The Power of Stereo (vs. Mono) Call Recording

Posted by Kevin Levi on Mar 8, 2018 10:14:11 AM

Stereo call recording (aka dual channel call recording) offers many advantages over mono call recording, primarily in the quality of the voice recording upon playback. Simply put, with stereo call recording, the two call participants (likely your agent and a customer) are recorded on separate channels. This means that upon playback, you will hear one voice on one side of the speaker and the other voice on the other side. Similar to stereo music, the dual channel playback dramatically enhances the sound and quality. The result is a higher fidelity call recording.

Imagine a call in which the agent and the customer are speaking over one another, perhaps during a dispute. Upon playback, you need to be able to separate the two voices to understand who said what. This could be particularly important if a discrepancy arises or if a potential HIPAA or PCI compliance infraction may have occurred. You need to be able to prove who said what, and when.Dual channel.png

Recording in stereo vs. mono also helps increase the accuracy of automatic call transcribing, which is popular in many of today's speech analytics solutions.  In fact, stereo call recording improves speech to text, key word and phrase spotting, speech analytics, and voice biometrics. The phonetic quality and accuracy that comes with stereo call recording can make the difference between accurate and false analytics results.

"When you take that (stereo) audio recording and pass it to VoiceBase (speech analytics), you can then instruct VoiceBase to process those two channels separately so that you get perfect 'who said what' information," said Bryon Mathias-Fuqua of VoiceBase. "You can imagine that if a caller says a competitor's name first, it means something a whole lot different than if an agent says a competitor's name first. There are huge benefits to using Stereo (dual channel) recordings versus Mono recordings for transcription, keyword spotting, agent monitoring/script adherence and training predictive models."

High fidelity playback in stereo also allows your call center managers, quality supervisors and even business users to focus on just the customer or just the agent when analyzing calls. This saves time when trying to identify skills weaknesses or customer discontent.

Not all call recording software offers both stereo call recording and mono call recording. When selecting or upgrading your call recording system, be sure to inquire about stereo call recording.

How Call Recording Helps you Perform CPR 

Posted by Kevin Levi on Feb 19, 2018 12:05:51 PM

Three primary areas in which call recording helps businesses include (C) Compliance, (P) Performance and (R) Risk. Everything else recording does really falls in one of these three areas. With the right call recording solution in place, your contact center can engage in both proactive (preventing future issues) and reactive (remedying issues) CPR.

CPR.pngCompliance - recording customer calls and agent screens to ensure internal and external compliance. Are agents following company protocols for handling customer complaints, for example? Are they saying and doing the right things in compliance with HIPAA, PCI-DSS, Telemarketing Sales Rule, Truth in Lending Act, MiFID II, GDPR, etc? If not, they could be putting your organization in jeopardy of receiving fines or penalties, not to mention litigation and liability. Sample use cases include:


  • Replaying a sampling of customer calls in which credit card data was provided to ensure those portions of the interaction were masked or muted.
  • Listening to a recording of a call in which the FTC is claiming your agent violated the Truth in Lending Act by saying something they weren't allowed to say.


  • Replaying a past interaction with the agent to go over any established ethics violations which occurred and discuss how to remedy them during future interactions.
  • Replaying recordings for staff to demonstrate compliance best practices by high-performing agents. 

Learn all about compliance recording

Performance - assessing past customer interactions (audio recording and agent screen recording) to uncover weaknesses in delivering service and identify areas for skills improvement.  These captured calls can also serve a number of other purposes for the contact center, such as:


  • Generating customizable performance reports to assess agent performance.
  • Identifying root causes of issues so immediate action can be taken to remedy the problem.


  • Understanding how effectively your processes and technologies support customers so enhancements can be made.
  • Identifying areas to improve operational performance and customer interaction workflow and improve business processes.

RiskLeveraging recorded calls to settle he-said/she-said customer disputes, prove compliance, understand why a customer defected and how to prevent it from happening in the future, and more. Recorded interactions do more than give you a glimpse into what happened during a call - they provide the full interaction exactly as it happened. With this data, you can mitigate risk on many fronts by providing the recording as evidence of precisely what occurred (and what did not occur). 

Use cases include:


  • Replaying a past interaction for a customer to disprove their claim that your agent stated that a full refund would be offered.
  • Using a recorded call to show regulatory bodies how proper protocols were in fact followed.


