The presence of VoIP and WLAN on a Nokia Series 60 smartphone also means that near a WiFi hotspot one can even make completely free phone calls, which might come in handy mostly during trips abroad. Nokia smartphone came preinstalled with all required components for a VoIP software for a long time, but the latest software, S60 3.2, has no SIP stack (Session Initiation Protocol) for some reason, so those applications that were based on the SIP implementation of 3rd Edition Feature Pack 1 for example, won't launch at all. This of course doesn't mean that we won't be able to make free VoIP calls on a Nokia N78 or N96. It just means that software developers will have to create their own SIP stack implementations. The popular Fring, for example, already has a solution that works perfectly on Nokia 6220 Classic, which is based on S60 3.2. Eseries models are expected to contain all necessaary components in the future, as the business sector makes use of the possibility of cheap VoIP more and more intensively.
