    UC Migrations: Save Time and Reduce Capacity for Errors with Automation Workflows

    Tom Turrington, Migration Team Lead, VOSS

    Anyone that has been involved in UC migrations knows that it is naturally complex - from discovery to provisioning. Here at VOSS we have, over the years, built our migration toolset (M2UC) and developed a robust strategy to deal with every migration. Based on the data warehouse concept of ETL (Extract, Transform & Load) we have extended the UC migration process to become DETVL (Discover Extract, Transform, Validate & Load).

    However, whilst we can normalise a migration, the complexities inherent in each stage remain. M2UC brings massive amounts of power and capabilities to migrations and we are always looking at ways to streamline the process. This is a difficult balance between not limiting the available operations while reducing the number of actions required and automating tasks as much as possible.

    To this end, we have developed the concept of Workflows.

    Workflows neither remove nor limit any of the power of M2UC but allow the automation of tasks. Operations can be chained together to create powerful sequences of events and actions can even be set to run in parallel.

    In addition to the ability to run all major operations via the Workflow GUI, at any time it is possible to do a “deeper dive” into the data, adjusting Rules and information as required. As soon as new Sources/Targets/Data-sets/Batches/Rules are developed they become available for use in the Workflows.

    All of this is achieved through an intuitive GUI, with the ability to drag and drop actions into placeholders. Workflows can be named, saved and re-run as often as required and can consist of a few operations (eg provisioning users, phones and lines and associating them together in a set order) to completing an entire migration.

    All actions undertaken via Workflows are logged in the usual way, with the initiating operator and the result of each action recorded. Workflows are linked to Projects and are backed up as part of the Project backup functionality.

    Look out for a video demonstrating this new functionality shortly - an entire migration from one click! For further information please contact us

    Thanks for a great ENGAGE, Avaya!

    Adam Furman, Presales Engineer, VOSS Solutions

    After signing up as a partner with the International Avaya User Group towards the back end of last year, we were excited about the prospect of exhibiting at our first Avaya ENGAGE in 2020.

    In case you missed it, the event took place February 2 - 5, in Phoenix Arizona.

    The theme of the show? ALL IN. The organizers were encouraging us to make new connections; network with peers from across the globe; spark ideas; get involved; go ALL IN… And we certainly did.

    This was an action-packed few days of networking. It was a pleasure to catch up with some of our existing customers and share our latest developments for Avaya UC management. We also had some dynamic conversations with prospective customers, who were at the show to learn more about tools such as VOSS-4-UC, and our ability to make the management of Avaya-only - and multi-vendor UC - environments easier. The opportunity to meet with so many Avaya folks was also much appreciated, as we found many new opportunities to work together in 2020.

    Our booth was busy with people looking to solve UC-related business problems, and we were able to show how VOSS can introduce advanced levels of automation and workflows to improve business processes, which in turn offer a better service to end users (either employees or customers).

    We look forward to participating in next year’s event. In the meantime, to learn more about VOSS for Avaya, please get in touch, or have a look at the following links:

    VOSS for Avaya - Achieving True Multi-Vendor UC

    Dan Payne, CTO, VOSS Solutions

    Wednesday February 5, 2020

    I’m writing this post from Phoenix, at my first Avaya ENGAGE conference. It’s been an extremely busy week, with many breakout sessions, keynotes and of course exhibiting our exciting new solution on the show floor

    We formally launched our latest VOSS for Avaya solution this week, on the opening day of the show. It’s very straightforward: We are now offering simple and efficient management and assurance of integrated Avaya and Microsoft collaboration solutions. But let me not cover old ground, you can find out more, here:

    What I will say is that I’m excited about the VOSS for Avaya solution, as there is clearly a huge appetite for managing Avaya UC environments. Talking with the visitors at our booth, it’s clear that everyone is looking for a way to simplify their operations. Some of the key problems folks are dealing with are:

    • Keeping up to date with the latest Avaya innovations and features
    • Centralizing management (bringing consistency) of the ever-growing and changing platforms
    • Keeping up with day to day requests for user MACDs.

    Whether your organization operates an Avaya-only solution, or whether you are creating a best-of-breed solution that includes Avaya plus other vendors such as Microsoft Teams, I am confident that VOSS will manage your UC platform far more effectively than you do now.

