I’ve tried Search Engines on the Internet as well as some of the leading magazines available in India, but I havn’t got to any specific information on the actual cost benefits as well as requirements for implementating VOIP(Like VOIP phones etc) and their pricing. I do know that SIFY, BHARATI, Tata’s are the leading Service providers but has Voip really been implemented somewhere and if so then are there any post implementation case studies as regards the same? Could someone please provide some articles or tips or links that would help me answer my queries…
