DESCRIPTION 

UniBells.com offers a large variety of callback services based on various authentication models. Call-back is commonly used in countries where it is difficult to originate calls due to regulatory or service cost problems. In addition, call-back allows subscribers that travel to have global access to low long-distance and international calling rates anywhere in the world. For example, if you travel overseas and need to make a call, simply log into the UniBells.com web site and enter your current phone number and the system will call you right back. UniBells.com offers a large variety of call-back services based on various authentication methods. Among those methods are: Web, Email, Caller ID, SMS, PIN, and SMS DID. The most common call-back methods are SMS and Web call-back. Once the system calls the subscriber at his current phone, it prompts the subscriber for a destination number (if not already provided) and then connects the call.
