Buggy/unreliable software is indeed the same anywhere. But when combined with buggy/unreliable OS's, now we're talking about a solution that is REALLY buggy and unreliable. For example, if your software is only guaranteed to run at 3 9's, and your OS is also only guaranteed to run at 3 9's, then overall we're talking about a less-than-3-9's of a solution.
You can actually run packetized voice very reliably, and not just for toll bypass (although it is definitely true that toll-bypass is the easiest and most mature kind of packetized voice to do). The key is that you have to design things in a certain way to maximize your reliability. Many carriers like SBC use packetized voice with soft-switch signalling in certain parts of their network, and then you have packetized voice wholesalers like Ibasis that have massive available voice capacity and a good reputation for reliability. There was a huge amount of serious talk after 9-11 for Verizon and other carriers to contract for backup voice capacity through somebody like Ibasis in case their voice switches got destroyed again - as during 9-11, people saw that while traditional voice service was severely affected, packet networks like the Internet were still functioning, so in these kinds of circumstances, you could say that packetized voice might actually be more reliable than regular voice. But again, it takes very careful design to achieve this kind of reliability.
