    A Great Example of a VOSS Customer's Five-Day Workshop to Kick-Off their Transition from CUCDMv8 to VOSS-4-UC

    Henry Barton, VP Operations Strategy, VOSS Solutions

    Increasing numbers of Service Providers are commencing Overbuild transitions from the HCS CUCDMv8x Domain Manager to VOSS-4-UC. With Cisco recently issuing an End-Of-Sale notice for CUCDMv8x, planning for transition to VOSS Solution's next generation VOSS-4-UC domain manager become that much more important, if Service Providers have not already started.

    In this post, I'll share a recent example of a service provider embarking on a 5-day workshop to kick-off their transition program. But first, some background.

    The transition path to VOSS-4-UC is well-proven, and increasingly well-trodden as more and more HCS partners choose VOSS-4-UC over competing UC management tools. Currently, VOSS is working on fifteen active HCS transitions, with many more in the planning phase. These HCS Service Providers, based in EMEA, the Americas and APAC, are using the VOSS MiGR8-2-UC toolset to accelerate the process (option 1 in the below diagram). Altogether, we estimate that these Service Providers have a pipeline of c.2500 Customers and 12,000 Sites in transition, ranging from 120,000-User Customers down to 20-User Customers; a serious undertaking. Typically, the larger Service Providers have between 50 and 200 large/medium-size Customers to transition and this is a significant task. This will consume a large amount of resources and time, if performed manually (option 2 in the below diagram).

    Considering the HCS Dial Plan

    Experience shows us that a critical issue to consider is the HCS dial plan that you wish to utilize for the future HCS platform under the OPA model. Cisco and VOSS have invested an enormous amount of time to perfect the HCS "Evolution" (or looping) dial plan; including testing. This is an development of the "Classic" HCS dial plan, and provides a significant improvement in terms of resource utilization and flexibility, whilst still supporting the wide range of features and territories/countries that HCS Providers cover. Even with Cisco pulling back from dial plan certification under the OPA model, VOSS is able to support Providers with the Evolution HCS dial plan and it is strongly recommended that HCS Providers switch to the latest dial plan during the transition from CUCDM-8x to VOSS-4-UC.

    So far, all the Service Providers we are talking to are electing to move from the Cisco HCS "Classic" dial plan loaded by CUCDMv 8x to the new Cisco HCS "Evolution" dial plan under VOSS-4-UX. As Cisco moves to its Open Architecture approach to HCS, the Evolution dial plan is where all the 'know-how' now resides. Plus, VOSS-4-UC also supports inclusion of custom dial plan schemas, through a set of adaptations.

    Getting Started

    The process of starting an Overbuild Transition programme may seem challenging to Service Providers and the tempation can be to get tied up with time-consuming rounds of testing on reference platforms. In practice, the transition process has been carried out successfully by multiple customer types around the world. Hence, VOSS believes that a Service Provider's goal should now be to seek the fastest way of switching platforms safely and efficiently, to minimize costs. Plus, they should seek to maximise the benefits when moving to VOSS-4-UC, which includes fully exploiting the latest capabilities of the Cisco HCS architecture and the VOSS-4-UC agile framework.

    This is where the VOSS Global Services team can help. With experience that we have built up over the last two years, we have deep field knowledge of the transition process and have heavily invested in enhancing VOSS-4-UC and our MiGR8-2-UC transition tools to accelerate switch-over. No other vendor has anywhere near the years of experience that VOSS holds, nor the advanced toolset to both minimize risk/time and maximize the benefits.

    We believe the best way of kicking off an Overbuild programme is to plan a face-to-face launch workshop. Without doubt, the hardest step is to migrate the first three or four customers. Getting the real-time experience with the first customers will then make planning for the rest of the customer base much easier.

    How to Transition to VOSS-4-UC in Five Days

    As a very recent case example, VOSS has just completed a 5-day kick off workshop with a major North American HCS Service Provider. We think this offers a valuable blueprint that we recommend to other Service Providers to help 'fast-track' their Transition Programme.

    Here was the workshop format:

    • Pre-workshop preparations:
      • VOSS Global Services remote support with upgrade of the CUCDMv11.5.1 production cluster to the latest VOSS-4-UC v18.1 version, plus installation of a MiGR8-2-UC-for-Overbuild server.
      • VOSS Global Services audit of the VOSS-4-UC platform and installation of our latest best-practice configuration settings for Overbuild operations.
      • A high-speed test-run,with the transitioning of a reference customer from the production CUCDMv8x to the production VOSS-4-UCv18.1 platform.
    • 5-Day workshop:
      • Team of 10 from the Service Provider, comprising: Project Management, Solution Architects, HCS Platform Management, Operations Implementation, Billing Integration and Training. Team of 4 from VOSS Global Services.
      • Review of the VOSS-4-UCv18.1 platform set-up and VOSS Global Service's latest recommended configuration settings.
      • Detailed review of the Overbuild Transition process, including the results of the reference customer testing.
      • Parallel processing of three customers: Extraction of data from CUCDMv8x:
      • Re-loading into VOSS-4-UC using MiGR8-2-UC; Sync and Move tasks; Dial plan switching processing; and Entitlement calculation.
      • Focus on hot topics, including: Enhanced Provider menu design for Overbuild; Cluster Syncing best-practice; AD integration; Dial plan Schema enhancements; Site Default settings; Number Inventory management; CUCDMv8x to VOSS-4-UC cutover principles

    During the 5-day workshop, we demonstrated the rapid handling of multiple customers with several thousand users and phones at over 60 sites, including switch from HCS-G1 Linked Sites to HCS-Evolution-Type4 support. In parallel, this was a very efficient way of discussing VOSS-4-UC 'best-practice' operations.

