it's easy to sign up for Google Voice. I just did a dummy sign up.
STEP 1. First of all, you must access via US proxy. You can use simple solution like a free Virtual private Network via
Get Behind the Shield! Hotspot Shield by AnchorFree you will get USA IP address and you do not need to make any browser/config changes on your computer. Simply turn on/off the connection with a button on your desktop.
When connected to proxy or US based VPN, follow to step 2.
STEP 2. Go to
http://voice.google.com/ and sign up for NEW GOOGLE ACCOUNTS (blue button). Select the country - USA when filling out the form. As you process you will be asked to select a number by area code, city name, or spelling a word. Please note that not all area codes/states are available with Google Voice yet. For example, Miami, FL area has no numbers available so far. After you select the number, you will be asked to activate the number by entering US based phone number. Google will call you there and you will enter the confirmation number you see on the screen. After that, your account will be activated.
STEP FOR NO USA NUEMBER. If you do not have any USA number that you can answer, you can get a free Washington-state based number from IPKALL.
FREE IP Calling with IPKall You will also need a SIP enabled phone to receive your phone calls at. The SIP phone will register witha SIP server, BUT NOT with IPKALL. IPKALL is forwarding-only service. So you can get a free SIP account with
Callcentric - VoIP Internet phone service and then use SIP URI FORWARDING to receive calls from IPKALL on callcentric. So you enter IPKALL number into google voice signup. Google voice will call you on IPKALL number which will forward via SIP URI into your callcentric account. You can also use other SIP services which allow to receive calls via SIP URI (from IPKALL, f.x.), such as
www.freeworlddialup.com or
Calling Card , Asterisk PBX SIP H323 termination A-Z, mobile sip voip , Nokia symbian mobile dialer, talkfree , Ringasia, icallhere ,linksys pap2
Sidebar - For example, your callcentric SIP URI forwarding will look like 177xxxxxxxx@ where 177xxx is your customer number. You enter this URI into IPKALL and you shoudl then be able to receive IPKALL calls on your callcentric account. You register your SIP phone or softphone into SIP server of callcentric. Please see help section on callcentric for setting up SIP URI forwarding and setting up your SIP connection into their SIP server. their help section shows how-to guides for a wide variety of SIP adapters, SIP phones, windows softphones and mobile softphones on Nokia, Iphone, etc.
