revolutionise the customer calling experience," Bharti Airtel President Enterprise Services David Nishball said.
Besides the firm plans to extend its service in two more countries by Q1 of 2008-09, he added.
The CallHome services would have a Hotline service, which would enable users to configure up to 10 of his most frequently dialled numbers with a single-key access dial. It would also introduce value added services such as astrology, cricket and others soon.
