Skype is now reportedly the largest carrier of international voice traffic, something that has to be making waves among carrier planners. In fact, the Skype phenomenon is creating major concern about voice migration planning among network operators, in no small part because it’s believed that VoIP services like Skype will also quickly take hold in wireless when unlimited data plans come into play.
The big question for operators is whether to invest in 4G voice (IMS) or to simply focus on data and let current 3G networks carry voice traffic until users finally simply abandon traditional voice services. Some are considering their own overlay services based on simpler Internet voice technology, rather than IMS. We expect that the final verdict here won’t be rendered until the spring.
