Viruses and computer hacking have become common terms we all hear regularly in news reports and online. And while the concept of a virus is easy to understand, mainly because we are all taught how biological viruses work in our own body, it’s difficult to understand exactly what is going on during an attack inside your PC. What we need is a realistic visualization of exactly what is happening as an attack happens, and how […]

A spike in attacks against IP PBXs that started last fall shows no signs of abating, spawning speculation that those responsible have tapped into botnets and cloud computing resources to carry out their illegal activities. According to separate security reports from Cisco and Sipera’s Viper Lab research arm, the exploits are carried out using techniques that lend themselves to the interpretation that the attackers are tapping into broad resources that make their work more effective. […]
Regular attendees of the Enterprise Connect conference (formerly VoiceCon) couldn’t help but notice that this year everyone was talking — and talking more seriously — about implementing session initiated protocol (SIP) trunking. Although other conference topics such as Unified Communications and mobility may have been more glamorous, SIP trunking was often in the background as an enabling technology that can make those things work, or work better. SIP is an Internet standard for establishing and […]
It’s hard to imagine, but roughly 10 years ago as VoIP was being rolled out corporate networkers were quite concerned about the security of VoIP. As we faced a move from voice going over a traditional (and, by the way, unencrypted) network, there was concern that VoIP would be much too easy to eavesdrop on – especially if it traversed the Internet. We’ll leave the question of whether “legal intercepts” as a political and civil […]
IP-based phone systems offer better convenience and expandability versus traditional PBX Small businesses have so many more options now when it comes to business technologies, many of which have evolved to meet the specific needs of smaller companies. Even Voice over IP (VoIP) phone systems are now well within reach for companies that are looking for enterprise features on a small business budget. An IP-based voice system provides a business-class phone solution that is more […]
Traditional telephony may be replaced by newer technology due to an increase in the use of voice over IP (VoIP) in businesses. Sales of VoIP phones are mainly to businesses, according to In-Stat. Norm Bogen, vice-president of digital entertainment research at the firm, says the technology allows telephone systems to be used for “more advanced communications.” However consumers IP phones have yet to reach the consumer market. Apart from technology roll-outs from service providers and […]
A report has found that many businesses are turning to cloud computing in an effort to control costs Companies are increasingly turning cloud computing to enhance productivity and increase their return on investment (ROI), according to a report from Fonality. The “2011 Small and Medium-Sized Business Communications Plans and Priorities” state-of-the-market report polled professionals considered to be on the “leading edge” of technology adoption. Respondents emphasised that cloud-based business applications or AaaS (Anything as a […]
Just five years since mobile VoIP services were first introduced, it is on the cusp of moving beyond an inexpensive alternative for making international calls to becoming an integrated component of unified social networking services, says research house In-Stat. The coming years are expected to be transformational as mobile operators and associated players work out how to respond to a forecast of nearly 139 million mobile VoIP users by 2014, say analysts. “Mobile VoIP is […]
As your organization relies more on cloud-based applications for productivity and business success, you must be increasingly vigilant against Web-borne attacks. As sensitive data now migrates between corporate data centers and cloud data centers beyond your network perimeter, you can no longer think only in terms of network security, but instead must shift focus to information security. Three overarching, interrelated trends — cloud consumption, virtualization and mobility — present themselves as key industry themes for […]
In a sluggish economy, businesses, particularly small and mid-size companies, are doing all they can to trim costs. And one big cost savings many are making is to switch from costly landline phone service to the less expensive Voice Over Internet Protocol (VoIP). Although VoIP is ridiculously cheap, (think Vonage, Ooma, etc.), it comes with its own set of problems – particularly when it comes to security. The number of hacker attacks against VoIP systems […]
