To design, install and maintain a single IP based unified communications infrastructure across 200 sites to support 2,500 employees. To plan and transition a migration from ISDN30 line technology to SIP-based line protocols at the Head Office site and port PSTN or ISDN2 lines at branch office sites to the centralised SIP services. To retain and upgrade the pre-existing contact centre management suite (an IPFX instance) to ensure that no downtime affects central services.


FLR Telecoms designed a central resilient

Cisco Unified Call Manager solution with the IPFX overlay product supported by Cisco CUBE technology for SIP connectivity. The migration project was implemented over four months commencing at the core and then transitioning each office on a fixed plan.

New Cisco data switching technology was installed at the core and at each branch office, which is supported and maintained by FLR Telecoms and connected to the existing MPLS network.


A state of the art IP based unified telecommunication estate offering reduced operating costs through centralised SIP based line services. Improved availability through a much-reduced line plant implementation across the Spicerhaart estate.
