Cloud-based “Hosted” VoIP Phone System


The Cloud PBX Voice Alliance connects VoIP dealers across the US to offer support and services.

 Full-Featured Hosted Phone System + Nationwide Calling

ACC NEXUS CLOUD PBX is a cloud-based phone system ideal for small to mid-sized businesses, multi-location businesses, and start-ups alike.  ACC’s cloud based phone systems are attractive because businesses pay a low monthly cost for their phone system features, applications, and calling services. ACC NEXUS CLOUD

PBX system allows companies to grow with their phone system and add new users and locations easily without a large upfront investment, and with built-in geo-redundancy and automatic disaster recovery, you can rest assure that your phone system is always working for you, not against you. 

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.

Q: 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."

Q: 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 that prioritizes voice traffic
  • Separate voice and data
  • Install an MPLS solution (recommended for large companies)
Q: 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 and 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.

Q: 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 or MPLS is recommended, as it provides a great way to further solidify your network solution.

Q: Is your VoIP platform secure against Call Hacking?

Yes, our 3CX Hosted VoIP phone system technology has additional protocols in place to protect your VoIP account from PBX Fraud with real-time accounting monitoring & alerts. Additional safeguards include password-protected international calling and the ability to disable international calling completely. 

Q: Which Carrier does the platform utilize?

The benefit of our 3CX Cloud Telephone System platform is that you'll 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.

Q: Do you recommend performing a Network Assessment prior to installation?

We absolutely 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.

Q: 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.

Q: 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. (Source) 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!
