I agree with your sentiment about the Corporate VoIP market. It is actually larger than the Carrier VoIP maRKET though comes with higher sales acquisition costs. The 800 pound gorilla in Enterprise VoIP is Cisco of course, and they embedded SBC capabilities in the branch office routers. Having said that, I believe AcmePacket will capture the Fortune 1000 market as they migrate to VoIP due to their platform scale and feature set. This market is not yet factored into WallStreet's estimates and is all upside in terms of EPS growth.
