Planning service
How the planning service works
With over 20 years experience in design and delivery of traditional and unified communication systems, Visionist will provide you with a rapid assessment of your current telephony service, whether a legacy or an existing VoIP/IPT service.

We identify rapidly deployable service improvement opportunities and engage with senior stakeholders to understand your IT strategy. We will provide you with a high level requirements specification for a Voice over IP (VOIP) service and an appropriate migration strategy and high level plan.

With our proven successful delivery of similarly sized projects of similar complexities within government, we provide you with a short list of potential suppliers to evaluate. Visionist can manage the evaluation process, making recommendation for a preferred technology and procurement route. We are able to assist with supplier and product evaluation, or to run the entire process for you.

As we are truly independent with no specific ties to any vendors, we are able to identify and plan the service which is a best fit for your requirements.

Once a supplier and appropriate technology are identified, we can to provide a full project planning lifecycle, from early engagement to supplier management and ultimately provide live operational support of the services.

Setup and migration

Setup or migration service available
How the setup or migration service works
Visionist have delivered many integrated and unified communications transition services to central government clients (20,000+ users). We have also delivered similarly sized desktop and infrastructure transition and transformation programmes.

Visionist have a first rate understanding of the various technologies, suppliers, procurement routes and most importantly, challenges and lessons learned, which we will ensure are identified as part of our migration strategy.

By providing our migration services, we will track risks, issues and dependencies and manage the various suppliers through the migration process, from number porting to platform setup, configuration and operational readiness review.

User Communication is an important aspect of the success of any telephony transition service and we will ensure that you have a clear communications strategy and sample templates to use during migration.

We will engage with the business to understand any nuances in their ways of working (such as the Private Office) to fully appreciate HOW they need to work, thus ensuring minimal impact to their ways of working during migration.

Quality assurance and performance testing

Quality assurance and performance testing service
How the quality assurance and performance testing works
Visionist continually monitor the quality of our services we provide to you and that of the telephony and infrastructure service provider.

We will measure our services against an agreed set of deliverables, which we will report and agree with you at regular service management meetings, to suit your requirements.

We measure the quality of the end service provider through our extensive experience of the various technologies, best practices and baseline measurements from other services which we have delivered.

We are able to provide performance monitoring of a telephony service using synthetic transactions generated by a performance monitoring device. The devices will provide a MOSFET score which provides an indication of network readiness and capability, along with an anticipated call quality baseline.
