Voice over IP (VoIP) traffic has traditionally been carried over mainly fixed line infrastructures for a number of reasons, not least of which is the bandwidth and quality of service needed to hold a decent conversation, and mobile operators being narky about what traffic they carry. Is it finally breaking out into the mobile arena?

✹ VoIP is no longer just a cheap way to communicate. Consumers and business people alike don’t want to think about the data services they use, they simply want to whip out a device wherever they are and have immediate access to contacts via voice and messaging text as well as the capability to surf the net.
