What is Callback?

Callback first became popular, and lucrative, as a service when the great disparity between calling rates between International destinations, where it is cheaper for A to call B, than it is for B to call A, became evident and the opportunity for arbitrage was realized.  While downward pressure has significantly reduced the margins on calling between International destinations, opportunities still exists and new uses have surfaced on the web, in social networking, with mobile phones, and in the hospitality industry.  Callback can now be used on corporate web sites to engage casual web surfers as well as provide customer service, sales and support, where users are presented with a dialog window to enter their phone number to be connected to a company representative.  Callback is also popular on social networking and dating sites where users can freely engage with one another in a more timely and personal manner than e-mail and chat while avoiding having to disclose personal contact information until there is a greater level of comfort and trust.  Callback is also gaining popularity with mobile phones where the callback is triggered from a smartphone application and the subscriber can receive a regular inbound call and then be cost effectively connected to their international destination.  Mobile is still an area that offers a significant arbitrage opportunity and callback technology can help the service provider capitalize on it.  Callback is also a great compliment to other telecom services such as conferencing and the call center, where callback can be used to bring a participant into a conference or it can be used to conveniently call back a caller, who was waiting in queue, when the next agent becomes available.

It is quite easy for service providers to deploy a callback server as it can reside in a central location while providing callback services globally.  There are many types of methods that can be used to initiate the callback request including the web, telephone, mobile smartphone application, e-mail, SMS text message as well as an open API to make it possible for callback to be incorporated into a third-party product (e.g. predictive dialer, emergency notification, etc.) and since callback is device agnostic services can be offered to anyone regardless of their level of sophistication or access to advanced technology.