    The next step for this Service Provider is to plan for the transition of several hundred customers in batches of up to 20 customers at a time.

    The Time is Now

    Our perspective at VOSS is that this is a good time for Service Providers to move rapidly across the transition 'bridge' from the original CUCDMv8x platform that VOSS OEM'd through Cisco, to the latest VOSS-4-UC platform.

    CUCDMv8x supported the original HUCS and HCS architectures, but technologies have now moved on. The all-new VOSS-4-UC architecture is designed to help Service Providers support the latest generation of UC platforms with much deeper levels of integration and much greater flexibility; all within the highly standardized VOSS framework. Let us help you get there fast!

    VOSS Shares Plans for Cisco HCS Partners as Cisco Announces End of Life for CUCDM

    VOSS-4-UC Unlocks Potential for HCS Partners to Compete Effectively for Growing UCaaS Market

    Tuesday August 14, 2018 - Richardson, TX - Today, VOSS Solutions issued guidance to Cisco HCS partners following Cisco’s announcement that Cisco UCDM (Unified Communications Domain Manager) will reach end of sale in February 2019.

    In Cisco’s announcement dated August 14 2018, the CUCDM product lifecycle will end in February 2019. CUCDM has already been removed from all Cisco HCS perpetual bundles, but is still available as an independent SKU. However, the list price for the independent CUCDM SKU is now approximately four times the price of the previous HCS bundle.

    Mike Frayne, CEO at VOSS Solutions, commented; "Our message to CUCDM users is to not panic. The end of life of CUCDM does not mean that HCS partners have to follow an immediate rip-and-replace 'revolution' of their UC management component. VOSS empowers HCS partners to take control; to choose the best transition path for their business and to dictate their own transition timeframe".

    A key factor of the VOSS transition offering is that, with the wealth of experience that VOSS has gathered over 12 years of providing the CUCDM technology to Cisco and working with the HCS partner community, VOSS is able to take over the support of CUCDM licenses immediately, to provide a continued service to HCS partners while they decide on the future of their UC management component. Importantly, VOSS is the only provisioning partner in the Cisco ecosystem that is offering unconditional free trade-in for all existing CUCDM licenses. Furthermore, VOSS is the only vendor that will allow HCS partners to immediately acquire VOSS-4-UC licenses that deliver the same functionality that CUCDM provides, to help HCS partners avoid absorbing the significant price increase associated with CUCDM.

    One concern for Cisco HCS partners will be the risk involved in transitioning their HCS platform to a new UC management tool, and the migration of their customers from one platform to another. With so many users, devices and services to consider, and with so much data in the live environment, this will be no mean feat.

    VOSS has been operating a H.O.M.E program for the last 18 months, carefully guiding major HCS partners away from CUCDM and onto the VOSS-4-UC management platform. When HCS partners take the decision to move to VOSS-4-UC, they will receive all the existing functionality that is currently in CUCDM plus so much more, while minimizing the impact on service continuity. VOSS-4-UC includes many additional features, such as coordinated management for Webex Teams Hybrid, customized UC management to better align with operational processes and integrate with back office systems, and also UC management of both Cisco, Broadsoft, and Microsoft UC. With VOSS, HCS partners will benefit from new modules, such as VOSS Assurance & Analytics for monitoring, troubleshooting, data mining, and access to contextual insight and improved reporting.

    Henry Barton, VP Operations Strategy at VOSS, added; "After purchasing licenses from VOSS, HCS partners follow a structured and highly automated transition program; migrating phones, devices and users over to the new UC management platform seamlessly and with minimum impact to end customers. We have done this many times already, so HCS partners can expect a a robust and proven process that delivers the value of the of the new platform while minimizing the impact on the partner and their customers".

    A key driver for HCS partners to choose VOSS-4-UC is their growing interest in differentiating their offering to the UCaaS market. All end customers that choose to consume their UC as a service expect the cost and time-saving benefits of a standard cloud-based solution, but also require a certain level of customization to suit their business processes and workflows.

    With more than 100 adaptations delivered to HCS partners to date, VOSS enables an organization to tailor the sophisticated VOSS-4-UC operations management platform to suit the specific needs of the business, without complex, labor-intensive coding or the associated time and budget implications. These adaptations mean that Cisco HCS partners can easily differentiate their UCaaS offering, to create custom UC environments that suit particular business cases, depending on their customers' size, industry, and geography.

    To date, 33% of the organizations that have production HCS platforms have made the decision to transition from CUCDM to VOSS-4-UC. As a result, more than 1.2 million production end user devices (EUDs) have already moved from CUCDM to be managed in production by VOSS-4-UC. In total, there are active transition plans to move 50% of all the production HCS EUDs to a VOSS-4-UC managed platform.

    Mike Frayne concluded; "HCS partners have existing customers on their platforms and they need to provide them with continuity under the contracts they have in place with these customers. As a result, HCS partners need a strategy to deal with CUCDM no longer being available over time, and a transition plan that not only mitigates the risks and minimizes the impact on their customers and operational capabilities, but also maintains their margins by avoiding having to buy new licenses to replace CUCDM or pay more for CUCDM functionality. VOSS is uniquely positioned to help manage this business continuity and at the same time provide enhanced capabilities to both improve but simultaneously maintain their end customers’ experience. VOSS-4-UC is the leading UC management vendor and is able to deliver the additional features and capabilities the market needs, while managing the transitional risks so that HCS partners can evolve to the new HCS reference architecture in a controlled, seamless manner."
