If it was a VoipO wide problem, you'd hear a lot of people complaining. But the overwhelming majority of VoipO users don't have any significant problems. A couple times a year, I have an issue with incoming or outgoing calls. I have a pretty complicated network. Everything is static IP addresses; QOS; port forwarding (For various devices). If I start to have any voip problems, I usually notice memory leaks either in my modem or router also. I usually reboot my entire network and everything works perfectly again. Basically; I've never had any significant issues with VoipO or ANY voip service I've had. And I've had no less than 3 different internet providers over the years.

Voip is still not as mainstream as many would like to believe it is. It is still dependent on the network it is connected to and the internet connection and ISP. Some day, if we can ever get QOS type service at the ISP/WAN/Internet level, voip will be able to become universally accepted and function better. "Same with video conferencing". But for now, those who know a lot about networking and the internet will have very few problems with voip. Those who don't know as much, or think they do, will still have some problems. If one provider appears to work flawlessly for an individual, that doesn't mean that provider is better. Simply means that service is more compatible with that individual's network, their ISP, and that ISP's routing.

What is going to change this for everyone; for the GOOD; is 4G cellular technology. "Why, pray tell?" Because currently, cellular voice calls are not processed on the same portion of cellular networks as data is. GSM/CDMA, 2G/1Xrtt, 3G, and now 4g/LTE are all different parts of the cellular system. Within the next few years, the cell companies will actually be processing their phone calls over the 4g/LTE data network. Basically, voip calls. Now that they have the bandwidth with 4g/LTE, they will be able to do this. Once they start doing this, the internet will need to be able to handle the CBR type of traffic like voice/video that is required for data that needs to remain constant and packets aligned. Once this is done for the big boys like Verizon and AT&T, other voice traffic like current voip providers, will have their packets processed much smoother.

My only concern is the evolution of cellular providers. With 4g service offering a lot more bandwidth and throughput, and cell providers like Verizon now offering the "Share Everything" plan where they offer unlimited voice and texting, the need for home fixed internet access like DSL and Cable as well as home Voice service will almost become obsolete. The only thing holding the cellular providers like verizon back from putting all home internet companies out of business is the bandwidth need at home for such things like netflix streaming, online gaming, and other high bandwidth. But for the average internet user, an unlimited voice, text, and reasonable data allowance can make the need for home internet and voip/POTS a thing of the past.
