Zultys MX IP Phone Solutions

Zultys systems deliver the most sophisticated engineering in the market to provide the most powerful VoIP business solutions available for businesses from 1 to 10,000 phones and from 1 to 128 of sites around the world.

While other manufacturers (Cisco, Avaya, Mitel, ShoreTel etc.,) have chosen to continue with proprietary endpoints and protocols, Zultys embraces open standards (not open source) to deliver unmatched long term value and flexibility. Zultys platforms are ALL IN 1 appliances that deliver integrated Unified Communications, Desktop Video, Fax Server, Integrated MX Conference Bridge, Session Border Controller, Call Recording, Advanced Call Center, Cellular Applications, IVR, and entire suite of advanced user features, all on box. This powerful ALL IN 1 design allows us to cluster devices for scalability and to provide full N+1 for redundancy easier and more cost effectively than any other platforms on the market today. The Zultys platform provides unmatched remote user connectivity via on board Session Border Controller so there is NO need for VPN for remote users! At 73 watts to power the Zultys system it is up to 6 times more power efficient that its competitors.

Elegance & Simplicity

ZULTYS, Inc. is a leading manufacturer of secure, enterprise class, IP PBX telephone systems that allows you to do a LOT more with less. Being one of the most feature rich platform in the industry, we bring about a dependable IP PBX Phone switch, that is easy to deploy, use, manage and scale. It is pre-loaded with attributes out of the box, such as Soft phone, Find me Follow me, Presence, Unified Messaging, Visual Voice Mail, Secure Chat/IM, Tele-worker support with NO VPNs needed, Fax Server, Mobile client, conferencing, Twinning, Inbound call center, IVRVideo and more. Since 2001 we have been built on OPEN STANDARDS (not open source) and are natively supporting SIP desktop and cordless phones, as well as the ability to interface with SIP Trunks (with no licensing or external gateways and other point of failures), as well a T1/E1/PRI, analog trunks and more, and all this in 1 highly available 1 appliance. Our thin (30MB) desktop software makes it possible to run these applications on a MAC, Linux or PC (64 or 32 bit), on a Terminal Server or Citrix , all WITHOUT requiring expensive and cumbersome external servers like most of our competitors do. In essence, we do much more out of our 2U secure Rack Mountable appliance, than most of our competitors can do with an entire rack of servers, all at a compelling price point that easily scales to 128 locations and 10,000 users, with superb redundancy and a 99.999% high availability thanks to our patented distributed processing method, and automatic and quick failover across Lans or Wans. Since we do more with less and simplify your exposure to complexity, we call it THE ELEGANCE OF SIMPLICITY.


Located in Sunnyvale, Zultys started in 2001, much earlier on than many of today’s VoIP Providers, and while some started with VOICE and later on added data, and others started with data and later on added Voice, Zultys started with BOTH. Our facility incorporates nothing short than a state of the art Network Room for testing, an advanced Acoustic Lab and a Test Lab designed to replicate our client’s environments Our resellers have direct access to our own Engineers and our own developers. We do not outsource our technical support, and help is available at no charge for our worldwide authorized resellers. Zultys is small enough to offer personal service, and large enough to offer world class capabilities and support

Interoperability with 3rd Party

We have Engineered our MX platform with standards for convergence and with ability to connect to third party vendors, and are adding alliances weekly. From ITSPs to SIP Software Vendors that add feature, functionality, and extends the product’s usefulness and integration with other software and hardware.

Green Statement

Even our LOGO is Green ! Our MX is incredibly power efficient. The AC power requirements for the basic MX250 system and various combinations of plug-in modules are shown in the Table below. Add up the values according to the configuration. The ac power requirements apply whenever the mains power is on. A maximally loaded system configured with two hard disks and three FXS plug-ins with 26 FXS circuits off-hook requires approximately 82 W. Since we also do not require external Servers, we are more efficient than ONE 100W Light bulb, yet it can power 250 Users.


Even though our products include Enterprise class features, our fully configured appliances start as low as a few thousand dollars, making them extremely affordable and well positioned for businesses of any size.

Standards Based

Zultys has been using SIP Standards since day 1. From our trunking, to our platform to our phones, SIP is our model and to date, every major telephony vendor has made the decision to GO to SIP or is already there. We have been there for 9 years and since we have been doing it for nearly a decade, feel that we are well ahead of the competition in the product development cycle. This has also allowed us to interoperate with 3rd party appliances, software and hardware. We are an OPEN STANDARDS platform, not open source.

High Availability features

  • CO Failover: If the MX250 fails, we fail your first 2 lines to the 2 built-in FX/S Ports.
  • Drive Failover: Should 1 drive fail, the optional redundant RAID drive takes over automatically
  • Fan Failover: The MX250 has 2 fans in box. Should 1fan fail the other is enough to cool the system
  • Clock Failover: Internal battery for real time clock
  • LAN Failover: Dual LAN Ports built-in
  • Unit Failover: Clusters for redundancy in the rack and outside the rack

A World Class distribution and channel

Our products are now available, sold, distributed and supported with a world class level of Resellers, distributors and branch offices located throughout the Globe.

Thin, Integrated and Multi-Platform CTI:

Our Software works with MAC OSX, Windows 7 (already tested and certified by Zultys), Vista 64, Vista 32, XP and Linux workstations. Unlike our competitors, we do not need to run 3 or 4 unassociated software programs to perform the functionality that is integrated. 1 thin multiplatform CTI (called Media Exchange Interface for End Users or MXIE) is all you need to run all of our features.

Secure, Converged Voice, Data Platform:

Finally, our secure ruggedized Linux platform includes an optional Software Firewall that can block ports and defend against most malware attacks. You cannot ssh into our box, FTP into it, or conduct a denial of service attack. Unlike our competition, we do not use WINDOWS at the core of our product, (No Patch Tuesdays). One MX appliance is all you need to converge Voice, Data, and Video. Session Border Control (Port Mapping) is even STANDARD now on our platform, allowing you to place our MX Platform BEHIND corporate firewalls, while still enabling Tele-workers worldwide, WITHOUT the use of complicated and expensive VPNs.
