    An Insight into VOSS Phone Server - Launched this Week

    Tim Jalland, Senior Proposition Manager, VOSS

    The last four months have seen unprecedented levels of uncertainty and change in the economic environment. Organizations have had to reconfigure and work from home. Telephony and UC solutions are at the heart of this, but how to continue in this environment with some level of BAU, improvement work, migration activities and running existing services whilst not introducing undue risk or cost?

    At VOSS we have been regularly asked about tools, services and ideas we can provide to assist with this process. One of the outcomes is the newly announced VOSS Phone Server, which can be used alongside Cisco HCS, Cisco CUCM/Enterprise, Avaya Aura, or Microsoft Teams – in either on-premise, managed service, or cloud delivered solutions.

    VOSS Phone Server offers complementary phone registration and telephony capabilities, offloads the main telephony solution (including licenses), and provides a level of agility to the overall solution. It is designed for:

    • Extending the lifetime of existing devices that may become unsupported as the main telephony platform is upgraded to the latest manufacturer software – perhaps to take advantage of a new capability or to mitigate a security concern.
    • Assisting with a planned migration to a new telephony solution. Existing devices can be transferred to the new solution and connected to it via the Phone Server. The existing phones, with numbers, can continue to be used during the migration process with a minimum amount of disruption.
    • Taking advantage of the wide range of new multi-vendor phones, devices and soft clients that have become available – at lower acquisition and license costs, and with new feature options (such as ‘green’ standby options) - to provide scalable, standard telephony at places such as lobbies, reception areas, meeting rooms, branch offices and even home working locations.

    VOSS Phone Server can be fully administered from VOSS-4-UC, and easy to use workflow wizards are provided to make the moving of phones between the main telephony solution and the phone server quick and error free. Phones can be moved either way!

    Here is a high-level diagram here to show you how this all fits together – contact VOSS for more detail or download the full solution brief.



    ✓ Extends life of existing devices (out of support phones)
    ✓ Reduces on-going Cisco/Avaya license costs
    ✓ Extends choice for new device purchases
    ✓ Provides access to full enterprise call control

    VOSS Solutions Announces VOSS Phone Server to Extend Lifetime and Maximize Investment of Telephony Assets

    Richardson, TX - Monday June 29, 2020 - Today, VOSS Solutions unveiled the latest edition to its product portfolio, VOSS Phone Server, designed to extend the lifetime and maximize the investment from existing assets, whilst reducing operating costs in large scale distributed telephony networks.

    VOSS Phone Server operates as a registration and telephony server, connecting phones and other devices into existing telephony estates. In doing so, it provides a simple and straightforward mechanism to bring a wide choice of multi-vendor devices into systems such as Cisco HCS and Cisco CUCM, Avaya Aura, and Microsoft Teams.

    Its principal applications are to:

    • Extend the lifetime of existing devices that become unsupported as the main telephony platform is upgraded to the latest software
    • Provide scalable, standard telephony at lower purchase and ongoing license costs at places such as lobbies, reception areas, meeting rooms and branch offices
    • Assist the migration to new telephony solutions, allowing existing devices to connect quickly and simply into the new estate with minimum disruption
    • Offer the option of connecting more traditional third party (SIP) phones and analog devices (ATA adapter) into solutions such as Microsoft Teams (which are designed to primarily cater for mobile and PC soft clients)
    • Concentrate dispersed devices – home workers with remote devices – simply and cost-effectively back into the main Cisco or Avaya solution

    VOSS created Phone Server in response to the challenge of connecting a wide range of existing, new and multi-vendor telephony devices into solutions such as Cisco, Avaya and Microsoft. With VOSS Phone Server, organizations can simply and cost-effectively integrate these devices, extending the lifetime of existing assets and opening up options to take advantage of the wide range of third party devices available, without being tied in to a single vendor; reducing ongoing operating and license costs. This means that organizations can seamlessly connect traditional devices, phones and analog points into new UC platforms.

    Administration of the VOSS Phone Server is from VOSS-4-UC, which offers an intuitive web portal to install and operate the new technology. Existing devices may be quickly and easily migrated to the Phone Server using the provided workflow wizards.

    Bill Dellara, VP Product at VOSS Solutions commented; “VOSS Phone Server extends the wealth of benefits found in VOSS-4-UC, empowering organizations to manage and control their entire telephony estate from a single intuitive web portal. This new functionality will enable our customers to access impressive operational savings, as well as the good business practice of getting the most out of existing investments.”

    VOSS for Retail - A UC Transformation Story

    Derek Lipscombe, Sales Director, VOSS Solutions

    It is widely recognized that the worldwide work-from-home trend has dramatically accelerated both the adoption and penetration of collaboration tools, as organizations across all industries respond to supporting remote workers with video and other online team collaboration tools.

