Call Quality, System Reliability, & Network Security

Quality You Can Trust


When you get a telephone system from VirtualPBX, you not only get our award-winning business service and features, you also get a secure telecommunication network, with VoIP call quality that is unsurpassed. We’ve taken every precaution to give you the most reliable virtual phone service in the market.


  • Hardened, co-located facility

Our carrier-class switches are stored in a co-located datacenter that is part of a government-protected network for technology and communication, and is subject to government regulation and oversight in addition to our own security measures.

  • Multiple power and telecom sources

While we don’t provide the details about our facility for security reasons, we have multiple sources of electrical as well as multiple inbound and outbound carriers. So even if the power grid or one of our telecommunication providers collapse, our system stays secure and keeps functioning.

  • Fully Redundant Systems with Backups

Beside redundancy in power and telecom sources, every component in our network and database infrastructure is redundant and backed up. Multiple components can fail without affecting customer calls.

  • Carrier Class Switching

Security and reliability are key to providing a solid virtual phone service. VirtualPBX uses carrier-class switches running our own software. This gives VirtualPBX the ability to make our own changes, and provide more uptime than any competitor.



  • All network points are firewall protected

We secure our network as thoroughly as our datacenter. No back doors, no loopholes, and no system processes that work around the network – everything is subject to our full security measures.

  • Separate Systems

VirtualPBX’s policy is that the customer calls comes first, followed by the web interface that controls the phone system. Because of this, VirtualPBX split all networks and components such that if one portion of the local or toll-free network fails, it will not affect the other. A web failure will not affect calls.

  • VoIP calls go through a secure backbone

If calls are being placed to VoIP phones or soft phones, it is vulnerable to access through the internet, something copper wire calls are immune to. Being aware of this, we have secured our hosted VoIP calls with the same measures we use for every piece of data we transfer.
