quality

Freudenberg Sealing Technologies is a leader in customized sealingsolutions, requiring intensive customer contact. In order to increase
productivity, reduce travel and cut communications costs, Freudenberg
adopted the Microsoft Lync Server 2013 Unified Communications systemwith AudioCodes’ Lync-certified Media Gateways and Survivable Branch
Appliances.

Background
Freudenberg Sealing Technologies (FST – www.fst.com) is a global organizationthat provides customers with high-quality, custom-engineered sealing products andprocesses. Headquartered in Weinheim, Germany, FST is one of sixteen subsidiariesof the Freudenberg Group, with a presence in over 20 countries worldwide.
FST’s European operations include over 8,000 employees in 9 countries. “As acompany specializing in customized solutions, we have to spend quite a lot of time withour customers,” said Steffan Haas, Head of IT Infrastructure. “This means companyemployees spend a lot of time out of the office resulting in high travel expenses.”

Challenges
With communications and travel costs rising out of control, Freudenberg’s CFO
mandated the company’s IT team to find a solution that would keep employees intouch with their customers, while reducing the number of in-person visits.
FST contracted with the telecommunications consultant Glück & Kanja Consulting
AG (www.glueckkanja.com) to find an optimal solution that would include instantmessaging, audio and video conferencing, ad-hoc online meetings, presence services,
instant messaging, and desktop sharing. The consultants, following a careful analysis
of FST’s requirements, proposed a company-wide deployment of the Microsoft Lync
Server 2013 Unified Communications platform.
As a software-only platform, Microsoft Lync requires interoperable communications
hardware to complete its enterprise offering. FST needed additional hardware
components that would provide seamless and reliable connectivity between thenew Lync platform, existing PBXs and public telephony networks at its offices acrossEurope.

Solution
Under Glück & Kanja’s guidance, FST selected AudioCodes as the sole provider ofLync voice connectivity hardware. Explaining their decision, Michael Breither, UC
Lead at Glück & Kanja said, “Freudenberg’s selection of AudioCodes solutions was
critical to its Lync implementation strategy. As part of AudioCodes’ One Voice for
Lync program, its Mediant gateways and Survivable Branch Appliances ensured asmooth migration from FST’s legacy systems, seamless interconnectivity between
Lync and the PSTN and the potential for scaling up capacity when needed in thefuture.”
FST deployed a number of AudioCodes components to complete its Lync 2013voice deployment:• FST’s offices employ the AudioCodes Mediant 1000 and Mediant 800 Media
Gateways to provide connectivity to the PSTN and legacy PBXs. Both theMediant 1000 and 800 are certified for interoperability with Lync 2013

reducing the time required for commissioning and testing. The Mediant 1000
offers a modular, “pay-as-you-grow” architecture, supporting up to 120 analog and digital voice channels and 150 SIP
sessions. The Mediant 800 supports up to 60 analog or digital voice channels and 60 SIP sessions.
• For its branch offices, FST chose the AudioCodes Survivable Branch Appliance (SBA). The SBA is a Lync-certified media
gateway hosting Microsoft’s SBA software, ensuring continued access to Lync services – placing and receiving voice
and data calls - during WAN outages. AudioCodes offers the SBA on both the Mediant 800 and Mediant 1000 hardware
platforms.
• Freudenberg uses AudioCodes MediaPack Analog Gateways for connecting legacy telephones, fax machines, and PBXs tothe Lync servers.
• The AudioCodes Session Experience Manager (SEM) monitors the quality of voice-over-IP calls within the enterprisenetwork and over the trunks connecting it to service providers. With SEM, Freudenberg’s IT managers receive a detailed
view of voice traffic quality, allowing them to quickly identify, fix and prevent issues that can affect the VoIP calling
experience.

Freudenberg Sealing Technologies’ Lync 2013 and AudioCodes installation is currently used by over 2,000 employees. Thecompany plans to expand its Lync deployment to cover 5,000 users at 11 offices across Europe.
AudioCodes’ solution has enhanced FST’s Lync deployment by offering:• Smooth migration of legacy telephony and fax equipment to Lync
• Fully Microsoft-certified voice-enabling solutions• Reliable and scalable PSTN connectivity• Survivability for remote branch offices“AudioCodes’ seamless interoperability with Lync made FST’s deployment easy,” commented Holger Bunkradt, Senior UC
Consultant at Glück & Kanja. “The Mediant gateways’ flexibility and scalability are very impressive and were crucial to thesuccess of the project. As a result, we can use the same platforms at all FST’s offices, helping reduce training costs andmanage spare parts more efficiently.”
