Bharti Airtel, India's leading telecommunication firm, sees more network outsourcing activity in Indian telecoms, a top official said on Monday.

"I can say more of such outsourcing will happen," Bharti's Chief executive Manoj Kohli told reporters at the World Economic Forum.

In April, Bharti signed a five-year managed services deal with Alcatel-Lucent, worth $500 million.

Industry-wide average revenue per user (ARPU) will continue to fall on rising competition, but the ongoing price war is only a short-term phenomenon, he said.
