Free Call Forwarding With SIP Tutorial- Part 1

This is another must read post, perhaps the best post written in the last 6 month. If you miss this tutorial, you will need to pay for call forwarding services. This tutorial will enable you to make unlimited call forwards to various destinations for FREE. This hack/workaround will work for people calling from India, Pakistan and any other destination as long as you have a PSTN gateway number and SIP service enabled.

We will try to make this guide as extensive and clear as we can. I hope you understand the steps and do not miss any. Please read the steps carefully, if you miss any of the step the hack won't work.

This hack will work with any provider including tpad (with PSTN numbers). I will first explain how you setup the free call forwarding facility and then we will see how people can call you.

Lets start with the tutorial. This tutorial has multiple sections. I want you to understand how the whole things works, since it will be easier for you to mix and match these parts to create a different solution from this.

First Section- Defining a Forward Facility with PhoneGnome.

1. Register your CellPhone/HomePhone with PhoneGnome
2. When logged into their website (PhoneGnome) go under the features tab and activate Remote Access. Edit the settings to Ring SoftGnome with Home Phone:Active by ticking the box. Now save.
   
3. On the same screen, Click View Sip Settings to see Sip Username, Password, and Sip proxy. Store it somewhere or keep this window open.

Now your forwarding is setup. Call forwarding is limited to Argentina, Australia, Austria, Brazil, Denmark, France, Germany, Greece, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Singapore, Spain, Sweden, and United Kingdom. Also includes Moscow and Saint Petersburg, Russia; Kuala Lumpur, Malaysia; Seoul, South Korea; Taipei, Taiwan; Monterrey, Guadalajara, Mexico City, and Puebla, Mexico; Excludes Alaska and Hawaii.

Second Section- Setting up SIP Gateway

Note: We are not considering voxalot for this exercise since voxalot will be a paid service from July 16. We will be using gtalk2voip to replace voxalot.


1. logon to your Google talk messenger (Download Google talk if you don't have it already). Add service@gtalk2voip.com in your buddy list.

2. open the chat window with service@gtalk2voip.com (You can register with Gtalk2voip and ask for invitation) and type HELP in that chat window & it will give you the list of text command which u can use, and at the last of this list it will give u Your personal account page URL .

3. Go to your personal account page and click on Define your own SIP providers and click on Add to define your SIP provider.

4.
Host = sip.tpad.com
Port = 5060
Your User Name = your tpad username
Your Password = your tpad password
Techprefix : +
select Reg. to SIP and Enable option and save ur information

5. Now click on "Define your dialing plan ".

Note: If you already have Phonegnome added as provider then no need at add it again. go to step 6.

Add Phonegnome as your provider with PhoneGnome SIP settings.

Username : (ur phonegnome username ex. soft12345678)
password : (ur phonegnome password)
Host: pgp01.televolution.net
Port : 5060
Techprefix : +
select Reg. to SIP and Enable option and save ur information.


6.Now click on "Define your Follow-Me number or SIP URI" and in Follow-Me phone number or SIP URI: type your complete phone no. with + countrycode which u have given in phonegnome account. ( ex. +4921712345678 where +49 is country code for germany).
7.After some time in your SIP provider list, the status of your sip provider status should be Registered, if not so logoff from your gtalk, and login after few sec.

Now your VOIP Gateway is Setup.

Section 3: How can someone call you?

There are two ways to call you, either via PC (tpad to tpad is FREE) or via PSTN. PSTN will be most popular method to call, so lets consider this in our example.

Consider that your brother in Mumbai wants to call you in Germany. Lets see how he can do it.

1) He will have to call Tpad's PSTN Gateway number(Gateway numbers are available in many countries, check the list), For Mumbai: 0 2228665454
2) They will hear an automated message "Thank You for calling, please enter
the number you wish to call" <--------- (Tpad is going to change this
message and make multilingual soon)

3. They then dial YOUR personal 7 digit Tpad Number e.g 1124139 and it will
take 5 - 10 secs to connect (depending on number).

4. Now this call is converted from PSTN into SIP will terminate first at Tpad SIP Server, however since we have forwarded your Tpad account to your phone via phonegnome, you phone will ring.

5. Now make Free calls unlimited times with this FREE forwarding method.

This will save your money on forwarding your call to your phone. The only cost is local call rate to connect to PSTN gateway which is Rs.1.

This workaround/Hack can be used across providers who provide PSTN gateway numbers or for that matter any provider offering SIP service.

Please let us know any specific provider whom you want to hook up on this free forwarding setup and we will try to provide you with a tutorial.

I would like to thank Yogesh (Germany) & Vishnu (Ireland) for their help in achieving this solution. Yogesh has worked with me for hours to figure this out before we knew vishnu already did it :-). We have now formed a new team me, Yogesh and Vishnu who will be working to find new exciting free solutions.

Please post your comments, questions and success stories. This hack will rock the VOIP industry!
