Q: Low cost unified communications service providers?

I have to answer on behalf of our company, Nexogy. If by video conference you do not refer to boardroom conference but rather user's device (tablet, smartphone, Mac or PC) we offer a service where no hardware, no contracts, no maintenance and no minimums are required and you can use the service from any device, anytime anywhere.

We provide a soft client you install on your favorite device (iPhone, android smartphone, iPad, android tablet, Mac or PC) enjoying major features of a business telephone system, but also providing video calls and private chat service... Read More

Q: What defines video communications today (Skype, Google, Apple, H.323 and SIP) and how it plays into Unified Communications?

Video communications will be defined by the best technology capable of providing the best quality and end user experience. webRTC (more onWebRTC) defines a clear scenario for peer-to-peer communications where a very specific set of interactions between clients (browsers) protocols (SIP), codecs (VP8 for video, Opus, G711 for audio) and network (ICE, STUN, TURN) all play with a simple goal in mind: the shortest distance between two points is a straight line... Read More

Q: How is cloud computing shaping enterprise communications?

This question has two answers, one that requires writing a book and the simple version that fits here:

The move of all major communication means to the cloud impacts the enterprise in many ways. Think voice and video directly from your browser to another browser (webRTC), not only it requires nothing but the existing device the end user already has (smartphone, tablet, Mac or PC) but also the power to process it and the bandwidth required, peer-topeer is king. Also, as clearly mentioned in Matt Jones'answer, the shift of the heavy and expensive PBX to the cloud, reducing the footprint to only desk IP Phones or even to the user's preferred, tablet, smartphone, Mac or PC...

Q: What is lacking in Unified Communications today?

Ubiquity. I have read that 60% of phone calls made while on your desk are done using your mobile phone, not your desk phone. There is a reason why there's still such a separation between your devices even when companies likes us offer so many options to reduce the friction: Find-Me-Follow-Me, forward conditions of all types, notifications, visual voice mail, etc... Read More

Q: What are the main pros and cons of using Video Surveillance as a Service (VSaas)? Is this technology really the future of VS?

The question has plenty of angles, but I will make it simple and straightforward. Hosted Video Surveillance is nothing more than having only cameras at the sites being monitored and all servers capturing the audio and video media are remotely located elsewhere.

My company offers Hosted Video Surveillance and customers enjoy the ease of use and simplicity of installation of our powerful cost-effective PoE cameras. Not only that, but all media for audio and video playback (retrieving recordings) resides in the cloud, in our collocations facility with fully backed-up servers and IP infrastructure.

Another big pro is the fact that customers only need to worry about replacing cameras should technology present new, enhanced and better options. All back office software is the provider's responsibility so no hardware replacement, fork-lift upgrades or server maintenance is required...

Q: How have third-party OTT mobile VoIP services impacted upon network operator services?

If by network operator services yo mean the MNOs, remember that VoIP is just another data packet and the size of those packets depend on the CoDec used (Codecs are used to convert an analog voice signal to digitally encoded version). An uncompressed VoIP CoDec like G711 can take as much as 68Kbps where G729 about 18Kbps (including header). I have thoroughly tested various types of CoDecs on different type of networks in order to determine which CoDec works best at any given access (MNO data network, wifi).

The way we set up our VoIP Mobile apps is to use G711 for the MNO data network whereas if the customer is on a wifi connection , G729 is preferred. You would frown upon why am I going to put more strain on a less controllable environment like that of at&t 4G or LTE or T-Mobile's HSPA networks and it is totally valid: an internal test we made determined that using G711 consumes as much as 1.5Mb of transfer rate per minute so if you make a one-hour call, well, you have put down 90Mb off your data plan; ouch... Read More

Q: What are the various open source SIP based softphones available?

I have tested jitsi (jitsi.org | Jitsi) which provides XMPP (supporting facebook, man, yahoo, etc) Audio and Video calls. It is very flexible and easy to use and configure... Read More