  • Sharing best-practice calls with all agents to demonstrate proper interaction performance so they can echo those best practices moving forward.
  • Sharing poor-performing customer interactions with staff to demonstrate how not to fall into any risk-related traps.

These are just some of that many, many ways in which call recording software can empower a business.

3 ways to use your call recordings to increase productivity

Posted by Kevin Levi on Feb 14, 2018 10:44:42 AM

by Dr John Yardley, Managing Director of JPY Ltd, London, England


These days, business call recording is still seen as a grudge purchase. An insurance. Something to fall back on when things go belly-up and you need to know who actually said what. But call recording can also be used on a daily basis to greatly improve your company’s productivity. Here are our 3 tips to achieve this:

1. Make your calls easy to find

Although the process of recording calls has become mainstream, the process of finding those calls can be difficult or costly. Recording your calls is no good if it takes you an age to find the call you want or you have to involve the IT department in the process. And although simply listening again to calls can be a major benefit, being able to search them for keywords, can give you a step improvement in productivity. Just think how useful it is being able to search your emails? By transcribing your recorded calls using automatic speech recognition (ASR) you can search them just as you would your email.

2. Make you calls shareable

You may have already heard about the benefits of email transparency, well call transparency can prove just as valuable. Recording calls is not just about taking people to court, but rather to share conversations internally - and that includes sharing them with yourself - and avoid the miscommunication that often happens when you are relying on your memory or scribbled notes. Whilst many organisations invest in expensive CRM solutions, they only tell a part of the story. By intelligently sharing your call recordings and linking them to your CRM, you can foster a culture of transparency in your organisation and ensure that everyone is being kept in the loop - without sacrificing privacy.

3. Combine your phone calls AND your emails

Bringing together your phone calls and emails in one shared inbox brings even greater efficiencies. Seeing the entire thread of a conversation with a customer or supplier in one place avoids the need for countless updates from one team member to another trying to work out who was involved with or what the last communication was. New team members can instantly get up to speed with a project or help with that handover when someone is off sick or on holiday. Furthermore, the context information available from emails can massively improve the ability to find relevant phone calls.

About Threads

Threads is what we call an intelligent message hub and when used with Orecx, is the perfect way to utilise our tips.

Selecting the Right Recorder to Power your Speech Analytics

Posted by Kevin Levi on Feb 12, 2018 11:21:58 AM

Speech analytics can help your contact center and business garner invaluable customer intelligence which you can use to dramatically enhance service, increase sales conversion percentages, understand buying behaviors, rescue defecting customers and so much more. The applications are truly endless.

But first, however, you must consider the call recorder that will enable your speech analytics solution. There are many recording applications available, and therefore there are specific aspects you want to look for to ensure you wind up with the most accurate and actionable speech analytics data. The quality of the recording itself can have a profound effect on the quality of the speech analytics output.

Important Call Recording Components to Consider for Speech Analytics

  • Stereo recording
  • High quality codec
  • Access to multiple codecs
  • Ability to add meta data to a call
  • Metadata filtering
  • Portability of recorded call and data
  • Open API for easy interoperability

A Word on Stereo Recording

A recorder which features 'stereo recording' capability will lead to much higher quality audio upon playback. Improved quality translates into a better listening experience and also improved speech analytics.  Oreka TR records each individual on a separate channel to produce high fidelity voice recording.  High fidelity improves speech to text, key word and phrase spotting, speech analytics, and voice biometrics.  The voice recording and meta data is available to any third party speech analytics tool, including IBM Watson, Tethr and CallMiner.

When selecting a call recording solution, it is best to inquire about the company's speech analytics strategy and capabilities to ensure you'll have what you need to run high quality speech analytics.

Merits of Unlocking your Contact Center

Posted by Kevin Levi on Jan 16, 2018 3:12:37 PM

Utilizing open source technology into your contact center brings added control, cost reduction, speed and flexibility (among other advantages) over proprietary solutions. In essence, open source technology unlocks your contact center and gives you the latitude to control your own destiny, so to speak. unlock.jpg