    A broad range of advanced collaboration tools are being adopted, sometimes too quickly, in that the deployments are tactical, largely unmanaged, and almost always not well integrated with the existing business communications platforms. As a consequence, VOSS has experienced a significant spike in interest from enterprise organizations who approach us with the goal of applying our UC management automation technology to help manage, integrate and simplify the administration of their evolving and complex communications platforms.

    Another unexpected implication of the stay-at-home regulations has been the incredible pressure the retail industry has faced, grappling with the unprecedented levels of online orders pouring in from consumers “shopping from home”.

    This has resulted in increased demand for VOSS UC management from the retail sector. And it’s clear that our solution is already bringing a wealth of benefits to retail customers across the world. We recently published a collection of use cases from the retail industry to highlight some of the many ways that they are deploying VOSS-4-UC and VOSS Assurance, to underpin their communications platform and to support their UC transformation journey.

    So, what can VOSS’ UC management and automation tools really do for the retail industry? And, how can VOSS help retailers with their digital transformation?

    In this collection of case studies, we look at the pressure that retailers are under to perform in a highly competitive, high volume, low margin business.The need to be nimble and to respond to change fast becomes the secret to a retailer’s success. And, digitization and ever-increasing levels of integrated automation change the game.

    The Covid-19 pandemic has exacerbated this pressure. Every retailer has had to rethink their business model, to support radical changes to customer buying habits and to the employee workplace, and then implement changes to their UC infrastructure quickly and efficiently. Deploying these changes in such challenging time constraints would be impossible without automation.

    Automation is the key.

    In fact, if you read our use cases, a desire to harness VOSS automation to introduce flexibility is at the heart of every customer story.

    Here are just some of the challenges we hear:

    • The need to be able to migrate to more modern technologies, such as video and team collaboration tools
    • The need to integrate new UC capabilities with existing technologies to sweat those assets where appropriate
    • The need to centralize and rationalize UC platforms and deliver a consistent and reliable solution to the evolving store locations and needs - having a centralized platform where the UC capabilities are centrally deployed and then devolving the required services to the distributed stores and depots massively increases productivity
    • The need to be able to deploy the new capabilities, such as store management tools, quickly and efficiently
    • The need to quickly and seamlessly integrate new UC solutions with existing business processes to ensure the greatest business benefit from the automation
    • As the dependency on UC increases, this creates the need to step up the level of monitoring, management and analytical reporting of the UC platforms

    The fact that VOSS addresses all of these challenges - and so many more - is driving our growth in the retail space.

    Read more about how we support the retail industry, and how we can help you on your UC transformation journey, here. Or, for more information, please contact us.

    Moving from Avaya to a New UC Platform? Think VOSS & M2UC

    Tom Turrington, Migration Team Lead, VOSS

    One of our current migration projects involves a migration of ~30,000 users from Avaya to Cisco UCM for a large international insurer with offices and call centres in many sites across approximately 15 countries.

    As with any migration, once the design of the new system is complete, a robust process and a suite of tools is required to ensure that every batch of the migration can be converted to the new design in a consistent, repeatable manner, with minimal errors.

    Whilst there are a core set of concepts, features and settings that exist in both UC platforms - such as devices, call pickup groups and hunt groups - there are various features that work differently or simply do not exist in the othaer system (coverage paths for example).

    This is where VOSS’ tried-and-tested migration methodology and flexible tooling (M2UC) come into their own.

    M2UC provides the ability to import data from the source platform, map each individual feature and data item between the systems where necessary and manipulate it with a set of rules that ensure the data is transformed exactly as required. Different batch sizes can be handled with ease (in this case one batch per country) whilst processing and provisioning each batch takes just a matter of minutes, tying up human resources for as short a time as possible.

    Additionally, there is the capability to augment the data and apply templates (for example to convert one phone type into another). Optionally, the data can be exported, checked by the end customer and if required, updated - all prior to provisioning (as was the case with this migration).

    These features, amongst others, mean that M2UC has met every requirement from both the service provider and the end customer. The flexible design and extendability of M2UC has also meant that extra features can be added with short turnaround times. An example of this is the customer’s desire to set random passwords which they generated, sent to the migration team, and were merged into the data.

    In order to streamline the workflow further, reduce customer effort, and speed up the migration, VOSS created the ability to generate random passwords of user-definable length within the rules, tested the new functionality and added it to M2UC - all within a matter of days.

    In addition to its flexibility and extensibility, M2UC has been designed with a robust user-friendly interface. Whilst here at VOSS we are more than happy to conduct the entire migration, our end user portal enabled the handing over of the running of this migration to a small team within the service provider, who are successfully processing and provisioning further batches. The team is currently running several weeks ahead of the migration dates - with minimal input from VOSS (simply providing a support role), minimising costs whilst ensuring maximum accuracy.

    For more information about M2UC, or to discuss your UC migration project - whether involving Avaya or another UC platform, please contact us.
