Meanwhile, the company remains cautiously optimistic in its outlook for the fourth quarter ending in September. Avaya says that even though the fiscal fourth quarter ending in September is its strongest quarter, execs are holding with their cautiously optimistic outlook. The company forecast "higher sales expenses in the fourth fiscal quarter resulting from normal year-end increases in sales commission payments and a modest increase in marketing expenses as it drives to increase market share and strengthen brand positioning." Analysts expect Avaya to show a 16-cent profit on $1.05 billion in sales, according to a Reuters Research tally. Early Wednesday, Avaya rose $1 to $13.50.