  • Control: You are in control of the design, deployment and future development of the software. "You also have full visibility into the code base, as well as all discussions about how the community develops features and addresses bugs." (opensource.com
  • Cost: It costs far less to acquire, operate and develop enhancements.
  • Speed: Without the need to crack proprietary code or develop complicated APIs, the speed with which you can customize, test, deploy, and support the software is dramatically improved. "Because open source solutions are openly available and can be explored for free, it's often much faster to investigate options and get solutions off the ground." (opensource.com
  • Flexibility: You can utilize virtually any CRM system, databases, PBX switch, speech analytics, IVR analytics, workforce management, surveys and more. Open source is also operating system, hardware and database agnostic.
  • Security - "Open source software's code is often more secure because it is much more thoroughly reviewed and vetted by the community (and any issues that do arise tend to be patched more diligently." (opensource.com
  • Reliability - "Because there are more eyes on it, the reliability of open source code tends to be superior as well. With a worldwide community supporting a code base—rather than one team within one company—code is developed on online forums and guided by experts." (opensource.com

“When businesses turn to open source software, they free themselves from the severe vendor lock-in that can afflict users of proprietary packages. Customers of such vendors are at the mercy of the vendor's vision, requirements, dictates, prices, priorities and timetable, and that limits what they can do with the products they're paying for” (PCWorld).

Unlocking your contact center with open source, standards-based call recording software brings additional, very specific advantages. Here is a list of key features and benefits:

  • Open data model – ancillary features and processes along with enhanced meta data for pre and post call processing. This helps you generate the most value from your recordings with the richest set of data points.
  • Open API – the software can be controlled by third party applications. This extends the capabilities of the system by having the recorder serve as an engine for data aggregation and analysis.
  • Open file formats – customizable formats to match desired use case(s); data portability within and without the framework of the customer data management system(s); leverage third party applications in WFO and Speech Analytics for ‘best in class’ for customer requirement. The open nature of exported data makes it possible to share recordings with business users and others outside of the contact center.
  • Open web interface – support for all browsers, including mobile platforms, and internationalization. You can access your recordings from virtually any smart device, anywhere in the world. 
  • Modular components – removes complexity and costs associated with bundled applications. You are not saddled with (or having to pay for) capabilities you will never use.

Downloaded for free, the Oreka GPL basic call recording solution from OrecX is the only free voice recording software on the planet that can be downloaded in just 30 minutes and requires no maintenance.

'Total' or 'Selective' Call Recording Software?

Posted by Kevin Levi on Jan 12, 2018 10:57:23 AM
Total or Selective Recording.jpg

When it comes to call recording software, you have two options: 100% total call recording (capture every single call) or selective recording for quality assurance which captures only a small sampling of calls to gauge customer service levels. Which approach is best for your needs? What do you need to know to make this determination? Are there other advantages to capturing every call? What about compliance, risk management and dispute resolution?

Here are some of the differences between selective and total call recording:


Total Call Recorder Selective Call Recorder
100% capture of all calls (audio of agent and customer) Recording of only a sampling of calls (audio of agent and customer)
100% capture of all agent screen activity (optional) Recording of only a sampling of agent screen activity – to coincide with the selective audio capture
Recordings archived for months or years Recordings typically not retained long (perhaps a month or two at most)
Calls are securely stored and sometimes encrypted to ensure their integrity and to restrict access Sampling of recordings determined according to pre-set variables (only 3 calls per agent per week, e.g.)
VALUE: Recordings used to settle disputes, verify order approval from customers, and verify PCI/HIPAA Compliance, e.g. VALUE: Recordings used to assess agent performance, identify workflow issues and monitor customer satisfaction


Ideally, a contact center has both a total call recorder and selective call recording. Together, you have the tools needed to effectively monitor customer satisfaction, assess contact center agents, ensure compliance protocols are followed, and have the ability to resolve he-said/she-said disputes effectively.  This combination is becoming more and more prevalent in contact centers today as it gives managers and business users the flexibility they need to get the most value out of recorded customer interactions.

Using Call Recording to Build Buyer Personas

Posted by Kevin Levi on Jan 3, 2018 12:32:57 PM

You can use recorded customer calls to help you build your sales and marketing buyer personas

One of the hardest things for sales and marketing professionals is to identify and clearly articulate who the target buyer(s) is/are. This is about more than just their job title. Buyer personas should include a full understanding of the following characteristics of each individual buyer (at the least):

  1. Job title
  2. Roles and responsibilities
  3. Challenges
  4. Hot buttons
  5. Risk aversions

Think about the customer conversations your sales team and your call center representatives have with your potential bu

yers every day. They are speaking directly with these individuals already, and by sharing select recorded conversations, they can provide a wealth of knowledge to the sales and marketing teams to help them understand the characteristics like those listed above.


