First you need a team that is highly familiar with VoIP, Asterisk, SER, CCM, SIP, IAX, H323, etc. That's not something a few posts on a mailing list or even reading some books can give you. You need people who are very familiar with these technologies and have hands on experience. If you are trying to do this yourself first study TDM telephony, then study basic networking (detailed however, understand how TCP/IP and UDP work, etc, etc) and THEN study VoIP. I would expect that to take you at least a year. Once you have that then you have the ability to put a system together once you have that system together then test the hell out of it, until you think that customers would come to rely on your service (product).
