Airtel did used to buy equipment indirectly, by paying dollars per capacity (erlang model) and letting the vendor figure out what that involved regarding equipment. But they moved away from this a few years ago to a more traditional model of just buying equipment, along with making some other major changes to the way they buy IT services as well.