"I don't have any free time." "I'm strapped for budget already as it is."

These are just a couple examples of the types of challenges your target buyers face, and many of these will likely surface during your customer calls - whether it's during an initial sales call to introduce your company and its products/services or it is a call in which the customer called for technical or product support. Either way, your buyers' challenges will come up, and when they do, you can share those insights (or the entire conversation) with the relevant sales and marketing folks in your company to help them get into the mind of your potential customers. 

Hot Buttons

"My team doesn't have time to learn about a new product." "My team needs to be producing, not learning about some new solution."

When your sales and customer service professionals are speaking with your target buyers (or existing customers), these hot buttons will surface. The customer will react to something your company representative says with a comment indicating one of their hot buttons. For example, your salesperson mentions that the new widget you are offering can save the company thousands of dollars a month, but it takes time to learn how to use. If the would-be customer reacts negatively to having to teach his team how to use the new widget, then you can share that insight with your sales and marketing managers to help them craft future campaigns around that (and other) hot buttons. By recording every call your sales and customer service teams make will ensure you have these calls captured and shareable with the relevant staff when these types of insights arise. 

Risk Aversions

"I hate being the first to try something." "I only like products that have been proven to be effective."

Customers and prospects will occasionally share their risk aversions on the phone, like the examples above. Suppose your customer service rep is speaking with an existing customer and tries to upsell your new product, and the customer replies by saying he/she is not comfortable trying new things until they are proven. This is solid-gold customer insight that you can share with your sales and marketing teams to help them craft messaging that will resonate with future customers. 


These are just a few examples of the rich insight your recorded calls can yield in terms of better understanding your target buyers and what makes them tick. Start sharing this intelligence with your sales and marketing teams today.

Cloud Call Recording: Keeping Attackers Out

Posted by Kevin Levi on Dec 5, 2017 10:52:52 AM

Cloud call recording applications are rising in popularity, along with cloud contact centers in general. The advantages are significant, primarily around the elimination of procuring and maintaining costly hardware, the ability to access call records from just about any web-connected device and subscription-based models. With these many cloud benefits, however, comes a heightened risk to internet-based attacks which aim to compromise your recorded calls and your private network. The emergence of mobile phone recording also adds to this ongoing security challenge.XSS-Figure02.png

There are a number of risk-mitigation measures you can put in place, such as OWASP (Open Web Application Security Project) Level 2 security, but first you need to understand the types of threats that exist to your cloud call recording system.

“Most vulnerabilities found in the proprietary code of Web applications are unknown to security defense systems; these are called zero-day vulnerabilities. This is because these vulnerabilities are specific to each application and have never been known before. A skilled attacker can easily find these vulnerabilities and exploit the issue without being detected. The best defense against these attacks is to develop secure applications. Developers must be aware of how application attacks work and build software defenses right into their applications.

Educating and informing developers about application vulnerabilities is the goal of OWASP. The organization has put together a list of the most common application attacks. This list is renewed every three years, with the latest refresh in 2013.”

Download our white paper for descriptions of four of the most common web-based application attacks that you should be aware of in your contact center.

Call Recording in OpenSIPS 2.4 Using SIPREC

Posted by Kevin Levi on Nov 9, 2017 11:23:00 AM

The ability to record the calls that go through your platform is gradually shifting from being a feature to being a necessity. Whether you run a call center and you need it to monitor your agents’ activity,  to comply with your countries laws, or simply to improve your services, you need a recording solution that is simple to deploy and does not affect the quality of the calls. This article shows how you can achieve that using the new SIPREC module available starting with OpenSIPS 2.4.

The State of Call Recording: From Feature to Platform

Posted by Kevin B. Levi on Aug 8, 2017 10:51:38 AM


If you have ever called into a contact center, chances are you have heard the phrase before: “This call may be recorded for training quality assurance purposes.” We may not think much of it, and completely forget we’re being recorded once an agent answers the phone. While the customers calling in never get to hear that recording, or ever even know if the information truly does help training, the opposite is true within the Contact Center. call-recording-main.jpg

Call Recording allows your business an entirely new path to improve and optimize, with entire new sets of data and information to analyze. But, we’ve always seen Call Recording as nothing particularly special, just another great feature users can gain thanks to the power of Business VoIP, and the Cloud.

However, as it turns out, there’s so much more to call recording than we ever really thought. In fact...
