For the past several years, our company has been investing in VoIP infrastructure. Today, I am capable of making video calls and joining audio and video conferences from practically everywhere - from meeting rooms to my work station, my laptop and even my mobile handset. Or as Sagee would say - “The shoe-maker does

It seems that in the last several years, the only business case presented by companies is advertising. Search? Advertising. Blogs? Advertising. Calls? Advertising. Entertainment? Advertising. Although advertising is a good monetization technique for some, it is not a ‘one size fits all’ solution. Let me first split the markets into two specific types: hunters and gatherers. I am not talking about prehistoric human societies, but rather about the concept of what we do

Once a year, RADVISION’s TBU division holds a road-show in Asia Pacific. In these events, we travel between different countries, meeting clients and holding seminars. Our road-show for 2008 starts today. Seminar in Taipei during the 2007 road-show Now, that the IMTC SuperOp 2008 event is over, it is time to look forward on what will happen in the next two weeks. The road-show is a very exhausting event - it spans four different countries, usually in less than two weeks. In each country, besides the frantic runs from one meeting to another there is a seminar. During the seminar we present the various market needs of the industry along with our solutions - all this is “seasoned” with live demonstrations. This year’s theme is “Development for innovative multimedia application for IMS/NGN”, in which we cover market trends, relevant protocol stacks, client and server frameworks and testing tools. The seminar is relevant for companies who are developing VoIP communication products. In the next two weeks, we will be traveling around Asia, with countries such as Japan, China, Korea and Taiwan on our tour this time. If you are around, you are hereby invited. Just drop me a message.

A lot of reviews have been done on Office 2007 - this is not going to be one of them. I just had the questionable opportunity of working with Microsoft Office 2007. It can be a very frustrating experience to anyone used to previous Office versions. Office 2007 can serve as a great lesson on how to plan new versions - especially when the customers are engineers. Our company has just migrated to Office 2007 this week. It has

[I’ve had a chat the other day with a colleague of mine, Danny Loeb, who is the Product Manager for our SIP Server Platform. As part of his work, he needs to deal with the multi-core trend and how that changes the architecture of his product.] Multi-core is all the rage these days. Or at least this is what Intel tell us - almost every month Intel arranges a seminar, workshop, training or some other session about multi-core here in

[Steve Rust, GIPS VP of Business Development was kind enough to provide his views on call quality and what that means on the audio side for this blog and its readers.] If you live in the United States you may have seen a television advert for Verizon where a guy wanders around the country to gauge how good his cell phone service is in different places. His tagline: “Can you hear me now?” is well recognized. Vonage is

No company today is capable of developing its products in-house without using 3rd party software. In most cases the process starts from outsourcing the operating system itself, continues with outsourcing specific protocol stacks and user interface engines, etc. These come from vendors which are sometimes called ISVs (Independent Software Vendors), middleware vendors or various other types of manufacturers.I came across Åse Stiller’s guest post on VisionMobile, where he recommends vendors build an end-to-end flowchart of how source codes of their

In the past month I have traveled the world: mostly Asia and Europe; meeting with over 30 companies. All engineering companies, some customers and others prospects. Different countries. Different mindsets. Different cultures. Different beliefs. Argentinean tango Photo: Alexander Zabara The intensity of it made me aware of the delicate Argentinean tango between vendors. Argentinean tango requires a lot of synchronization between the two dancers. The man leads the dance, deciding on which steps to make, building the choreography of the
