The Prophet Jeremiah

Identifying Toll Fraud is Harder Than finding a Needle in a Haystack

What Does That Have To Do With Big Data?

[Post is better viewed on the blog Website]

The Prophet JeremiahAt the time of creation, God spoke with man directly, without any proxy. God spoke to Adam, Eve, the snake and even handled the first murder interrogation by himself when asking Cain “Where is your brother Abel?” After this, when there were too many people, God abandoned the one-on-one approach and started sending his messages and commands through prophets. Then came the kings who listened to the oracles and ignored the prophets.

And then came the scientific revolutionaries, visionaries, dreamers and most recently, the predictors. Unlike prophets, scientific revolutionaries, visionaries and the dreamers, the predictors look to the past to predict the future. And the deeper the predictor studies the past, the clearer he can envision the future.

The predictor is a by-product of an emerging technology – big data. I am sure that big data was invented by a male, since it’s totally built on a male character trait –don’t throw anything away that you may one day need.  This is probably the reason why another male invented large garages. Unlike the traditional rational data bases, big data deals with voluminous amounts of unstructured data (not organized by any method), which is gathered from many sources in large quantities, various formats and varying qualities. There are four main characteristics related to big data (aka the four Vs); Volume, Velocity, Variety, Volatility. Allow me to add a simple analogy from my life to describe the difference between rational and irrational data bases. When I return from the grocery I pile ALL the vegetables and fruit in the refrigerator inside their plastic bags. My lovely and more rational wife washes them all, skins the melons and watermelon and cuts them into pieces, peels the vegetables and sometimes cuts them as well, to be ready for making salad or cooking.

Mr. Gurdeep Singh Pall is the Corporate Vice President for Skype and Lync at Microsoft Corp. Mr. Pall just returned to the Lync unit, after spending the past two years working on Artificial Intelligence projects within Microsoft.  Pall used his opening keynote at this year’s Lync Conference to describe how the work of analytics and Bayesian predictions, will eventually make its way into communications systems. In practice, Singh Pall said, “We can actually predict who you will be calling in the next five minutes.”

Big data and Unified Communications & VoIP services

Unified Communications and VoIP services collect a lot of raw data; this data is worthy of analysis due to its wealth of intelligence. Many companies are increasingly aware that there is information that can be collected and refined to an essence which can be used for performance optimization and network design improvements. UC and VoIP big data analytics will be the key element in converting the big data to a tool which ensures cloud-based VoIP service, including privacy, security, toll fraud, performance, cost and more.

So what can you do with voice analytics?

  • VoIP analytics will build its own multi-layered picture of the network’s topology derived from the big data over time.
  • VoIP analytics will provide Network & Users Profiling
  • VoIP analytics will provide Advanced Call fraud detection and attack prediction
  • VoIP analytics will provide Advanced Multi-Dimensional Cost Analysis

Toll Fraud detection and prevention using big data analytics

Call fraud is associated with significant revenue loss and is hard to discover. I read that discovering call fraud in the masses of call records is more difficult than finding a needle in a haystack. Actually, that’s an easy problem to solve; you know how a needle looks like and by adding enough manpower to do the looking you can eventually find it.  But fraud calls are similar to legitimate calls, so if you can’t identify a fraud call, no matter how much manpower (or CPU power in this case) you put on the job it will be impossible to detect. It’s more like trying to find a specific strand of hay in a haystack.

A common approach to detect call fraud is based on examining accounts made up of several statistics that are computed over a specific period. For example, average call duration, longest call duration, and numbers of calls to particular countries might be computed over the past hour, several hours, day or several days. Account summaries can be compared to thresholds for each period, and an account whose summary exceeds a threshold can be queued and analyzed for fraud.

VoIP analytic fraud detection is designed on a statistical principle of dynamic VoIP fraud detection. The algorithm is based on Tracking Account Behavior which is able to alert or terminate the fraudulent call as it occurs. The algorithm will relay runtime & historical attributes gathered per user, group of users, sites, SIP interface and etc. The VoIP analytics create a signature of predicted usage behavior for each user/group/interface, update the statistical model with each call and score calls for fraud using predicted behavior as the baseline. When a call exceeds a predictive user signature boundary, the VoIP analytic may take actions as per the configuration.

