Company Profile

A global biopharma company with operations in about 40 countries. This was a truly global Microsoft Lync deployment of approximately 13,000 users in various locations.

Business Need

As an early adopter of Microsoft Lync 2010, this global enterprise was already taking advantage of Lync’s wide-ranging functionality such as instant messaging and presence, conferencing and peer-to-peer voice calling.

Early in 2013, they took the decision to undertake a company-wide upgrade to Lync 2013. With Lync having become a core solution for the company, 1Plex were brought in to take responsibility for designing the Lync 2013 infrastructure as well as delivering the implementation.

They needed to deploy a fully-certified voice connectivity solution for Lync 2013 to ensure seamless interoperability and high reliability. The solution needed to be able to connect all the existing voice solutions already in use at various locations including Siemens HiPath 4000 PBXs and Openscape, Cisco Call Manager, as well as the existing Lync 2010 installation. In addition, they required scalable interconnectivity with a variety of PSTN provider networks in a number of different countries.

Most importantly, the voice connectivity solution needed to be flexible enough to enable the aforementioned interconnectivity in a seamless manner which would not impact on existing functionality. The migration of users would have to be as smooth as possible in order to gain their confidence and ensure the success of the project as a whole.


As well as a global deployment of Lync 2013 and Lync Server 2013, the company deployed Unified Messaging in Microsoft Exchange Server 2013 in order to add voice mail to Lync enterprise voice.

To achieve this 1plex installed the AudioCodes Mediant 1000, a fully Lync 2013 certified hybrid session border controller and media gateway platform. The Mediant 1000 supports up to 192 concurrent voice sessions and 6 E1 interfaces per device. With AudioCodes’ advanced underlying voice processing technology, the Mediant 1000 offers wide-ranging SIP protocol interoperability with virtually any IP-PBX and is homologated with TDM service provider networks worldwide. 1plex worked closely with Audiocodes and Workstream People to ensure a successful and rapid implementation.

By the end of 2013, all 13,000 employees were provided with instant messaging, voice mail, presence and conferencing capabilities, and Microsoft Lync Mobile had rolled out to more than 3,000 employees. Lync replaced the old legacy phone systems and the vast majority of enterprise voice users work from headsets, with only a limited number of handsets being deployed.

To extend the Lync experience to meeting rooms, 1plex also installed a number of Crestron Lync Room Systems to further enhance their Lync experience.


By upgrading to the latest release of Microsoft Lync and establishing universal communications throughout the company, the company can better support its workforce, reduce costs and enable flexible, effective collaboration. Since replacing its legacy conferencing services with Lync 2013, Lync Server 2013, and Lync Mobile, they have reduced web-conferencing costs by more than US$1.4 million a year. It is also believed that Lync will help enhance employee productivity and indirectly contribute to increased revenue. Employees use Lync enterprise voice, messaging, conferencing, and other functionalities to collaborate more easily and effectively with their colleagues inside and outside the organization.

“Lync has definitely changed communication and the shared culture. It has helped them become a more effective organization.”
