Martin Sauter for WirelessMoves has written a brief article highlighting the risks of using unsecured VoIP services on public WiFi hotspots.

He points out that quite often, by default, your communications over a public WiFi hotspot are not encrypted and that goes for the voice stream too which could be passively lifted from the airwaves and replayed.

What do you talk about on your Voice over IP calls and would you be concerned if a third party knew?

Om Malik of GIGAOM has written an article about how he replaced his regular land-line based telephony with a voice over IP service from UK based Truphone.

Phone Boy Blog has an article detailing his three major gripes with using VoIP on mobile phones (within the USA)

His biggest gripe appears to be that there are no cost savings available presumably due to the cost of data plans.

I’d also probably add to his list to include potential communication interception vulnerabilities when using WiFi enabled phones on open hotspots.

Internet telephony company JAJAH is creating a native voice over IP application for the iPhone to be released later this year.

No word yet as to whether the JAJAH offering will allow the iPhone to utilise VoIP while also using other applications – a sticky point for Apple as the SDK does not directly allow for multitasking of ‘third-party’ applications.

The JAJAH native iPhone VoIP application is expected this summer.

Nokia just has announced it’s new 6300i handset.

The 6300i, developed (inevitably) from the Nokia 6300 now includes WiFi connectivity and a Voice over IP capability. Nokia’s developer site suggests that the handset will communicate on the SIP protocol for VoIP with the potential to make such calls over either GSM or local WiFi networks.

The 6300i is set to ship to ‘select markets’ in the second quarter of 2008 with a MSRP of €175
