How Does CoreNexa 7.0 differ from other Video Collaboration Solutions?

Lightboard Mode

CoreNexa Hosted PBX video Lightboard mode screenshot

Lightboard, also known as the “Weatherperson” feature allows a user to become part of their PowerPoint or Google Slides presentation. Similar to how Meteorologists can populate and point to maps and weather-related information that are super-imposed on their screens, this feature uses the same technology. Very useful for teachers, trainers, and sales professionals.


The Bookmark features allows users to save frequently accessed applications such as email, calendars, CRM data, etc. directly into your meetings so there is no need to move outside the meeting to access these applications or webpages.

Simultaneous Screen Sharing

The simultaneous screen share features allows multiple people within a meeting to share their screens at the same time. No more “passing the control” to share screens.

Private Sidebar with Audio, Video & File Share

The private sidebar feature provides two users with the ability to hold a side conversation, share files, etc. during a live meeting, while still receiving the audio and video from the initial meeting.

Lock & Knock

The ‘Lock & Knock’ feature provides privacy controls for meetings and huddle rooms.  Users can ‘lock’ their meetings so participants or coworkers have to ‘knock’ to gain entry.

Multiple Cameras & Flexible Video Tiles

CoreNexa 7.0 Video Collaboration video tiles

Create a powerful video experience using multiple HD web cameras during a meeting.  Rearrange video tiles for a customized screen layout.


There is no need to leave the meeting to schedule another meeting, make outbound calls, chat, check voicemails & more.  Most tasks can be accomplished directly from the CoreNexa client.

Huddle Rooms, ‘Communities’, Webinars, Conferences

A true collaboration tool, create user groups, virtual rooms, and communities for ultimate collaboration options with the Rooms package.

Cloud or Hybrid Deployments & BYO-PBX

CoreNexa 7.0 is a cloud-based video collaboration tool and Hosted phone system; however, CoreNexa 7.0 Video can be integrated into any phone system and/or physical conference rooms.

Is there a difference between a Cloud, Hosted, or Virtual phone system?

No, and yes, Cloud, Hosted, & Virtual phone systems share the same concept; however all Carriers offer different solutions and pricing models.  P.S.- We are confident ours is the best. =)

The industry coined the term ‘Hosted PBX’ since your VoIP provider “hosted” your phone system on your behalf in data centers.  Today, the terminology has shifted to ‘Cloud Phone System’ or ‘Virtual Phone System’ since all of your PBX features, applications, and calling services are located “in the cloud.”

I've read mixed reviews about cloud phone systems and VoIP phone service. How can you guarantee that I won't experience dropped calls, static and outages?
One survey targeting decision-makers involved in the selection of VoIP providers showed that problems are very rare- with only one respondent out of 208 reporting dissatisfaction with call quality. (source)

Since VoIP calls are run over the public internet, cloud phone systems and VoIP phone service are reliant on network stability and quality bandwidth.   Performing a network assessment prior to installing a cloud phone system or SIP Trunking solution is the best way to avoid potential call quality issues.

Steps you can take to beef up your network to prepare for VoIP services:

  • Run Cat5e or higher cables
  • Choose a fiber-based Internet Provider if available and/or increase your bandwidth speeds (if applicable)
  • Install a Firewall and verify all computers are free of viruses, malware & trojans
  • Add a Quality of Service (QoS) router to prioritize voice traffic
  • Add a Session Border Control (SBC) device for added security
  • Separate voice and data
  • Install a SD-WAN or MPLS solution (recommended for large companies)
What happens if I lose my Internet connection?

All cloud-based applications rely on internet connectivity; however, our Cloud PBX solution provides inherent and automatic disaster recovery so when you lose your broadband connection, your communications infrastructure remains available. In other words, your internet connection is no longer a single point of failure. When your business phone system resides in the cloud, you’re provided with a variety of call routing options.

For example, our Virtual PBX includes features like automatic failover and geo-redundancy, voicemail to email, voicemail to text transcription, and all calls have the ability to be automatically forwarded and routed to virtually any person, device or location. Plus, we can architect a redundant broadband solution with multiple seamless internet connections, cutting your costs.

Do I need a new or alternate Internet connection?
You do not need a second internet connection for business resiliency; however, a second internet connection, MPLS or SD-WAN is recommended, as it provides a great way to further solidify your network solution.
Is your VoIP platform secure against Call Hacking?

Yes, our cloud phone system technology has additional protocols in place to protect your VoIP account from PBX Fraud with real-time monitoring & alerts. Additional safeguards include password-protected international calling and the ability to disable international calling completely.

Which Carrier does the platform utilize?

According to some of our clients, one of the benefits of our cloud telephone system platform is that they never have to deal with a traditional, long distance carrier again. We manage all carrier connectivity in the cloud, with ‘cross-connects’ directly to the PSTN.  Our platform includes connectivity to multiple carriers for redundancy purposes, so no single carrier issue will impact your business.  Our carriers are chosen and maintain favor with us based on their reliability and costs.

Do you recommend performing a Network Assessment prior to installation?
We recommend performing a network assessment prior to VoIP installation. ACC Telecom’s Advanced Network Assessment Tool focuses on TCP and UDP network topology to provide accurate and objective testing of voice quality on modern telephony networks such as IP.  And since no two companies are the same, ACC Telecom’s VoIP Network Assessment is custom-tailored to fit your anticipated applications and usage.

Our dedicated RiPi3 hardware and software collect data securely to analyze simulated voice traffic over your data network to measure key attributes that affect VoIP call quality including TCP bi-directional, UDP calling tests, UDP capacity, concurrent, simulated phone calls, network stability, delay, jitter, packet loss, Carrier HOPS, PING, End Mapping, and Traceroutes.

Following the assessment, you will be presented with a report detailing the collected data with any suggestions to improve your network performance. A post-test assessment will also be performed following your VoIP installation.

Is your Cloud PBX System as feature rich as traditional PBX systems?

Yes, our Cloud Phone System includes features most organizations could not afford with their existing phone system such as call recording, video & web conferencing, and main number business SMS capabilities.

You now have the ability to manage these great features via our easy to use web management portal, with no expertise needed. You’ll be able to access carrier-class scalability, and CRM/API integration such as, Outlook, and many more, providing you with a unified solution for all of your communication needs.

How does VoIP phone system costs differ from traditional phone systems?

Data shows that businesses can save between 30-75% when moving to VoIP services. Our Hosted (Cloud-based) Phone System does not require large upfront investments like traditional phone systems.

Switching to VoIP technology will reduce your operating costs upfront and over time by eliminating costs such as per-user licensing fees, on-going maintenance, software package, and simple Admin changes.  This means your expenses are actually reduced!

Our platform is continually updated to provide your business with new, enhanced capabilities and features- ensuring your business is always on the cutting edge of Virtual PBX technology!

Not All Cloud Phone Systems Are Created Equally

The telecom market is saturated with Hosted PBX providers trying to win your business.  When comparing vendors, make sure their backbone is geo-redundant and offers automatic call forwarding options during power or internet outages.  Also, take time to look at a company’s telephone offerings. “Free” phones are typically very low-grade models that do not fit the needs of most businesses.  Lastly, be sure to choose a company that will travel to your site to install and support your new system.  Since cloud based phone systems rely on network stability, a lot of factors are involved in prepping your system for Voice over IP services.  We recommend performing a network assessment prior to implementing a VoIP solution.
