FaceTime is a new service offered by Apple on their iPhone 4. It provides mobile video calling, mainly for consumers. From the moment it launched, we have seen a rise in requests coming from vendors to build similar solutions with their devices, which means that a hectic year is ahead of us. If FaceTime (or mobile video calling) interests you, then you might want to consider spending a bit of time on reading the list of resources I’ve collected from

In our “hidden challenges in developing HD video telephony products” webinar there was a really active Q&A session. As I promised after the webinar, I will be covering a few of the questions that were asked here at a bit more length. The first group of questions I want to tackle are those concerning H.323 and SIP: How important is H.323 for video telephony vs. SIP? Which one should I use? Using SIP and H.323 is a

In the past couple of months we’ve hosted several webinars with TMCnet. This last one before the summer break was about the hidden challenges of developing HD visual communication products – a topic that is dear to me. As it so happens, I presented this webinar alongside Sagee Ben-Zedeff, the writer of my sister blog here, Video Over Enterprise. The premise of this webinar was that once people start developing an HD video communication terminal, they will focus on their

Last week, we hosted another webinar with TMCnet. This time about SIP servers on embedded systems: Powering SoHo communications. It seems that everything is moving to the clouds lately, and part of this migration is also happening in the PBX realm. That said, there is a wide range of servers that need to go into the small enterprise premises, as well as PBX implementations that doesn’t rely on the cloud. One of the poll questions that were addressed to the

Our latest webinar on TMCnet was called Voice and Video over IP Communications: Assessing and Improving User Experience. As we already know that video calling is happening and we know how it fits into the UC world, we decided to discuss on this webinar the different issues related to the quality of video calling. The focus was around video, although we did deal with audio as well. For video, there are two main approaches for assessing and improving the quality

We just hosted a webinar on TMCnet regarding Unified Communication HD Visual Communications for the Masses. A long title for a pretty simple concept: we have video communications today available. How can they be used? And what are the challenges of developing such solutions? These are the kind of issues we see vendors today dealing with. It is also why we started the designing hardware for HD post series. For me, the interesting part in this webinar was the question that was asked to the audience: do you participate in video calls? While almost a third of the participants are not using video communications, the rest do. Almost a third of our audience is active creators of such video communication sessions, while others are more passive. It would be interesting to see how this will change with the introduction of video calling solutions in the consumer market. You can view this visual communications webinar online if you want. I have also embedded here the slides for your enjoyment:

We’ve just officially announced our BEE client framework solutions, a broad family of multi-protocol, multi-platform VoIP products. While we have advocated in the past for multi-protocol clients, I think we’ve taken it a step further. Not only do we offer multi-protocol support, we now offer it over multiple platforms in quite a unique manner. Last week, I had 2 meetings back-to-back, in the middle of the night (at least here in Israel, as both were with the west coast) about

My dear friend, colleague and office ‘roommate’ Sagi Subocki is our Product Manager for everything SIP and IMS for developers. Last week, Anatoli Levine and Sagi hosted a webinar about LTE and the future of IMS. There was lots of interest in this webinar, with a high registration and participation rate. I guess the topic of LTE coupled with IMS is something that is getting high demand, and it makes sense – especially when you look at the VoLTE initiative

It’s funny how things go sometimes. Just yesterday I’ve crowned my day as the day of LTE – not because of any special reason, but simply because I bumped into too many LTE related posts in the blogosphere. Here are the interesting ones: It all started in the morning, when Andy Abramson coined LTE as Long Term Excuses. It brought me to Dean Bubley’s blog – a new blog I now added to my reading list. There

Today, we’re going to host a webinar that talks about SIP Beyond Telecom. Along with my long time colleague and friend, Sasha Ruditsky, who also happens to be our CTO, I am going to discuss where and why SIP can be found in non-telecom environments. Here’s the official abstract of this webinar: The Session Initiation Protocol (SIP) was originally defined as a protocol for creating and managing sessions. Its main use is for telecommunication applications but given its extensibility and
