Tech Notes:-Using US Number In India Mobile And Making Free Calls To US

Recently I had a requirement. Need to call US whenever I require from India. I found the solution.Here is what you require.


1. Wifi enabled phone or 3G enabled connection-->I use BSNL 3g on HTC Touch t333
2. A free account from Voxalot.
3. Registration with IPKall for a free US phone number.They will provide you a number from Washington.
4. SIP client for your mobile. I use Portego.


1. Register for Voxalot account Registration is fairly straight forward.

2.Register for a free IPKall Washington State number. Use the following on the sign up page: Choose your account type – SIP, Choose Area Code for your IPKall Number – ANY, SIP Phone number – , SIP Proxy – “” (no quotes), Email Address – , Password – , # of Seconds to ring before hanging up – “120″ (no quotes).You will receive a mail from IPKall with your configuration

           SIP Phone Number: 6 digit number 
SIP Proxy:
Email: your email address
Password: password that you configured

3. Download and install Portego SIP client for your mobile phone from portsip

4.Configure Portego
UserName: Username that you received in IPKall mail . 6 digit number
Password: Password that your received in IPKall mail
SIP Server:
SIP Port: 5060
Domain Auth Name:
Username that you received in IPKall mail . 6 digit number
You need to select codecs G711U,G771A,GSM if not already selected

Once you are done with the configuration, click login. You are all set to use your US number on your mobile in India either over wifi or 3G.

One more enhancement that you can do is to use your Google Voice number to forward calls to your IPKall number.Its important that you use PortGo here because other SIP clients like Fring may not allow you to accept Google voice calls due to its limitations with keypad(You may not get option to press 1 once you receive a google voice call).

How it works

Google voice will connect any two USA numbers or a USA and a Canada number. IPKall will give us a free USA number so we can receive (and make web activated) calls from Google Voice. IPKall then takes that incoming Washington State number and turns it into the SIP protocol and delivers it to a Voxalot SIP address. Voxalot Maintains contact with your hardware or softphone to be able to deliver incoming calls to it as required.
