[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

Can SIP be used for consumer market devices or will it only exist in the enterprise domain? This seems like an easy question to answer - surely it is suitable for consumers as well. I met with a customer last month who is working on a videophone consumer product. Their company is specifically looking for a proprietary signaling protocol. The reason for this is: SIP is good only for the enterprise market I know for a fact that

IMS enables the speedy creation and deployment of new services (at least on paper). As such, it has been adopted as the architecture for next generation networks - this is true for mobile, fixed, wireless and cable networks. An important aspect of IMS is security, but I have a feeling that like current VoIP deployments, security is somewhat overlooked. On its lowest level, IMS security requires IPsec - this encrypts and secures the actual IP packets sent over the network.

[I went together on a business trip with Jacob Bridger, a colleague of mine. In one of our many discussions he raised his experience with the IP-PBX he has installed at home. I asked him if he can write it up for this blog and its readers.] Many of us see VoIP as a cheap alternative to the PSTN. Services like Skype, Vonage and others use VoIP to allow us to call PSTN numbers at the last mile using a

Around 5-6 years ago, we have started with our 3G-324M efforts. At that time, when we built the business case for a 3G-324M stack, we stated an opportunity window of 5 years only until this technology becomes obsolete. A lot of water have passed down the river since then, but the fat lady isn’t singing yet - and probably won’t in the near future. Some history 3G-324M is a protocol used by 3G mobile handsets for their video telephony needs.

When you work with standards it is hard to differentiate. Take for example the browser market. Not all browsers are created equal. Taking a look at the 4 major browsers on the market today, and trying to summarize each one in a sentence, this is what you will get: Internet Explorer - Largest “customer base”, not adhering to standards Firefox - Full of plugins, liked by developers and

Video as a means of communication between people has been with us for over a decade, but it hadn’t made it mainstream yet. It seems like there is evidence of that changing.Technology wise, we are almost there: We now have the processing power, bandwidth and knowledge of how to build a video system enabling people to interact in real-time and provide good quality of experience. Only problem is, video telephony is not taking off as much as it should, but

Video telephony as a technology is making its way to the consumer market. The next step is the set top boxes and the world of IPTV.Today, people around the world can use video calling on millions of 3G mobile handsets in Europe and Asia. There are issues with pricing, usability and quality, but I can never have enough of the smiles of my baby girl on my 3G phone. Video telephony on mobile handsets is just the beginning - in

Megaco is back for another round, like the phoenix, it re-emerges after burning to ashes. Why now? IMS, of course…Megaco, also known as H.248, is a standard used to decompose multimedia gateways. If you’re developing a large scalable gateway, with a lot of multimedia processing, then splitting the logic of the application from the “dirty” processing of the media itself is a wise thing to do. In such a case, the communication protocol between the logic and the media can be Megaco - and this is exactly what is done in IMS when developing MRFs (Media Resource Function). Now, prior to IMS, I’ve seen Megaco demand from customers fluctuating - every year or two, the demand lowers, only to rise again a year later. Now, Megaco, as the Phoenix it is, is rising again from its ashes for IMS - and it’s doing it gloriously. There are a lot of companies out there developing products for the IMS infrastructure - those developing gateways or other media servers are in need for Megaco. If you are looking for Megaco stack, then search no more.
