Is VoIP service the stepping-stone to full IMS deployment?
The IMS optimist would say absolutely yes! IMS is simultaneous SIP-based voice with data or video. The pessimist would say yes as well, but add that VoIP would have to be bundled with something else in order to move IMS along. But that something else is likely to be content that has to be delivered by a non-telco. Also, an IMS OSS/BSS will be required beforehand, and that is not here yet.
