1Background
NEO-ONE (www.neo-one.fr), a subsidiary of the EQUADEX Group, is an alternative
telecommunications operator in France serving small businesses and SMEs that requirea guarantee of optimized and uninterrupted service for their business.
NEO-ONE is one of the few service providers in France that can deliver a complete georedundant, cloud-based Unified Communications solution.

Challenges
NEO-ONE offers advanced business services based on IP telephony (VoIP) and SIP
trunk solutions. Integration of voice and data traffic in a single data network is a major
challenge. The aim is to eliminate the need for traditional telephony lines thereby
rationalizing costs. However, offering a reliable cloud-based unified communications
and telephony solution is a challenge that NEO-ONE confronts on a daily basis.
Many enterprises are adopting Microsoft Lync as a unified communications platform,
with the extensive advantages that Lync can offer to their organization. In order toensure full interoperability between the Microsoft Lync solution and SIP trunks,
enterprises must deploy qualified protocol conversion systems such as Enterprise
Session Border Controllers (E-SBC).
Usually, an enterprise wishing to combine Microsoft’s unified communications solution
with a VoIP infrastructure would need to invest in expensive equipment requiring costly
maintenance and support which many enterprises do not have the skills to provide inhouse. NEO-ONE therefore was looking for an economical, centralized solution thatwould combine its performance and high availability requirements in order to enable
its Lync customers to take advantage of its Lync-compatible routing and telephonyservice. The solution would need to offer full interoperability with the customers’
on-premises Lync deployments, while ensuring high levels of security, reliability andperformance.

Customers can be sure of fullcompatibility with their MicrosoftLync
unifiedcommunications
environments.

Solution
The platform selected by NEO-ONE to act as interface between its
customers’ Lync platforms and its SIP trunking solution was AudioCodes
Mediant 4000 SBC.
AudioCodes Mediant 4000 is a medium density Session Border Controller
which acts as the demarcation point between enterprise VoIP networks
and the SIP trunking service provider domain, offering protocol mediation
between the different SIP implementations. Mediant 4000 is also fully
qualified for use with Lync Server 2010 and Lync Server 2013. In NEO-ONE’scase, this means that customers can be sure of full compatibility with their
Microsoft Lync unified communications environments.
Two of Mediant 4000’s characteristics that were particularly importantconsiderations in NEO-ONE’s selection of the product were:• The capacity to convert the TCP transport protocol used in the Lync
environment to the UDP protocol used in NEO-ONE’s Business Trunkingnetwork.
• The ability to support active/passive redundancy between two
geographically distinct sites.
A major prerequisite for NEO-ONE was the high availability of this service
offering. NEO-ONE was able to achieve this by deploying two AudioCodes
E-SBCs in a redundant configuration at its datacenters in Paris and Toulouse.
The VoIP and unified communications system is connected througha special fiber-optic link, dimensioned to the service’s simultaneouscommunication needs, guaranteeing total end-to-end control of the qualityof the communication provided by NEO-ONE.
