All too many voice-over-IP (VoIP) vendors want to sell you "complete solutions" - from the telephone on your desk and voice mail to the wide-area connectivity between your sites and to the public switched telephone network (PSTN).
But I've seen that unless the customer and vendor are thoroughly experienced and check every detail, complete VoIP systems can be recipes for failure.
Enterprises that have had problems with VoIP may have done so because they jumped into a covered wagon and leaped into the technology frontier, rather than first learning to ride a horse.
