Sprint Expands SIP Trunking Availability

SIP trunking services deliver voice calls from telecom providers to companies over IP data connections. Feeding their traffic directly into IP PBXes on the companies' premises, such services can bring considerable benefits. Sprint began offering SIP trunking to companies using Microsoft's Office Communications Server 2007 R2, an IP PBX software package that runs on Office servers, in February of this year. Now it's making the service generally available to business customers.

Ribbit Contributes Voice Conferencing, Messaging to Google Wave

Google's long anticipated Wave online collaboration tool is going live with voice functions supplied by Ribbit. Wave lets users communicate via rich text, maps, photos, video and other means. Ribbit's contribution will let them talk and exchange voice messages as well. As such, it makes voice communication an integrated part of a larger collaboration process.

CallSpark Offers Mobile Calling Search Engine

A mobile phone's built-in address book has limited usefulness. For instance, it only allows users to call people whose numbers they've already entered – which means people they know well. Directory assistance, on the other hand, is about reaching people or establishments one knows almost nothing about. But there's no easy way to deal with the vast territory in between – to reach people one knows only casually, or to learn more about people and companies one knows almost nothing about. San Francisco-based CallSpark, which presented at the recent DEMO conference, is trying to fill that gap.

OrganIP Turns Social Networks Into Phone Books

One of the more elusive dreams of emerging VoIP services is integration with social networks. The idea is compelling: if tens or hundreds of millions of people make calls to their social network "friends," someone will be able make a lot of money from it. So far, though, no one has had much success in appealing to such users. A startup that presented at the recent DEMO conference is trying to change that. OrganIP, run by France-based Digitrad, is trying to turn social networks into giant phone books.

AT&T Call Blocking Attack Reveals Google Voice Structural Problem

AT&T's recent letter to the FCC about Google Voice was obviously disingenuous. It tried to link network neutrality, a key Google crusade, with Google Voice's blocking of certain calls. In reality, there was little connection except the politics involved: The real goal of the communication was to paint AT&T as on the side of network openness, and Google as on the opposite side. But the letter did inadvertently bring to light a potentially major weakness in the Google Voice model: the fact that the free service has to pay to have its users' calls delivered to their destinations on the PSTN (public switched telephone network).

Mobivox Acquisition Adds Voice Interface to SabSe's Portfolio of Services

It's clear that many VoIP companies aren't meant to be standalone telecom businesses – they function far better as providers of features and capabilities to other telecom businesses. The latest example of this is SabSe Technology's acquisition of Mobivox. Although Montreal-based Mobivox offered cheap VoIP calling services of various types, what set it apart was its so-called voice-activated user interface, or VUI. The interface let users dial by speaking rather than pressing keys – a significant benefit for mobile talkers. The addition of this capability will boost the attractiveness of the array of services SabSe is offering worldwide.

Iotum Streamlines Calliflower Conferencing Service

VoIP-based conference calling is radically different from the traditional variety. The ability to integrate an IP-based service with Web and other applications transforms the experience for user and organizer alike. At a minimum, it can provide onscreen interfaces, and various other collaboration and communication methods besides voice. Iotum has been steadily upgrading its Calliflower conferencing service since its June 2008 introduction. And it has just added several new features that make the service quicker and easier to use, particularly in large conferences with plenty of outside participants.

OnSIP Adds Browser-Based User Interface to Hosted PBX Service

Hosted IP PBX services have long had a shortcoming compared to premises-based solutions: They didn't offer onscreen call-handing capabilities. Premises IP PBXes typically have fancy "dashboard" software that runs on users' PCs. It lets employees see who's on the phone, click to call, drag calls to transfer and things like that. Now hosted providers are getting into the act. Vocalocity introduced a browser-based dashboard in April. And Junction Networks' OnSIP service has just introduced its own call-handling interface.

Skype Adds Cisco SMB Interoperability

Skype business announcements are coming fast and furious these days. One big one was the introduction of Skype for Asterisk earlier this month. Others are the result of the introduction of Skype for SIP beta service in March. ShoreTel was the first to announce certification of its IP PBXes with that service earlier this month. SIPfoundry followed with certification of its sipXecs product about a week ago, and now Skype has added the biggest name yet: Cisco.

HP Introduces Cheap SkyRoom Video Conferencing Software

It's old news that video conferencing is increasingly replacing business travel, as companies do everything they can to save money during the recession. But it won't help much if the conferencing system costs tens or hundreds of thousands of dollars, as some telepresence products do. Hewlett-Packard has just introduced a product that attempts to solve that problem. Its new SkyRoom desktop video conferencing software costs a mere $149 per copy.
