8x8 announced that an update to its Virtual Office Mobile application which supports business voice services over 3G is now available in the Apple iTunes app store for iPhone and iPod Touch models.

VoIP penetration among US businesses will increase rapidly over the next few years, reaching 79% by 2013, compared to 42% at the end of 2009, reports In-Stat. This penetration reflects companies having a VoIP solution deployed in at least one location.

It came out of nothing. Releasing a new version of iPhone SDK last week (along with the reveal of the iPad) Apple lifted 3G VoIP restrictions on the iPhone. Since then VoIP calls are not only available over Wi-Fi but also over cellular networks and more and more companies announces that their apps are now 3G friendly.

The new offering, Verizon VoIP Inbound with Local Originations, provides a local phone number with call manager functionality traditionally used for toll-free phone numbers.

snom, a developer and manufacturer of IP phones, has developed a new audio device that will allow SIP-based VoIP telephones to be used as an extension of any public address system.

After releasing VoIP enabled Truphone for Android earlier this month, Truphone today announced that it has updated the application to operate on Nexus One, which makes the company the first to provide Wi-Fi calling on Google’s device.

XConnect announced a trial of the first IP peering federation specifically for service providers capable of offering high-definition voice services.
