Jajah, an international VOIP service, launched its custom iPhone interface for the iPhone on Thursday. Apple iPhone users can access the service via Wi-Fi or EDGE with Safari, enter an international number and pay low VOIP rates for an international call.

No contract is required, and international rates are a fraction of what is normally charged from a land line or mobile service.

The user connects to iphone.jajah.com and enters the desired international number. Then there is a call back to the iPhone over the EDGE network and the two numbers are connected via VOIP for the international connection. For example, calls to any land line from an iPhone the U.S. to Germany are 3.3 cents/min. and 20.6 cents/min to a cell phone in Germany.

Because the call is set up between two standard phones, this is not like Skype. It could be useful for business people who want a low cost, easy access mechanism for international calls from anywhere in the U.S.

Calls between Jajah members are free.

Users must sign up with an e-mail address, an iPhone phone number, and registration is free. International call charges are billed through a Jajah account and can be paid, for example, with a credit card. The duration of the local portion of the call is part of the user's monthly minutes on the AT&T iPhone plan. There are lengthly terms of service worth reading.

The original service can be launched from any personal computer by creating an account and logging on at jajah.com. The call, however, is always between two standard phones.

A free trial for five minutes duration is available.
