AT&T has announced its AT&T Office@Hand app for iPhone.

The mobile PBX application is expected to allow small businesses with an existing wireless account from AT&T to configure and manage their office phone system from anywhere.

The communications company said the app works with existing mobile or fixed-line phones.

It offers professional phone system features such as auto-receptionist, multiple department and employee extensions, voicemail, and faxing, said the company, adding there is no hardware set up or technical skills required to use the app.

AT&T Small Business Product Management vice-president Ebrahim Keshavarz said small businesses and their employees are on the go more than ever before, and it’s vital that their customers can reach them whenever and wherever they are.

Keshavarz said, "The Office@Hand app is the ideal tool to drive mobile productivity for small businesses, connect their workforce, and enhance their company’s image by taking their communications into the cloud."

The app is available now on the App Store.
