’re at your desk, on a business trip, or vacationing in Peru.
`Tests carried out over the past few days suggest that, despite a few glitches,
`it could well live up to this promise.
`
`Message me: Google Voiceis aunified messaging service-use one numberfor all of your phones.
`
`Users will soon be able to register, sign up for a phone numberin a local
`area code, and add multiple landline and cell-phone numbers to an account.
`When someonecalls a Google Voice phone number,all the registered
`phonesring at the sametime.
`
`Theservice takes several telephony technologies—voice-over-Internet
`Protocol (VoIP), voice transcription, and call routing-and connects them to
`the Web. Other Internet phoneservices let you play voice-mail messages
`on a computeror recordcalls, but Google Voice is a step towards unified
`communication.It’s the voice equivalent of an e-mail address. Once you
`register a number, the idea is that you never have to worry about which
`phone you are using, even if you switch offices, homes, or cell phones.
`
`Google Voice doesn’t actually host phone calls. Instead, when you make a
`call, the service calls your own phone, and then dials the number you want.
`Like other Google services, it taps a vast cluster of computers to offer extra
`services, such as voice mail and call recording. Becauseit is entirely IP-
`based, the service is always “on the line,” meaning you can access it at any
`time, for example, by pressing 4 to record a currentcall.

`standard telephoneline| and SIP |the digital
`line] services. I would expect their data
`centers will have large racks of these,” says
`Rob Enderle, founder of the research
`company Enderle Group. “Google Voice translates an SIP address into a
`phoneline, converting the digital data stream to an analog stream and then
`allowing the line to connect.”

`
`Time delays, also knownas latency, remain a serious problem with VoIP,
`but if any company can handle tremendouscall volumes, expand computer
`clusters quickly, and reduce latency issues, it is Google.
`
`Google Voiceis also largely about unification. No matter which phone you
`use, there is one portal for all voice-mail messages. You can play them on
`the Web, save them as MP3 files, and even post a voice-mail message on a
`website using an HTML embedfeature. Conferencecalls are also easy: just
`answer an incomingcall to addit to the currentone.

`Options, options: Google Voice users can quickly enableor disable anyof their phones.
`
`Phone numberavailability is very good, even in remote areas. During
`Technology Review’s test period, there were never any connection
`problems, even with Google Voice originating calls from Google data
`centers. Enderle says there may be issues with reliability in the future,
`noting that Gmail does not have a great reputation for being available at all
`times.
`
`Whena caller leaves a voice mail, Google Voice automatically records and
`transcribes the message, then sends the transcription to you via e-mail. The
`transcription service uses technology developed originally for voice search.
`Enderle notes that the voice-recognition service has a hard time with
`accents and ambient noise, and does not interpret local vernacular-words
`not found in the dictionary-accurately. In our tests, most transcriptions
`were about 50 percent accurate-the service missed common phrases such
`as “checking in with you”andfailed to understand some city names and
`more-technical words, such as “convergence.” The speech-to-text engines
`employed will likely improve over time. One complaint: you can record
`incomingcalls, but not placed calls. And recorded calls cannot be
`transcribed-transcription only works for voice mail.
`
`Google Voice lets you send andreceive text messages-—again, by routing
`them between existing carriers. You can viewalist of every SMS message

`history of placed, missed, and recordedcalls. You can also import contacts
`from various address books. And you can easily disable one or more phones
`using a feature called Do Not Disturb.
`
`Google Voice has room for improvement, of course. You can’t “daisy chain”
`phone numbersso that the service tries one number, then another. Security
`is another potential issue. Recently, hackers showed that a caller could use
`Google Voice to tap into the services on a cell phone by spoofing the codes
`used to identify calls and messages sent over the Internet. Sara Jew-Lim,a
`Google spokesperson, says the company plans to add a default PIN to
`Google Voice; currently, a PIN is available only as an option.
`
`Overall, Google Voice is worth considering for anyone who wants to view
`call transactions on the Web, uses multiple phones during the day, or needs
`to record phone conversations. It’s a handy way to unify all voice
`communication, while trusting that the number you pick today will be yours
`for years to come.
