Free Calls and Conference Calls with all your facebook friends: http://apps.facebook.com/talkster/

It works like a conference call. You call your local number, the other person calls his/her local number. Both are charged local fees if the phone company charges.

To make a call, call the talkster number, and tell your friend to handup and call in his local talkster number. In the meantime, you wait online until your friend calls in.

Since betamax’s service is so bad and rates vary so much, so fast without updating website information. You might want to go for skype for international calling. But the only thing I don’t like about skype is that people have to use it with computers. People have tried to use it with asterisk. But I’m not sure how well it works.

Wakacall plan is from voipagain(VoipAgain.com).

It’s rates can be seen on http://www.voipagain.com/rates.htm and choose wakaCall or go to http://www.voipagain.com/waka30.htm directly. They offer different plans. Wakacall is one of them, which is currently active.

They offer free minutes to the free zones. To see the free zones, go to http://www.voipagain.com/rates.htm and choose wakaCall free zone or go to http://www.voipagain.com/wakacall.htm directly.

They have another free minutes policy which is also kind of tricky.

*FREE CALL Rules:

The voice quality not only depends on the destination, your network quality etc, but also the calling softphone/device. My experience is that eyebeam 1.1 is better than xlite 3.0 and BuzzSip. I have not tried it with devices.

There are one set of username/password for web login, one set of account#/pin# for calling account. To configure wakacall on sip phone:

For wakaCall Plan

Configuring X-Lite 3.0

Once X-Lite is installed on your computer, you will need to add the following Account Details.

You are now ready to start calling with wakaCall! 

Or you could try BuzzSip:

BuzzSip v3.2, our free & preferred softphone.

wakaCall also offer calling card method, which is good for people who want to call without internet. To do that, they could buy a local DID number and directed to their calling card gateway.

But you may need check the voice quality to make sure it’s good for you. The voice quality could differ a lot for different people.
