    Multi-Vendor Agile UC - It’s a Reality and it Fuels Customer Success

    Darrel Bremer, Head of Customer Success, VOSS

    At a time when there is a lot of uncertainty in the hosted UC space due to ongoing consolidation and regular changes in strategic direction from the major UC technology vendors, service providers and large enterprises are being forced to adapt their approach to vendor commitment and service offering development.

    The last few years have seen Microsoft on a development journey from Lync to Skype for Business to MS Teams, as they search for the optimal solution that meets market demand. Cisco has also launched its share of collaboration tools, with Jabber, then Spark, and now Webex Teams. With a question mark over the strategic direction of Cisco HCS versus Broadsoft, not to mention failures such as Troppo, the messaging from vendors has been confusing at best, leaving service providers and large enterprises unclear as to what will be released next year, let alone in the next five.

    The result is that service providers and large enterprises have to question their dependence on their preferred vendors to define their UC strategy and a shift in loyalty from one or two strategic vendors to a more ‘best of breed’ approach as they recognize that they are empowered to differentiate themselves by adopting technology that suits their needs or that meets the demands of their own customers.

    From what we at VOSS see in the market today, service providers are looking at ways to abstract the business data layer, so that they can lay this data over any UC technology they feel fits their purpose. Service providers are even looking for the ability to exchange underlying UC technology 'on the fly', providing the ability to interchange from one technology to another, without the need to engage in complex cross platform migrations.

    We are also seeing a growth in demand for mixed estates (mostly driven by cost), where service providers and large enterprises want to deploy mixed estate, to provide the option of low cost basic telephony as well as high end feature rich telephony as part of a consolidated UC solution.

    VOSS-4-UC's multi-vendor support capability is perfectly positioned to help our customers achieve exactly this; they can abstract the business data layer (including sites, users, devices, lines and features) from the UC technology layer, and mix or even exchange UC technology due to drivers such as business requirements, product differentiation, or even changes in strategic direction.

    Dynamic orchestration of provisioning workflows allow our customers to seamlessly provision users across multiple UC platforms, allowing for a single view of a UC estate, irrespective of what the underlying UC technology could be. Examples of these types of deployment includes:

    • Hybrid Cisco HCS / BroadSoft architectures
    • Hybrid Cisco HCS / Webex Teams implementations
    • Hybrid HCS / low cost calling implementations
    • Hybrid MS Teams / Cisco HCS architectures

    Rich API integration capabilities also allow for the added benefit of deploying zero-touch flow-through provisioning workflows, to on-board users and all their services via platforms such as ServiceNow, onto any integrated UC technology, with the click of a button.

    In addition, the abstraction of business data and centrally captured provisioning data, all within a single provisioning platform, gives our customers the ability to perform deep analytics on provisioning trends and the usage of services, further streamlining their service offerings and operational processes.

    VOSS Unveils Microsoft Teams Direct Routing to further extend the benefits of VOSS-4-UC in Multi-Vendor Cisco and Microsoft UC

    Tim Jalland, Senior Proposition Manager, VOSS

    The Power of Choice

    Working with enterprise organisations around the globe, I’ve heard from and seen many, as an integral part of their application strategy, adopting the Microsoft Office 365 suite of productivity applications and moving to the cloud. They are also taking advantage of Microsoft Teams, included as part of the package, for their unified communication needs, particularly for knowledge workers who are regularly on the move and working with soft clients. Microsoft call this ‘Intelligent Communications’!

    But this has created a challenging question that I’m often asked, and until now has not been satisfactorily answered.

    How does this new population of users interconnect with existing systems, applications and users, often powered by Cisco solutions, so that everybody can freely communicate?

    The answer lies with the recently announced Microsoft Teams Direct Routing technology and with our recent update to VOSS-4-UC – now extended to provide a single point for managing, in a secure, coherent and consistent way a mixed Cisco / Microsoft hybrid solution.

    How Does It Work?

    Integration of Microsoft Teams clients (which are registered with the Microsoft Phone System in the cloud) is through a Microsoft Teams supported technology called Direct Routing. This connects the Microsoft Phone System into the main Cisco communication service – providing robust voice calling, superior call control and break-out access to the Public Telephone Network.

    The Direct Routing connection is carried over the Internet and is terminated in the data centre on an approved SBC, which has been formally tested and supported by Microsoft. Yesterday, we announced our first SBC partnership in this area - with AudioCodes.

    What Does This Give Me?

