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.

voip-weblog.com notes that voice over ip hardware manufacturer Grandstream has released it’s new all in one VoIP PBX.

The Grandstream GXE502x moniker actually refers to one of two new products, the GXE 5024 and the GXE 5028. Both are IP PBXs, the 5024 having 4 analog extensions while the 5028 has 8. Both designs allow for 100 registered VoIP accounts, 50 simultaneous calls (presumably dependent on bandwidth) and a 20 seat conference bridge. Flash memory storage is utilised for voicemail.

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

Alkahest has an interesting bit on the ‘pros and cons’ (but mainly cons) of Voice over IP in what sounds like a large oganisation when you have to switch over to using old kit that doesn’t support QoS in quite the way you need.

QoS or Quality of Service is a prioritisation concept for network traffic which is especially critical for Voice over IP. If your network packets can’t get through then neither can your calls.

The point is also made that your VoIP suppliers, if the must also be your support, must be good at actually helping you rather than just selling you products.
