Case Study - Precision Husky

Precision Husky transformed their legacy phone system to a rock solid VOIP solution powered with Mushroom's VOIP Armor


Heavy machinery & equipment


Legacy phone system was too costly. Over $2,000/month phone bill 

•Prior to Mushroom, VOIP systems tried have failed because of network problems


Truffle with VOIP Armor was deployed to address the issues


Solved reliability and up-time issues in a cost effective manner for rock solid VOIP

All other Internet applications also benefited from better performance and reliability

•LTE wireless failover provided uptime even during disasters

Replaced expensive and unreliable single ISP links

Precision Husky is heavy machinery and equipment manufacturer serving the forestry industry since 1964. Precision Husky operates our of their 165,000 square foot facility in Moody, Alabama. Precision Husky’s VP of Engineering, Billy Daniels decided to reduce their $2,000 a month phone bill by switching over to a VOIP based phone system. However, the first few tries with such systems were challenged by network problems that caused VOIP issues. At that point Billy found out about Mushroom’s VOIP Armor solution and deployed the system alongside with  Fonality based VOIP system. Since then, phones have been up and running even during disasters where an Internet pipeline was cut and at a different occasion a lightening strike damaging part of the network – Mushroom rock solid VOIP Armor solution kept phones alive. 

Reducing the high monthly phone bill, yet not compromising on quality and reliability of phone calls

Precision Husky’s 30+ computers dependent on reliable Internet connectivity for the services they use for ordering parts, accounting, engineering services and tools. Similarly, their 5 servers heavily relied on connectivity to the Internet. Precision Husky had a legacy PBX phone system that cost them $40,000 and $250 per phone. The 30+ phones were costing $24,000 a year in phone bills alone and Billy, the VP of Engineering at Precision Husky was determined to plug this money leak. He understood that the solution lied in a VOIP (Voice over IP) solution, but had also experienced first hand the shortcomings of VOIP systems if the network is not glitch free.

Later Billy will learn that he had some other challenges coming his way. One coming from an accidental wire cut by a sewer repair nearby, which would take down all the wired Internet access in the neighborhood. Another disaster will strike, literally as a lightening, burning down some of the circuitry in Precision Husky’s local network. Luckily, Billy had designed his network to withstand all those disaster scenarios.


After experimenting with some VOIP solutions, Billy decided to add Mushroom’s VOIP Armor tunnel and Truffle appliance to its network – both to bring reliability and redundancy to his network, as well as finally pull to trigger to fully move to a VOIP based phones system.

On paper, VOIP solutions provided huge benefits and features. “The VOIP system provided 60% savings right from the get go. After my experience with Mushroom, I can simply say that every VOIP user needs 100% a Mushroom box – period”, added Billy, VP of Engineering at Precision Husky.

Billy has 2 wired WAN connection on his Truffle and 2 LTE cellular modems. The VOIP Armor tunnel is configured to seamlessly switch WAN paths as a function of the quality of the lines, so all calls have been crystal clear and none of the usual VOIP problems existing at Precision Husky any more.

Mushroom’s VOIP Armor solution enabled a rock solid VOIP system for Precision Husky. Cost savings were over 60% of the monthly phone bill and the investment on the Mushroom equipment was recovered in less than a few months.

VOIP Armor was so reliable that the phone system didn’t take a hit even during a lightening struck out one of the WAN ports and the modem. Internet and the VOIP system was 100% shielded from the outage. Similarly during an Internet pipe was cut by accident by sewage repair workers, all wired Internet lines went down, however, the 2 LTE modems connected to the Truffle automatically took over the phone calls (including the ones that were ongoing), so calls continued without any hiccups.

Since Mushroom’s overlay tunnel can present an elastic static IP address to the outside world, including the hosted IP-PBX phone system, outages on the local WAN connections didn’t even impact the IP address the traffic was going in and out, and therefore all configurations of cloud services (which VOIP was one of them) that required static IP addresses stayed up and functional.

Precision Husky transformed their costly legacy PBX phones system into a rock solid VOIP solution that was based on a hosted IP-PBX (fonality). The major shortcoming of VOIP systems being the connectivity to the Internet was Billy’s biggest challenge and he was able to solve that problem and further add cost savings to his network by installing Mushroom’s VOIP Armor solution. As Billy claims: “…every VOIP user needs 100% a Mushroom box – period.”

The VOIP system provided 60% savings right from the get go. After my experience with Mushroom, I can simply say that every VOIP user needs 100% a Mushroom box – period.”,