The VoIP fraud detection analytic is built on three stages:

  1. Training – The analysis of large numbers of enterprises of various types such as: Unified Communications, Contact Center, etc. Based on this information, the VoIP analytic Fraud Detection System creates preliminary statistical information which is later segmented per the organization’s characteristics.
  2. Adaptation – Adjustment of the statistics collected in the previous stage to the specific organization. This is done by comparing in real-time the statistics to actual call activity of the organization.
  3. Test – Each call is compared against the statistical call pattern in real-time. Calls that don’t match the pattern will result in fraud alarms with the probability (confidence) grade.

 Conclusion

We are often tempted to impose the way we see things through the prism of our own life experiences on our friends and family while in actuality, what we are really doing is judging them for the way they see things.  A friend once told me that life experience is like a flashlight hanging on your back when you are going forward, in other words, useless.  That may be true. But in the case of Big Data analytics, the system’s life experience is the basis for predicting a better future.

Lync Conference 2014 Ran Inbar

Lync Conference 2014 – Smashing into a New Era

[Post is better viewed on the blog Website]

Lync Conference 2014 Ran InbarThe second annual Lync Conference is now behind us, this year held in the Aria Convention Center in Las Vegas and again a sell-out.  Themed “Coming Together”, the event was attended by some 1,800 end-customers, partners and Microsoft staffers.   Mecca for the Lync faithful, the Lync Conference is the place to be for Lync education, networking and a peek at coming attractions.

This year saw an increasing number of enterprise users, many sharing their experiences in moving beyond their early pilots to full implementations.  During AudioCodes’ private “Circle of Excellence” pre-conference event, we heard from a number of Lync network administrators about their successes and challenges in implementing Lync voice and conferencing across their enterprises.  Cargill, Amgen, Bally Entertainment and a number of other large enterprises all shared their Lync migration stories in great detail.  You can read a summary of the event by Brent Kelly, Consultant at KelCor.

We also took the opportunity to demonstrate our new 430HD and 440HD IP Phones along with our Better Together over IP functionality for Microsoft Lync.  Shown here, Ran Inbar, CTO Unified Communication for AudioCodes demonstrates the Better Together functionality to Matt Landis, a widely read blogger on the topic of Lync.

On the main keynote stage, Microsoft announced some key milestones for Lync with Derek Burney demonstrating the increasingly integrated Skype/Lync experience, the newly updated Lync client for Android tablets and a pre-release look at voice-driven “zero click” Lync client features.

Microsoft Lync Conference 2014 Gurdeep PallFollowing Derek, Gurdeep Singh Pall returned to the stage, announcing the end of the era of Unified Communications and the start of Universal Communications, bringing a consistent user experience across media types and devices. Gurdeep also demonstrated a web-based Jscript application, showing a somewhat un-realistic medical consultation experience, where a patient could hold a video call with a doctor.  (While the technology is very much realistic, in my experience, actually getting a doctor on a video call is highly un-realistic – they seem to be pretty techno-phobic.)

AudioCodes had the opportunity to share our experiences on a panel discussion on the Lync Ecosystem, sharing the stage with AT&T, Jabra, Unify2 and HP.  Challenging the “one throat to choke” argument, the panel dissected the benefits of the well established relationships between the large systems integrators, partners and enterprise buyers.

And finally, in an over-the-top spectacle, Microsoft’s exhibit featured a “product launch” cage where visitors could use a large slingshot to launch legacy telecom devices into a wall, aiming for a target with a gong in the center.  The occasional direct hit would fill the hall with the crashing sound, followed by cheers from the crowd.

Cloud based enterprise mobility suite by AudioCodes

February is a busy month for us. We are now in the midst of the Microsoft Lync Conference and Mobile World Congress 2014 is taking place next week.

Mobile World Congress is special for us this year as we are finalizing the move of our enterprise mobility suite to the cloud and enriching it with new functionality.

What is AudioCodes One Voice for Enterprise Mobility all about?

Our newly launched solution, AudioCodes One Voice for Enterprise Mobility, creates a complete integration of mobile UC with enterprise UC in a secured and managed manner. It enables business employees to communicate with their colleagues seamlessly from their smartphone devices by initiating VoIP calls over Wi-Fi and cellular data services, through almost any enterprise PBX or IP-PBX. The solution allows enterprises to improve collaboration between their employees through features such as advanced dialing, smart contacts, enhanced presence, instant messaging and one-number reach. Enterprises can also dramatically reduce their cellular communications charges when roaming or using their private network.