    Firstly – a combined Cisco / Microsoft solution supporting a wide range of end-points!

    Both types of client are supported – all Cisco end-points as well as the Microsoft Teams client – the exact profile of client and attached services being defined when a user is provisioned into the estate. Clients may be selected, freely mixed and matched dependent on the exact use or application need – be that a mobile knowledge worker, a desktop-based user, meeting, lobby or conference rooms or full video conferencing facilities. Analog devices, in particular, are supported via the Cisco solution. Should a user’s needs change – then alternative services and end-points may be selected and provisioned from VOSS-4-UC.

    Provisioning with either client is super simple through the VOSS-4-UC Quick Add Subscriber workflow (QAS) – allowing collaboration services, numbers and associated end points to be easily selected during the provisioning process.

    By also including the central PSTN break-out point into the solution, full flexibility and control is opened up for call tariffs – ensuring these can be catered to the needs of individual enterprises, call costs can be reduced, existing commercial contracts if in place with an enterprise customer can be honoured and calls between different types of client can be kept fully on-net.

    Most enterprise organisations make use of the Microsoft E3 user license (including Microsoft Exchange, the Office productivity suite and the Microsoft Teams client). The solution described here can make use of this existing user license, keeping the need to upgrade to the more expensive E5 license to a minimum.

    Deeper insight into service operations and the quality of the integrated solution, including advanced analytics that measure how the service is being consumed, and the ability to automate responses to any issues that are raised.

    Where changes to either part of the estate (Cisco or Microsoft) are made and these result in a billable change, these may be reported dynamically and automatically northbound into a suitable billing platform for timely and accurate raising of charges.

    Axians Chooses VOSS-4-UC to Manage its Cisco HCS Architecture

    Tuesday April 30, 2019 - Richardson, TX - Today, VOSS Solutions announced that Axians has followed the VOSS H.O.M.E program to transition its UC management from CUCDM to VOSS-4-UC.

    Axians, a VINCI Energies brand, offers its customers in various markets a comprehensive range of ICT solutions and services spanning business applications and data analytics, enterprise networks and digital workspaces, datacenters and cloud services, telecommunications infrastructure and cybersecurity.

    Axians became a Cisco HCS customer in 2015, providing cloud collaboration services to its network of customers. At the time of purchase, Axians’ Cisco HCS platform was managed by Cisco Unified Communications Domain Manager (CUCDM). Over the next 3 years, Axians successfully grew its HCS platform, offering UCaaS to customers across the Netherlands.

    In 2018, when Cisco announced the end of life for CUCDM, Axians took the decision to transition away from CUCDM, with the aim of addressing two critical factors:

    1. Axians wanted to reduce the level of manual administration on its Cisco HCS platform by introducing higher levels of automation
    2. Axians was keen to integrate its Cisco HCS platform into other business systems to offer a richer suite of UC services in a more seamless way

    After evaluating other products on the market, Axians chose to transition from CUCDM to VOSS-4-UC.

    To address Axians’ desire to improve the levels of automation in its HCS platform, VOSS introduced flow-through provisioning which automates the process of user provisioning by synchronizing users and their UC services with data provided by a customer LDAP server. With flow-through provisioning, VOSS can automate many of the manual MACDs that Axians had been carrying out on behalf of its customers, improving time to resolution and increasing customer satisfaction.

    As part of the automation optimization process, VOSS also introduces multiple levels of devolved administration, so that Axians can retain overall control of the platform while decentralizing various levels of administrative power down to the customer and end user level. This enables customers to have more control over their UCaaS platform and has seen an improvement in end user adoption.

    With VOSS-4-UC, Axians now has a single point of integration to interconnect its HCS platform with upstream and downstream IT systems. As a result, Axians is integrating Cisco HCS with ServiceNow, with longer term goals of integrating its contact center and Webex Teams environments as well.

    Tom Greeve, Director at Axians commented; “As a Systems Integrator, it’s our job to provide high quality and cost-effective leading edge UCaaS packages to our customers. VOSS enables Axians to provide a highly automated and flexible UC management framework that allows us to respond to our customers' requirements quickly and efficiently.”

    Stefan Peters, Director at VOSS Solutions, added; “VOSS-4-UC unlocks many new opportunities for Axians to grow its HCS platform, to integrate new systems and to adopt new technologies, and to really embrace the power of automation. We are excited to see Axians customer base grow as a result of this strong foundation that is underpinned by VOSS.”
