A packet is a packet. But if you want your IP packets to carry voice as well as data, you have to look long and hard to find true business-class voice-over-IP services. Still, businesses are seriously considering VoIP services as a way to integrate their voice and data networks--adding voice to the growing IP data network just makes sense. Most VoIP services today consist of low-cost long-distance calling cards and bypass services aimed at frugal consumers who are willing to put up with choppy or distorted-sounding calls if it means reducing the size of their phone bills. But this is just the beginning; for service providers, corporate VoIP services eventually will be the big-ticket item.
