Telecom equipment maker Nortel is focusing on making India its Asian hub for network managed services. To begin with, the Canada-based vendor has enhanced the capability of its network operations center in New Delhi to make it the Asian NOC for supporting customers in the continent. To cash in on the increase in Internet protocol telephony traffic, especially by BPOs and ITES providers, Nortel is also looking at rolling out proactive voice quality management, which ensures better quality of IP telephony deployments.
