CORETX recommended, designed and deployed Cisco Call Manager. The solution was first implemented in Liverpool, the largest of the UK sites and this was followed by a roll-out to Leeds, Belfast, Sheffield, Manchester and Glasgow, connecting all employees to a significantly updated system, rich with features and applications. Presence, hot-desking, call recording and direct dial are now helping users to work better together, across all the sites. The solution also gave Rensburg Sheppards a disaster recovery strategy for the first time. With remote servers based across multiple sites, network resilience has been greatly increased and system uptime is guaranteed, which is critical for a service-led organisation. Also, most recently, the use of advanced clustered Cisco Unified Communication Manager configuration has given Rensburg Sheppards even greater flexibility, scalability and resilience.
