Telephone titan AT&T(T Quote) has rung up a buy rating since March 2006. This is based on a number of positive investment measures, including robust revenue growth, net income growth and good cash flow from operations.

The company's growth has been driven by acquisitions. The completion of the BellSouth acquisition will generate higher cash flow, and AT&T expects its wireless segment, which now includes all Cingular and BellSouth businesses, to deliver double-digit earnings growth in 2007.
