Skype, the world’s best-known VoIP app, is getting bigger and better, according to a SiliconANGLE blog post written by Maria Pila.

According to Pila, the recently updated version of Skype that just appeared on the Android market includes a crucial improvement: support for “two-way video calling on a widened range of current Android handsets.”

Pil;a noted that, at launch, only a handful of Android devices were supported, a common problem for video-related apps heading to the Android market.  But 17 more Android handsets are supported now, including Google’s own Nexus S, HTC’s Desire S, and the Xperia Neo and Pro from Sony Ericsson, all handsets that shipped with Android 2.3 installed, Pila said.

She noted that Skype v2.0.0.45 also includes support for SMS messaging.

Primus Telecommunications Canada has announced the availability of a new Session Initiation Protocol (SIP) Trunking service for small- and medium-sized businesses in Canada.

“Primus Canada Business Services, is a cost-effective alternative for business customers that want a flexible, reliable and fully scalable service,” company officials said through a press release.

The SIP Trunking will  especially benefit organizations that have already invested in a PBX  system and are now looking for a customized service to suit their needs, the company said.

“With SIP Trunking, companies get the voice-calling services they need with enhanced reliability to ensure that their calls are always answered, as well as a flexible and scalable delivery so they can change their service on the fly to meet their evolving needs,” said A.J. Byers, executive vice president of Business Services.

The VoIP company, Vonage, has introduced an iPhone app to compete with Skype. The new app, called “Time to Call,” allows users to make 3G, VoIP calls in the U.S. or Canada, or throughout the world using Wi-Fi.

The app does not require an account other than iTunes–billing is done through the app itself.

The app is not only free, but comes with a free, 15-minute phone call to practically anywhere in the world.
