Description

Experience Level: Expert

This project involves migrating and upgrading an on-premise Cisco CUCM system to a virtualized environment in a data center. The current Cisco Unified Communications Manager platform is Version 11.5.1.12900-21 running on a Cisco Business Edition 6000 appliance with vmware Version 6.0.0 Update 3. Additional components include Cisco Unity Connection for voicemail services, an Expressway Core system at Version X8.10.2, and a Cisco Unified Border Element gateway on a Cisco 2911 device.

The successful freelancer will virtualize the Cisco infrastructure in the client's data center, upgrading CUCM to the latest supported version for their environment. This will require shifting the existing on-premise configuration to virtual machines, integrating the VMware environment, and validating all call features continue functioning as expected. Public telephony SIP connectivity must also be established through the CUBE gateway in the new infrastructure. Finally, the migrated solution should provide a robust platform for future communications updates with improved manageability in a virtual architecture. Experience architecting and implementing Cisco UC solutions in VMware is essential.