Also included in the newly launched solution suite is cloud-based voice dialer application. We developed an Automatic Speech Recognition (ASR) solution for the Interactive Voice Response (IVR) market. By using our voice activated name dialing technology, we allow callers to state the name of the person or department they wish to call and be automatically transferred to the requested party, thus, relieving the hassle of searching for phone numbers or waiting to speak to an operator. This is an advanced service that can easily be integrated with most of the existing PBXs and IPBXs deployed today on the market eliminating the need for replacing existing equipment.

The solution is ideal for users on the go, specifically for making business calls while driving. It will be much safer and efficient to use our voice for dialing rather than our hands (and more in-line with legal regulations in some countries).

We are getting great initial feedback from our partners and customers and we are looking forward to hearing your feedback as well. We invite you to meet with us at Mobile World Congress. We are located at Booth #9, Section #5E81 in Hall 5. Just send me an email with your preferred time for getting together.

I don't gamble

I Don’t Gamble

The AudioCodes-Microsoft Lync angle

[Post is better viewed on the blog Website]

I don’t gamble.  Not that I hate gambling, or that I don’t understand the “thrill” that comes with it.  I just don’t gamble.

When I was in my early 20’s I went on a family vacation in Puerto Rico, and our hotel had a casino.  I had 5 quarters in my pocket when I sat next to a slot machine.

4 quarters went away in a blink of an eye.  The fifth gave me back 6 quarters, and as I was about to kiss the last one goodbye and move on, I won $86.

I took the money and ran off to rent a jet ski. That was it. I never put a single coin in a slot machine since.

I recalled this since 2014 starts off for me with an unusual sequence of travel destinations:  I just got back from Macau China two weeks ago from our APAC sales kickoff event, and I’m heading next to Las Vegas for the Microsoft annual Lync Conference.  The two biggest gambling destinations in the world, 1 month apart, for someone who doesn’t gamble. Go figure.

I don't gamble

2014 is starting off on a very positive note for our Lync program.  We have introduced a new high capacity session border controller (SBC) which has sufficient capacity to cover the data centers and headquarters of 99.9% of the world’s enterprises.  We focused significant development efforts on functionality, security and interoperability in the last 3 years, and in 2013 we were able to quickly scale up the capacity of our SBC.  I think that the timing is pretty good because we are seeing enterprises scaling up their Lync deployments, and as they start retiring legacy PBX and ISDN/T1 trunks, they are moving to SIP Trunking.  This is exactly where we fit in with our SBC, as part of our very successful One Voice for Lync offering which includes gateways, SBC, SBA, IP Phones and applications for Lync.

Our release got a lot of positive industry reviews such as the article Thinking Big with AudioCodes by Blear Pleasant on UC Strategies.

“That’s why AudioCodes is “thinking big” and introduced the Mediant 9000 Session Border Controller, which supports up to 16,000 concurrent sessions and extends the capacity of AudioCodes Mediant SBC family.  As part of AudioCodes’ One Voice for Lync product portfolio, the larger capacity SBCs enable enterprise customers to consolidate the network infrastructure for Microsoft Lync, simplifying training, deployment and support. AudioCodes and Microsoft have been working together for years, and AudioCodes realized that it was important to expand its SBC capacity in order to better support large Lync deployments. This is especially important as the momentum for Microsoft Lync continues to grow, with nearly 60% of enterprises with over 500 seats surveyed by Infotrack deploying or planning to deploy Lync.”

It was very clear to us that once we complete the networking products portfolio, the next step would be to offer a uniform management suite for it, and that we did!  We just announced our One Voice Operations Center which is a holistic suite of life-cycle management applications for large scale cloud or premise-based unified communications deployments.  With that, we are very well positioned to serve the largest of the Fortune 500 enterprises as they roll out Lync globally.

Just before the Lync conference starts, we will be hosting a closed user group event of top notch Fortune enterprise customers, for a round-table discussion about Lync global roll out best practices. Later in the week we are holding a “Vegas Style” party for our partners and customers. If you are coming to the event please make sure to stop by the Audiocodes booth #625.

All in all I expect we will have a great week in Vegas.

It makes me feel that if you plan properly, you don’t have to gamble…