    VOSS-4-UC provides a coherent single-pane view of all UC applications, services, endpoints, and most importantly, the users. It provides administrators and end-users alike, with an intuitive interface to get the jobs done that are most important to them, cutting out the noise and complexity that comes with UC management. The UC complexity is dealt with in the background by a combination of flexible workflows and templates to push configuration according to your specific best practices and conventions.

    In addition to the single-pane user and service management, our integrated Avaya and Microsoft solution takes advantage of Microsoft’s Direct Routing technology to connect the two. This combines the excellent collaboration capabilities of Microsoft Teams with the mature and feature-rich Avaya UC and CC solutions, allowing customers to enjoy the best experience possible

    Although we only officially launched this week, we have been working hard over the last couple of months, to bring this solution into reality for one of our North American partners. They are officially in production with some pilot customers and are planning to onboard many more over the next couple of months!

    So, if you’re at Avaya ENGAGE, stop by at booth 742 to find out more. You may also be interested in taking advantage of a special exploratory workshop that we are offering to show visitors.

    If you aren’t at the event but are keen to learn more, please don’t hesitate to get in touch.

    VOSS Extends Management of Avaya Aura UC and CC Enterprise Systems to Microsoft Teams Allowing Full Co-Existence, Choice of Clients, and Migration Opportunities

    Monday February 3, 2020 - Avaya Engage, Phoenix Arizona - TODAY at Avaya Engage, VOSS Solutions revealed that the company has extended its efficient management of Avaya systems to add integrated management of Microsoft Teams, from a single point of control. The solution addresses the growing requirement from enterprise organizations to take advantage of the market leading capabilities of Microsoft Teams, while continuing to benefit from their investment in existing Avaya systems. 

    With VOSS-4-UC, organizations can now manage these combined environments efficiently and seamlessly, so that users across both systems can communicate freely, whatever their choice of client. VOSS-4-UC provides a coherent single pane view of all UC applications, services, end points, and network infrastructure. It offers feature parity and management with the latest UC applications (single stack: Microsoft and Avaya) and user on-boarding through intuitive workflows (Quick Add Subscriber) or bulk loaders (customer provisioning). VOSS-4-UC on Avaya systems gives a comprehensive range of controls to manage users, their associated services, devices and numbers. In turn, it uses Microsoft’s Direct Routing technology to connect the two platforms.

    VOSS-4-UC already provides management for existing Avaya UC solutions through an intuitive web portal, with access being controlled through comprehensive role and access profiles. All changes are managed and recorded into the VOSS-4-UC transaction log and this may be exported for further offline analysis and audit purposes. The management may be extended out to manage a Microsoft Teams solution through the same web portal, providing a single view across the combined UC solution of all users, numbers, devices and associated services.

    Bill Dellara, VP Product at VOSS, commented; "This is a very exciting proposition for Avaya users who have previously resisted installing a UC management layer, but who wish to take advantage of new collaboration technologies such as Microsoft Teams. The deployment of VOSS-4-UC on existing Avaya installations is quick and easy, using a process known as Sync and Overbuild, which provides a fast start for customers with existing installations that need improved and multi-vendor management. We encourage organizations to visit us at booth 742 at Avaya Engage to find out more."

    There are many benefits for organizations who wish to take advantage VOSS-4-UC management for Avaya and Microsoft Teams, for example:

    • Provides comprehensive control and management of Avaya enterprise voice applications for UC and CC
    • Extends the benefits of VOSS-4-UC to users with Microsoft Teams – providing a single point of control for all numbers, users, their services and their end-points
    • Offers operational controls, audit and access profiles to manage changes across the combined estate of users and devices
    • Allows both Avaya and Microsoft clients to be deployed and freely communicate, including on-net calling between client types
    • Uses Microsoft Direct Routing technology to extend mature call control and robustness of Avaya Enterprise Voice – including central PSTN breakout services
    • Builds on existing Microsoft E3 licenses – keeping license costs to a minimum
    • Enables full flexibility, control and choice of tariff plans – reducing call costs
    • Provides a single and consistent integration point into high layer billing and reporting systems

    To find out more about VOSS Solutions and VOSS-4-UC, please email info@voss-solutions.com, or visit us at Avaya Engage, booth #742, February 3-5, 2020.

    VOSS will be running an exclusive offer to Avaya ENGAGE visitors. Find out more, here.
