Migrating to Skype for Business Cloud PBX: Play by Play Analysis

A Microsoft, Ovum and AudioCodes Joint Webinar

Microsoft Ovum AudioCodes Webinar

I have been accused of being a crazy sports fan. And I’m guilty. We may be in the midst of the Major League Baseball season, but American football is just around the corner. So when we discussed with our friends at Microsoft and Ovum doing a webinar on the adoption of Skype for Business Cloud PBX in an ESPN Sports Center-like setting, I was really excited!

Skype for Business adoption has been amazing, and we at AudioCodes, have been right in the thick of it with our One Voice for Skype for Business solution which includes among other things, CloudBond 365, Skype for Business Cloud Connector Edition appliance and our 400 series IP Phones. We understand that it is going to take a sustained drive approach to ensure success, to borrow one football term, as there are migration issues at work here, particularly to the cloud. There will also be a need to change plans when the unexpected happens, as with a Quarterback’s audible play calling at the line of scrimmage to borrow another.

Likened to football plays, we aim to analyze Skype for Business adoption together with experts from Microsoft, AudioCodes and Ovum Research in what promises to be a unique-style webinar on the subject on June 14, 2016 at 11:00 am EDT.

VoIP Quality Jitter Delay and Packet Loss

Is VoIP Jitter, Delay and Packet Loss the Best Measure of Voice Quality?

VoIP Quality Jitter Delay and Packet Loss

“One of the values that I think men in particular have to pass on is the value of empathy. Not sympathy, empathy. And what that means is standing in somebody else’s shoes, being able to look through their eyes.” Barack Obama

Empathy – being able to feel sorry for someone else’s troubles – is a basic ingredient for good mental health. However, sometimes, when irony is involved, empathy might turn to ambivalence. For example, you will naturally feel empathy when you see or hear about a building going up in flames, but you might even crack a smile if the building in question is the fire department. (Of course that would happen only if no one was injured, right?)

We recently had voice quality issues in our corporate telephony system. Now that might happen in any organization, but when it happens in AudioCodes, the company which has become the hallmark of HD VoIP, that’s ironic.

Our IT guys brought their usual armour to battle and started taking on the packet loss with Wireshark (network protocol analyser), upgrading this and downgrading that. Then they started looking at the AudioCodes products on the VoIP network; scrutinizing the latest IP phone firmware, restarting the SBCs, disconnecting the MGW.  And still, they couldn’t find anything to help pinpoint the problem.

After a week or so, one of my colleagues placed a call and couldn’t stand the noise on the line.  Naturally, he cut short the call as cellular SP has “trained” us to do over the past two decades. And since he is the Product Manager for AudioCodes Management Solutions, he decided to try troubleshooting the problem on his own (15 years in R&D can come handy sometimes), using the AudioCodes Session Experience Manager.

Now I have to apologize up front since at this stage the story gets a little corny.  He found that a substantial amount of the off-net calls originated by the UC system were faulty with a poor quality score.  After conducting a short analysis with our IT department, he found a misconfiguration of the VMware machine running one of the IPPBX servers.  He wondered why our own IT guys weren’t using the AudioCodes Session Experience Manager. Could it be as a famous man once said, “familiarity breeds contempt”?

I am not relating this story to point shortcomings on the part of our IT department (God forbid!) or alternatively to glorify an AudioCodes product.  A vendor who speaks about his own products is almost as bad as a mother who talks about her own children.  My point, rather, is to elaborate on the concept of VoIP quality monitoring.

It is human nature to reach a conclusion by reviewing the consequences of actions. The human brain is constantly on an endless quest to solve riddles and reach conclusions (Gestalt psychology or Gestaltism).  Therefore, it’s perfectly normal for an IT engineer to analyse the VoIP network, search for the causes of poor quality such as packet loss, jitter and delay and based on the analysis, evaluate the call quality.

From my perspective, this analysis method is problematic.  It’s like commenting on the taste of a casserole by evaluating its ingredients – before even cooking the dish. Voice quality can’t be accurately evaluated by reviewing only the relevant network impairments (jitter, delay and packet loss). An accurate measure of voice quality needs to be taken at the VoIP edges (MGWs, SBCs, IP phones, soft clients) while taking into account the vocoder, jitter buffer type and depth (static, adaptive), packet loss metric (Network Packet Loss Rate, Jitter Buffer Discard Rate) and more. This information can’t be obtained by only analysing the traffic.


There is a mistaken belief in the industry that VoIP Quality Monitoring applications are like insurance policies -you buy them hoping not to use them. This belief is due to decades of trusted legacy telephony and basic trust in the organizational network, devices and solutions. In Reality, VoIP Quality Monitoring should be considered for ongoing use for the following:

  • Day-to-day, end-to-end quality monitoring and assurance operations with the ability to perform proactive actions to prevent quality issues
  • Root cause analysis for diagnostics when VQ issues arise

So if you are having VoIP quality issues, I empathize, even though after reading this, you might smile at the irony.

Yaniv Christmas tree Germany

How IT Managers Can Better Manage Skype for Business IP Phones

It was a freezing, snowy night, just a few days before Christmas.

I was on one of my road trips in Germany looking at the biggest Christmas tree in the world, while trying to warm my soul with a good, local Gluh Wein. Then my mobile phone disturbed the tranquility of the moment. One of my IT manager customers was calling. I had to answer.

Yaniv Christmas tree Germany

The customer started to describe his day to day challenges and concerns. His enterprise was beginning to migrate from an IPPBX to Skype for Business and Unified communications and his end user satisfaction was poor.  His multi-site roll-out plan took him much more time and consumed more effort than expected. And he was yet to go beyond deploying at Headquarters

where he couldn’t understand what was causing some of the IP Phones to reboot several times a day. He was unable to control the end users’ IP Phones in an efficient way and solve their issues and concerns.

I reminded him about AudioCodes’ IP Phone Manager that he had been considering and I updated him about our free of charge Express Edition. I explained how in our vision, we empower IT with a full life-cycle IP Phone operation management platform and that we view the IP Phone as an IT managed device, essentially turning the IP Phone into an IT Phone.

Feeling warmer by the minute (the Gluh Wein was no doubt having its effect…) I pointed out our multi-tenant IP Phone Manager’s day to day management and maintenance capabilities with a monitoring dashboard showing the phone operation status, active registered IP Phones, non-registered IP Phones and the disconnected devices, allowing IT to proactively detect issues before they are noticed by the end user.  I also described the smart device and user search. He just needed to search on the user name and the IP Phone provided all the necessary information (IP address, subnet, VLAN, software version and more) with just one click.

In that call I convinced my customer to give our IP Phone Manager a try and let the system become the eyes into his network in order to figure out the problems he was facing. And so he did. In just a few hours after he installed the IP Phone manager, he was already able to put his finger on the problem and track the root cause. He immediately saw that when a bulk of users were disconnected it was always in the same network switch and it seemed his POE unit was not functioning well either. He replaced the switch and the issue was resolved.

Several months after installing the IP Phone Manger he wanted to migrate additional branches to Skype for Business. I reminded him that his IP Phone Manager has zero touch installation and provisioning and that he can pre-define his configuration for an automatic zero touch rollout. Once the IP phone is plugged in, it gets the proper configuration automatically.

Together, we invested a half hour in defining his open space area, lobby area and the different company branches with the proper time offset and IP Phone menu language.

A week later he called me and expressed his amazement from the simplicity of the roll out. His ability to proactively detect and solve his end users concerns easily and efficiently was well appreciated in his organization.

And it all started with a phone call while sipping some Gluh Wein……..
