Examples of a Cisco Call Solution

Business Edition 6000 - Insurance

An mid-sized insurance firm with 600 employees needs a new phone system. They were using an outdated PBX box (Phone Branch Exchange) until now and they realised they were long overdue to upgrade to VoIP because of the potential cost savings, reliability and security.


The IT staff were surprised at the ease and speed of the installation and how intuitive it was to manage. It was perfect for their new hybrid cloud network.


After its implementation, the benefits of the solution were clear, call times were better and customer feedback had improved. Due to the single number reach feature of the new phone system, staff that were frequently out of the office were able to receive their office phone calls to their mobile device.

Business Edition 7000 - Pharmaceutical

A large pharmaceutical company had just taken over another business, doubling their employee count to 4000 employees. The IT director concluded that they needed a new phone system which could be easily managed and was flexible so that any further expansions of the business could be handled without issue.


After looking at a number of solutions, they decided that Cisco’s Business Edition 7000 was the best option for their environment. It’s centralised management suited them well as their employees were spread in many different locations across the world and yet with the use of Cisco’s platform, all of their users could still be managed from one location. The pharmaceutical company had a Cisco call centre already which was seamlessly integrated with their new system.

How we can help you

Working with us

The rate of change in the modern technology landscape is greater now than it has been for the last 20+ years. This makes it critical for companies who want to remain competitive to remain flexible in their ability to consume new technologies. The further a company falls behind, the greater the effort required to catch-up to the current benchmark.


We work closely with companies to build platforms and roadmaps. Our solutions maintain a good balance between remaining flexible enough to incorporate new technologies that can advance the business, whilst ensuring that a core focus remains on delivering tangible outcomes.


Throughout the engagement process, we will provide ongoing consultation and feedback that helps determine which technologies to look out for, where they can be a good fit and how they can be incorporated into the environment in question.
