One major stumbling block to ISPs registering as VOIP VAS (Value added services) provider with the NTC is the draft ruling that requires ISPs to enter into an interconnection agreement with existing carriers.
Why is this a bummer? Well, carriers have been known to drag their feet for years. In the meantime, what would an enterprise do with all the capital invested in the VOIP service? And how will the delay affect the service levels and call rates? I wonder what PISO has to say about this? (hmmm.. that's odd, no entry after Nov 2005)
